What does code po700 mean on a cadillac cts 2006


From:


P0700 is an informational code only. It doesn't point to a direct fault in the engine, only a general fault in the transmission. More diagnosis is necessary to identify what the transmission fault is. This requires a scan tool that will communicate with the transmission module.
More often then not, the cause of this code is that there is a transmission problem of some kind. The TCM detected the problem and set a code. P0700 means that a fault code is stored in the TCM. However this doesn't rule out the possibility of a failed PCM or TCM (unlikely).
For a P0700 the only real solution is to acquire a scan tool that will communicate with the transmission control module. Extracting this code from the TCM will be the first step in repairing the fault in the transmission.

I have a problem in shift from 2nd to 3d trans in my car (2003 Jeep Grand Cherokee)


You need to BEGIN diagnosis by scanning your engine and transmission control module(s) for possible Diagnostic Test Codes (DTCs) (Also commonly called "fault codes")

My 1999 Mitshubishi Mirage neutral light comes on while i'm driving and the car jerks when i put it in gear


The 1st thing you must have done here is to have the electronic control module (called the "TCM") for the transmission checked for fault codes, the transmission is computer controlled through electric solenoids and other sensors whose input is used to provide proper shifting based on load, engine temperature, vehicle speed and transmission fluid temperature. Once the codes are checked you proceed with diagnosis based on that information. This test takes a special high end electronic scan tool.

Tahoe reset


What are you wanting to reset? What needs to be done is diagnosis of the stalling problem. This can be caused by many things. It could be the ignition system, the fuel system or even the vehicle security system malfunctioning. I would begin diagnosis by scanning your onboard computer network for possible fault codes and go from there.

Diagnostic Test Modes Without Scan Tool
Two mode options are available under the diagnostic test modes:
  • user mode.
  • diagnosis mode.
The ignition switch is used to alternate from one mode to another.
Diagnosis Mode
The diagnosis mode will display any fault present in the system. The SRS will not enter diagnosis mode if no malfunction is detected.
User Mode to Diagnosis Mode
NOTE: The SRS will not enter diagnosis mode if no fault is detected in user mode.
  1. Ignition switch to ON.
  1. After the air bag warning indicator lights for seven seconds, set ignition switch to OFF within one second.
  1. Wait more than three seconds.
  1. Repeat steps 1 through 3 three times.
  1. Ignition switch to ON.
Diagnosis Mode to User Mode — After Repair
  1. Ignition switch to OFF for at least one second.
  1. Ignition switch to ON.
Diagnosis Mode to User Mode — During Diagnosis
NOTE: If switch from Diagnosis Mode to User Mode is required while diagnosing a fault, carry out the following procedure.
  1. Ignition switch to ON.
  1. After the air bag warning indicator lights for seven seconds, set ignition switch to OFF within one second.
  1. Wait more than three seconds.
  1. Repeat steps 1 through 3 three times.
  1. Ignition switch to ON.
Clearing Lamp Fault Codes
NOTE: Lamp fault codes must be cleared from memory before proving out the system.
NOTE: When a new RCM is installed, the air bag warning indicator will operate in user mode. Switching to diagnosis mode is not required.
To clear lamp fault codes after a repair, carry out the procedure to switch from diagnosis mode to user mode. Once in the user mode, the lamp fault codes will be cleared from memory.
Lamp Fault Codes
If the air bag diagnostic monitor detects a current fault, the fault code will be displayed with a flashing sequence of the air bag indicator. The fault code consists of:
  • A start signal to indicate the beginning of a fault code.
  • A number of flashes indicating the particular code that has been set.
The start signal:
  • begins with two seconds off.
  • two seconds on.
  • off.
  • one second on.
  • two seconds off.
Following the start signal, if any current fault is detected, the fault code will be displayed. The fault code:
  • is a series of half second flashes of the air bag indicator.
  • is followed by the start signal.
The start signal and the code for any current fault will repeat until the ignition is switched off or the air bag diagnostic monitor is switched to the user mode.
Inspection and Verification
  1. Verify the customer concern by checking the air bag indicator in the instrument cluster. Refer to Prove Out in this section.
  1. Visually inspect for obvious signs of mechanical and electrical damage using the following chart.


Visual Inspection Chart Mechanical Electrical
  • Damaged air bag diagnostic monitor bracket
  • Open fuse
  • Damaged wiring harness
  • Loose or corroded connectors
  • Circuitry open or shorted
  • Damaged shorting bars

  1. If the concern is not visually evident, enter the system Diagnosis Mode.
  1. If no DTCs are displayed in the Diagnosis Mode, proceed to the Symptom Chart in this section.
  1. If DTCs are retrieved, proceed to the Air Bag Diagnostic Monitor Fault Code Table in this section.
