Why on a 2006 cobalt do I not have power to the obd2 plug and the gas gauge not registering as well as the odometer just has a blank screen


Did you check the fuse that supply's battery voltage to pin # 16 at the DLC - diagnostic link connector ? That's where you plug your code reader in . The lighter fuse - 15 amp located in the under hood fuse box supply's battery voltage to pin #16 . The fuel gauge not working could be any one of a number of thing's , without testing an checking for DTC'S - diagnostic trouble code's I would only be guessing . Checking code's in the instrument cluster an PCM should be done by a qualified repair shop. The fuel level sending unit in the fuel tank is a direct input to the PCM/ECM - engine computer , the PCM / ECM sends this info too

The instrument panel cluster (IPC) displays the fuel level as determined by the powertrain control module (PCM)/engine control module (ECM). The IPC receives a GMLAN message from the body control module (BCM) indicating the fuel level volume. The fuel gage defaults to empty (E) if:
• The PCM/ECM detects a malfunction in the fuel level sensor circuit.
• The IPC detects a loss of GMLAN communications with the BCM.
When the fuel level is less than a certain low percentage, LOW FUEL message displays in the driver information center (DIC).

Odometer
The vehicle odometer is calculated and stored electronically in the body control module (BCM) and is sent via GMLAN to the instrument panel cluster (IPC) for display. The BCM calculates and stores the mileage based on the vehicle speed GMLAN message from the powertrain control module (PCM)/engine control module (ECM). The IPC displays the season odometer information from the BCM in the driver information center (DIC). The odometer will display error if the IPC detects an invalid odometer data from the BCM. After an invalid odometer data is received from the BCM, the IPC will display the last known odometer reading for 1.5 seconds before error is displayed in the DIC.

These can set a few different DTC'S

DTC B0158
DTC B2961
DTC P0461 (2.0L and 2.2L)
DTC P0461 (2.4L)
DTC P0462 (2.0L and 2.2L)
DTC P0462 (2.4L)
DTC P0463 (2.0L and 2.2L)
DTC P0463 (2.4L)
DTC P0464
DTC P0520


So , i suggest you take your vehicle to a qualified repair shop.

While driving antitheft light comes on and all the gauges go flat,car keeps runnig,want to disable system,not sure what to look for


Before doing something drastic ,have it checked out for DTC'S - diagnostic trouble codes . It may not be the anti-theft system ,gauges going flat would be more like a communication problem between modules . PCM / BCM / instrument cluster etc.. That also could cause theft light coming on . If your not sure what to look for ,take it to a ASE certified professional . You may render your vehicle useless if you don't know what your doing .
Serial Data Power Mode Master
On vehicles that have several control modules connected by serial data circuits, one module is the power mode master (PMM). On this vehicle, the PMM is the body control module (BCM). The PMM receives 3 discrete ignition switch signals to differentiate which power mode will be sent over the Serial Data circuits. The 3-wire Ignition Switch table below illustrates the state of these inputs in correspondence to the ignition switch position:
Serial Data Messages The modules that depend exclusively on serial data messages for power modes. stay in the state dictated by the last valid PMM message until they can check for the engine run flag status on the serial data circuits. If the PMM fails, the modules monitor the serial data circuit for the engine run flag serial data. If the engine run flag serial data is True, indicating that the engine is running, the modules fail-safe to RUN. In this state, the modules and their subsystems can support all operator requirements. If the engine run flag serial data is False, indicating that the engine is not running, the modules fail-safe to OFF-AWAKE. In this state, the modules are constantly checking for a change status message on the serial data circuits and can respond to both local inputs and serial data inputs from other modules on the vehicle.
Indicators and Warning Messages
Refer to Indicator/Warning Message Description and Operation .
Engine Coolant Temperature Gage
The instrument panel cluster (IPC) displays the engine coolant temperature as determined by the powertrain control module (PCM) or the engine control module (ECM). The IPC receives a serial data message from the PCM/ECM indicating the engine coolant temperature. The engine coolant temperature gage defaults to 38?°C (100?°F) if:
?€¢
The PCM/ECM detects a malfunction in the engine coolant temperature sensor circuit.


