Lost current communication with fuel injector control module


Lost current communication with fuel injector control module ? Would you like to try and explain that a little better ? Lost communication with Engine computer PCM/ECM ? A scan tool won't talk with the PCM / ECM ? What type scan tool ? Can your scan tool talk with any other control module on the vehicle ? BCM , EBCM , SRS etc... if you know what those are ? Or current , are you talking about electrical current ? I know I only have thirty years experience as automotive Tech . I need terms that I can relate to .

I have a 2010 Chevy impala LS instrument cluster and it has a 20 pin plug I'm trying to figure out which wire's on the back of the cluster are for the speed sensor, rpm, gas, and temp wires.


Boy your way off base . All the gauges are inputs from the ECM - engine computer . The VSS - vehicle speed sensor , ETC - engine coolant temp sensor , sending unit in the fuel tank , All this sensors input the engine computer . The PCM then sends this info on the GMLAN serial data bus ,communications network . The Instrument cluster has a microprocessor inside that translates this info an controls the gauges. You probably have an instrument cluster problem or a communication network problem . Your best bet is to take your vehicle to the dealer or some other qualified repair shop. Need to have it checked for DTC'S - diagnostic trouble codes.
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 engine control module (ECM). The IPC receives a serial data message from the ECM indicating the engine coolant temperature. The IPC receives the coolant temperature information via serial data message from the body control module (BCM). The engine coolant temperature gage defaults to 60?°C (140?°F) or below if:
?€¢
The ECM detects a malfunction in the engine coolant temperature sensor circuit.

?€¢
The IPC detects a loss of serial data communications with the ECM.

?€¢
The IPC detects a loss of serial data communications with the BCM.
Fuel Gage
The instrument panel cluster (IPC) displays the fuel level as determined by the engine control module (ECM). The IPC receives a serial data message from the ECM indicating the fuel level percent. The body control module (BCM) sends the fuel level information from the ECM to the IPC via a serial data message indicating the fuel level percent. The fuel gage defaults to empty if:
?€¢
The ECM detects a malfunction in the fuel level sensor circuit.

?€¢
The IPC detects a loss of serial data communications with the ECM.

?€¢
The IPC detects a loss of serial data communications with the BCM.
When the fuel level is less than a pre-determined value, the low fuel indicator illuminates in the IPC.
Odometer
The vehicle odometer is calculated and stored electronically in the instrument panel cluster (IPC). The IPC contains a season odometer and trip odometer A or B. Momentarily press the trip/fuel button in order to toggle between the season odometer and the trip odometer. Press the set/reset button for greater than 0.25 seconds, while the trip odometer is displayed, in order to reset the trip odometer. The IPC displays the vehicle mileage and trip mileage as determined by the engine control module (ECM). The IPC calculates the mileage based on the serial data vehicle speed information from the ECM. The odometer will display 'error' if an internal IPC memory failure is detected. The odometer displays either miles or kilometers and can be set through the customization menu in the driver information center (DIC).
PRNDL Display
The instrument panel cluster (IPC) displays the selected gear position as determined by the engine control module (ECM). The IPC receives a serial data message from the ECM indicating the gear position. The PRNDL display blanks if:
?€¢
The ECM detects a malfunction in the transmission range switch circuit.

?€¢
The IPC detects a loss of serial data communications with the ECM.

?€¢
The IPC detects a loss of serial data communications with the body control module (BCM).
Speedometer
The instrument panel cluster (IPC) displays the vehicle speed as determined by the engine control module (ECM). The IPC calculates the mileage based on serial data vehicle speed information from the ECM. The IPC receives vehicle speed information from the body control module (BCM) via a serial data message. The speedometer defaults to 0 km/h (0 mph) if the IPC detects a loss of serial data communications with the ECM or BCM.
Tachometer
The instrument panel cluster (IPC) displays the engine speed as determined by the engine control module (ECM). The IPC receives a serial data message from the ECM indicating the engine speed. The IPC receives the engine speed information from the body control module (BCM) via a serial data message. The tachometer will default to 0 RPM if:
?€¢
The ECM detects a malfunction in the engine speed sensor circuit.

?€¢
The IPC detects a loss of serial data communications with the ECM.

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

Where is the Body Control Module located?


I'm just curious if your aware of the BCM function's on your vehicle an if you know what the gate way module is ? An do you know about serial data communication between modules ? An do you know what the power mode master is ? And do you know the BCM needs programming ?
The body control module (BCM) in this vehicle functions as a gateway or translator. The purpose of the gateway is to translate serial data messages between the GMLAN high speed buss and the GMLAN low speed buss for communication between the various modules. The gateway will interact with each network according to that network's transmission protocol.
One example of this necessary communication is the communication between the engine control module (ECM)/powertrain control module (PCM) which is high speed serial data and Theft Deterrent Module which is low speed serial data. If these modules can not exchange information, the vehicle will not start.
Communication between the BCM and a scan tool can be on the high speed GMLAN network or low speed GMLAN network. If one network is lost, the BCM can still communicate with the scan tool. A lost communication DTC typically is set in modules other than the module with a communication failure.

Intermintlly get these codes u110a, b1a28, u0126, u0141, u0151, no power, trans feels like it slips.


on the dash cluster display, sure.
these are not good codes to get..
what is best is the use a real OBD2 scan tool , and for sure
one the reads extended chrysler codes.
first U110a
U110A is a steering column control module lost communication
if you want to read the FSM on these codes, you can
and do all the tests it states there, to find true cause.
do you, , if not get the car scanned by a mechanic and diagnosed.
B1A28-ECM Mismatch With Skim 126. lost comms with steering angle sensor
141 lost comms with TIPM
151 lost comes with occupant restraint system.

the B1a28 is very serious. or just a loose connector.
the ECM and SKIM say the VIN number is lost. or was garbled
in the comm.s (noise)

2002 chevy avalanche dtc code u1064


lost communication with the BCM /body module - it means that the ECM / engine management module can't communicate with the body module, the one that controls the security in the key.
2 possible causes: either the body module has failed and it will have to be replaced and paired with the ECM (this is a job for a dealer or a well equipped shop) or you have a loose connection in the wiring. In that case and if you have some basic car electrical system knowledge you can check it yourself - remove some of the dash's and steering column's panel and check the connectors. Otherwise take it to a good repair shop.

What is code B2799


This Diagnostic Trouble Code (DTC) is output when the Engine Control Module (ECM) detects errors in communication between the Transponder Key Electronic Control Unit (ECU) assembly and the ECM, or in the communication lines. This DTC is also output when an engine start is attempted while the ECU communication ID between the transponder key ECU assembly and the ECM is different.
Possible causes Faulty Key Faulty transponder key amplifier Faulty Transponder Key Electronic Control Unit (ECU) Transponder key amplifier wire harness Faulty Engine Control Module (ECM)

I got a code from auto zone that is i believe UO 101 AND UO105 OR UA101 AND UA105 WHAT do these codes stand for


These codes are communications code errors:

The UO101 is a transmission communication error: poor communication to your transmission ECM / computer

The UO105 is a fuel injection communication error: Poor communication to your fuel injector ECM/ computer.
