2004 Suzuki Verona 2.5 data link connector wiring diagram no pcm communication

Question edited for clarity

The ECM and the engine need to be from the same vehicle and then the ECM needs programming with your VIN Number and your mileage.

Code U0100 What Does the U0100 Code Mean? DTC U0100 stands for "Lost Communication with ECM/PCM 'A. '" It is triggered once there is a loss of communication between your PCM and a particular module. Once this happens, the vehicle may shut off and it may not restart unless you address the issue triggering the code.May 2, 2021

not reason why stated???????? fun, ?
the fuel pressure is over 60 psi, try not to get a bath in fuel.
right? there is no reason to this. (unless tank contam)
you can hot wire a pump with rear connectors pulled first
then measure rail pressures., (over 6 test there)

rule 1 , pump is fuel lubricated
rule 2 pump is fuel cooled.
do not violate 1 or 2, or you will burn it up., i promise!
the FSM is only 4 bucks. posted over 100 times here now.

why send a link to a GM car? odd that.
to make links work have and enter key before and after the link
like mine..

ill actual look for you.
there is level sender and temperature pins and pump
the connector is C901
pins 3 and 8 are pump and is polarized
so dont power it backwards or boom.






pump


level and (pressure transducer)

go to suzuki yet?, in usa they are IMPLODED, (bugged out)
Verona? 2004
here is the EX model
if confused call them. and give VIN
and they can in fact match VIN to any part. you want
in USA. (i cant do non usa ever)

You can not reset a BCM ! If there is a problem with one of the systems associated with the BCM . It has a DTC stored in memory ! Besides your vehicle does not have a BCM ! It has three modules !
The body control system consists of the following 3 modules:
?€¢
The Dash Integration Module (DIM)

?€¢
The Instrument Panel Module (IPM)

?€¢
The Rear Integration Module (RIM)

Each of the 3 body control modules integrate a number of functional systems under the control of a single module. Each module is connected to the Class 2 serial data circuit, many of the control functions are implemented by Class 2 messages.
Dash Integration Module (DIM)
The various DIM input and output circuits are described in the corresponding functional areas as indicated on the DIM electrical schematics.
The DIM functions include the following:
?€¢
Class 2 communication requiring DIM interaction.

?€¢
Control of exterior lamps.

?€¢
Control of front fog lights.

?€¢
Control of the headlights.

?€¢
Headlamps on with wiper input.

?€¢
Hood ajar switch input w/export.

?€¢
Horn relay control.

?€¢
Interior lamps incandescent dimming.

?€¢
Low side temperature for HVAC compressor.

?€¢
Power moding control over Class 2 serial data circuit.

?€¢
Reverse lockout solenoid control.

?€¢
Steering wheel controls input.

?€¢
Storage of the clock settings and, sending a message out on the class 2 serial data circuit in response to requests from other modules.

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 DIM. The PMM receives 4 signals from the ignition switch.
To determine the correct power mode the PMM uses the following circuits:
?€¢
Accessory voltage

?€¢
Ignition 1 voltage

?€¢
Ignition 3 voltage

?€¢
Off/Run/Crank voltage

You have no idea what your getting yourself into when messing with these thing's ! You mess with the wrong thing an your vehicle will never work again , not for you anyway ! These modules all communicate together on a class 2 serial data network ,
The data link connector (DLC) allows a scan tool to communicate with the class 2 serial data line. The serial data line is the means by which the microprocessor-controlled modules in the vehicle communicate with each other. Once the scan tool is connected to the class 2 serial data line through the DLC, the scan tool can be used to monitor each module for diagnostic purposes and to check for diagnostic trouble codes (DTCs). Class 2 serial data is transmitted on a single wire at an average of 10.4 kbps. This value is an average; class 2 uses a variable pulse width modulation to carry data and depending on the message it may operate faster or slower. The bus will float at a nominal 7 volts during normal operation. Each module can pull this lower during the transmission. The bus is not at battery positive voltage or ground potential during normal operation. When the ignition switch is in RUN, each module communicating on the class 2 serial data line sends a state of health (SOH) message every 2 seconds to ensure that the module is operating properly. When a module stops communicating on the class 2 serial data line, for example, if the module loses power or ground, the SOH message it normally sends on the data line every 2 seconds disappears. Other modules on the class 2 serial data line, which expect to receive that SOH message, detect its absence; those modules in turn set an internal DTC associated with the loss of SOH of the non-communicating module. The DTC is unique to the module which is not communicating; for example, when the inflatable restraint sensing and diagnostic module (SDM) SOH message disappears, several modules set DTC U1088. Note that a loss of serial data DTC does not normally represent a failure of the module that set it.
On some vehicles, if the powertrain control module (PCM) is unable to communicate with the vehicle theft deterrent (VTD) system after the vehicle has started, the PCM will consider the VTD system to be malfunctioning. The PCM will enter a fail enable state and will command the security indicator to illuminate. When the PCM is in a fail enable state, the vehicle will NOT stall or stop running. If the PCM is in a fail enable state when the ignition is switched OFF, the PCM will remain fail enable until communications with the VTD system has been restored. When the PCM is in a fail enable state, the VTD system is NOT active and the vehicle will start. This feature is NOT available on all GM vehicle lines.

there it is.

double posted, backup one.

You better read up on class 2 serial data communication networks . Does supply ACC voltage to anything . Your vehicle has many different control modules , PCM / ECM , air bag , ABS , BCM instrument cluster ,an the radio an some others . If you mess with or ground this wire your vehicle will not start or do anything .

You need a interface module for your radio to work . Go to a professional installer place an talk with them . Your vehicle may not have all of these modules , but most .

GM Class II RDS Radio 12V Ignition Wiring

p1670 is a communications error between abs module and ecm- ecm does a communications check in first 5 seconds of cycling key from off to on/start. Can be affected by other modules on network, possible causes include but are not limited to bad abs module, wiring, connectors, terminals in connector, chafing of wiring,possible software issue. Recommend clearing codes and waiting for it to become a hard code( sets code EVERY time key is cycled on ) in order to pinpoint- very elusive problem unless setting a hard code