?€¢
The IPC detects a loss of serial data communications from the BCM.

Fuel Gage
The instrument panel cluster (IPC) displays the fuel level as determined by the powertrain control module (PCM) or the engine control module (ECM). The IPC receives a serial data message from the body control module (BCM) indicating the fuel level. The fuel gage defaults to E (empty) if:
?€¢
The PCM/ECM detects a malfunction in the fuel level sensor circuit.


?€¢
The IPC detects a loss of serial data communications from the BCM.

When the fuel level is less than 14 percent, the low fuel indicator illuminates.
Odometer
The instrument panel cluster (IPC) contains a season odometer and a trip odometer. Momentarily press the trip/reset switch in order to toggle between the season odometer and the trip odometer. Press the trip/reset switch for greater than 2 seconds, while the trip odometer is displayed, in order to reset the trip odometer. The odometer is calculated and stored electronically in the body control module (BCM). The BCM uses the vehicle speed information from the powertrain control module (PCM) to calculate the odometer. The odometer displays 'error' if an internal IPC memory failure is detected. The IPC stores a backup copy of the odometer value incase the IPC stops receiving a valid odometer value from the BCM.
Speedometer
The instrument panel cluster (IPC) displays the vehicle speed based on the information from the ECM/PCM. The IPC receives the vehicle speed information from the BCM via the serial data circuit. The speedometer defaults to 0 kmh (0 mph) when the following occurs:
?€¢
The powertrain control module (PCM) or the engine control module (ECM) detects a malfunction in the vehicle speed sensor circuit.


?€¢
The IPC detects a loss of serial data communication from the BCM.

Tachometer
The instrument panel cluster (IPC) displays the engine speed as determined by the powertrain control module (PCM) or the engine control module (ECM). The IPC receives a serial data message from the body control module (BCM) indicating the engine speed. The tachometer will default to 0 RPM if:
?€¢
The PCM/ECM detects a malfunction in the engine speed sensor circuit.


?€¢
The IPC detects a loss of serial data communication from the BCM.

Shift light flashing no OD Changed Trans ecm/pcm shift hold light button, coil No change. CYL missfire, 2 & 3 Diagnostics code on Trans is u0401 Invalid data received from ecm/pcm/a


Circuit Description
Modules that are connected to the shared communication circuits monitor for serial data communications during normal vehicle operation. Operating information and commands are exchanged among the modules. The modules have pre-recorded information about what messages are needed to be exchanged on the serial data circuits for each virtual network. The messages are usually supervised and some periodic messages are used by the receiver module as an availability indication of the transmitter module.

DTC U0401 TCM received invalid data from ECM
Conditions for Setting the DTC
The transmission control module (TCM) detects an invalid throttle position signal, engine speed signal and/or engine coolant temperature signal for more than 2 seconds.

Action Taken When the DTC Sets
• The TCM will store the DTC when a failure is detected on the first ignition cycle.
• The TCM will illuminate the HOLD lamp.
• The TCM can no longer determine the validity of any information it may or may not receive from the engine control module (ECM). Therefore the TCM substitutes default values for engine speed, throttle position, and other engine data signals.
• Transmission operation will be reduced, affecting shift points, torque converter clutch operation, and other driveability concerns.

Diagnostic Aids
• An intermittent malfunction may be caused by a fault in the electrical circuit. Inspect the wiring harness and the components for an intermittent condition. Refer to Intermittent Conditions in Engine Controls 1.6L.
• Repair any electrical circuit faults that were found. Refer to Wiring Repairs in Wiring Systems.
• Faulty ECM and/or TCM

I have a 2003 Malibu, 3.1 V6, 120K miles. Normally when I turn the ignition switch to on, all indicator warning lights and gas gauge work in the ip cluster. After a few seconds only the battery, check...


Well Gary , you should have it checked for DTC'S - diagnostic trouble codes . Not at a part's store , thier diagnostic tool only checks engine computer codes ! Your vehicle has a number of control modules , PCM/ECM - engine , BCM - body , ABS , Air bag , the instrument cluster has a microprocessor inside , an can set DTC'S as well. But the only way to read codes in most of these modules is with a professional type scan tool . The warning lights come on when you turn the key on as a bulb check an to let you know those systems are functioning . Could be your instrument cluster is defective or a communication network problem , do you know what a serial data bus or communication network is ? This is what the control modules share information on . Your 03 chevy has the IPC bus for data transfer from the BCM to the IPC . U codes are communication error codes .

Faulty electrical connections or wiring may be the cause of intermittent conditions. Refer to Testing for Intermittent Conditions and Poor Connections in Wiring Systems.
U2000
The IPC determines that the BCM transmitted data to the IPC is invalid for greater than 12 seconds. The IPC sends a message to the BCM via the SPI serial data in circuit indicating that invalid data was received.
U2001
The BCM determines that the IPC transmitted data to the BCM is invalid for greater than 5 seconds.
U2002
The BCM detects that the SPI serial data in circuit is less than 1.2 v for greater than 5 seconds.
U2003
The BCM detects that the SPI serial data in circuit is greater than 4.5 v for greater than 5 seconds.
U2004
The BCM detects that the SPI serial data out circuit is less than 1.2 v for greater than 5 seconds.
U2005
The BCM detects that the SPI serial data out circuit is greater than 4.5 v for greater than 5 seconds.
U2006
The BCM detects that the SPI serial data clock circuit is less than 1.2 v for greater than 5 seconds.
U2007
The BCM detects that the SPI serial data clock circuit is greater than 4.5 v for greater than 5 seconds.

Your vehicle also uses class 2 data bus .

Class 2 Serial Data Link
The class 2 serial data link allows the following modules to communicate with each other:
• The body control module (BCM)
• The electronic brake control module (EBCM)
• The integrated radio chassis (IRC)
• The powertrain control module (PCM)
• The Remote Control Door Lock Receiver (RCDLR)
• The inflatable restraint sensing and diagnostic module (SDM)
The class 2 serial data link allows a scan tool to communicate with the above modules for diagnostic and testing purposes.

I have a 2007 jeep compass...it stalled the other day. I took it to auto zone for a code reading...states code U1403. What is this and how can I fix it?


"U-codes" (codes beginning with a "U" prefix) are communications faults. Your vehicle is equipped with several computer modules which are all networked to gether on what is called the "Control Area Network" or "CAN". When one of the modules failes to communicate or if there is invalid data being transmitted by one of the modules, a U-code is stored in continuous memory in one or more of the other modules.

In your case, U1403 pertains to invalid or implausible data being recieved from the fuel level sensor by the Powertrain Control Module. Please note that this is NOT a fuel level sensor failure code and does NOT indicate faulty fuel level sensor circuits.

Theory of Operation

The TIPM receives a fuel level signal over CAN B from the Cluster. The TIPM transmits the fuel level message to the PCM over the CAN C bus.

The possible causes of this code are:
> Open or shorted CAN B circuit
> Instrument Cluster (CCN)
> Totally Integrated Power Module (TIPM)
> Powertrain Control Module (PCM)

To properly diagnose tis code, you must use a scan tool to access and verify data on all available modules. You must also determine if this is an active fault or an intermittent fault.

I don't see a fuel level signal problem at the PCM causing your engine to stall. However, the fuel level signal may be getting lost or "scrambled" due to a lack of communications between modules or a malfunctioning module. This could cause all sorts of problems (including stalling).

I would also like to add that my personal experience with this type of problem (communications faults) has taught me that the FIRST thing that should be done is a THOROUGH check of the BATTERY and CHARGING SYSTEM before attempting any communications diagnostics. If your battery is more than 4 years old, it is VERY LIKELY be the ROOT CAUSE of the problem. Computers tend to do all kinds of wierd things when they are not being fed properly.
