I have a Pontiac grand am 2000 I'm getting codes u1000 and u1064


U1000 means modules on the data line have stopped seeing communication with a module. U1064 is a communication code for the BCM. It may be faulty or not communicating for some reason. If it has been changed it needs to be programmed.

My 2003 Cadillac deville system electric is on now my brake light don't work or my window won't let up


SERVICE ELECTRICAL SYS - 106
The IPC illuminates the SERVICE ELECTRICAL SYS -- 106 message in the DIC when one of the following conditions exist:
?€¢
The dash integration module (DIM) detects a malfunction that is related to the ignition switch.


The IPC receives a class 2 message requesting illumination from the DIM.


?€¢
There is a powertrain related code present.


The IPC receives a class 2 message requesting illumination from the PCM. 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


Your having a module problem , need to have it checked for DTC'S . Dealer only one for that !

Check engine light codes


the c0899 is a low battery voltage and the u1064 means communication is lost with the bBody Control Module. The u1026 is also a communication problem and the p0449 is an emissions problem, around the venting of the fuel tank. Sounds like several different unrelated problems.

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 do these check engine light codes mean? I can't find them anywhere. B0040, B0099, U1026, U1064


As previous post stated you may have data cable unhooked somewhere.
B0040- Second Row Right Frontal Stage 2 Deployment Control (Subfault)
B0099- Right Frontal Restraints Sensor 2 (subfault)
U1026- Loss of Active Transfer Case Control Module Communications.
U1064- I do not have a listing for that code on hand. May be able to obtain it when I get to my shop tomorrow.

What is code u1000 and u1064


U1064 Lost Communication With Body Control Module (BCM)

U1000 Class 2 Data Link Malfunction

Do your door locks, power windows, etc. still work? I'm assuming this is for a Pontiac since that is the picture that comes up with your question. I'm still getting used to this new site.

I took my 2004 Blazer to get a diagnostic check. Two codes came uo U1064 and U1096. What are some solutions to fix this problem? The instrument panel lights stay on after the car has been started and will...


U1064 - Loss of Communications with DIM (Dash Integration Module)
Here is some TSB

Refer to Data Link Connector (DLC) Schematics

Circuit Description
The class 2 serial data line communicates information between modules. Each module connected to the serial data line is assigned a recognition code, or address. This code is used in order to identify which modules are communicating. Modules communicate with each other by periodically sending state of health (SOH) messages. When the ignition switch is in RUN, each module communicating on the serial data line sends a SOH message every 2 seconds. This ensures that the system is operating properly. When the dash integration module (DIM) stops communicating on the class 2 serial data line, the SOH that is normally sent on the serial data line every 2 seconds disappears. The module, which expects to receive that message, detects the absence of the message. The module in turn sets DTC U1064 associated with the loss of SOH of the DIM.

Conditions for Setting the DTC
The module does not receive a state of health (SOH) message back from the DIM. The module retries the request 3 times, and then sets DTC U1064.

This DTC only sets if U1300 or U1301 is not current.
Action Taken When the DTC Sets
DTC U1064 is stored in the module.

The module uses the default values for the initialization data. This DTC does not cause driver warning message to appear.

Conditions for Clearing the DTC
This DTC clears (status changes from current to history) under any of the following conditions:
The module detects a state of health message from the DIM.
At each ignition cycle.
A history DTC clears after 50 consecutive ignition cycles if the conditions for setting the DTC are no longer present.
Current and history DTCs may be cleared using a scan tool.

Diagnostic Aids
DTC U1064 does not normally represent a failure within the module.
When loss of class 2 serial data communication DTCs (DTCs with the letter U as the prefix) are stored as history DTCs, know all possible serial data DTCs set in each module before diagnosing the serial data line.

If U1064 is stored in the module memory, inspect for the same DTC stored in other modules capable of storing this DTC.
If the DTC is a history DTC, the problem may be intermittent.

Test Description: The numbers below refer to the step numbers on the diagnostic table:

U1064 is the result of loss of communication with the dash integration module (DIM). Note that other modules on the class 2 serial data line may also set U1064 if the DIM is not communicating with the serial data line.

Clear all DTCs after the repair procedure is complete.
Step

Value(s)
Yes
No

1
Did you perform the Data Link Communications Diagnostic System Check?
--
Go to Step 2
Go to Diagnostic System Check - Data Link Communications

2
Use a scan tool in order to attempt the establish communication with the dash integration module (DIM).

Does the scan tool communicate with the DIM?
--
Go to Step 3
Go to Diagnostic System Check - Body Control System in Body Control System.

3
Inspect and repair the class 2 serial data line CKT 1807 (PPL) for intermittent connections. Refer to Intermittents and Poor Connections Diagnosis in Wiring Systems.

Is the repair complete?
--
Go to Step 4

4
Turn off the ignition switch.
Reconnect or install any connectors or components that were disconnected or removed.
Turn on the ignition switch.
Clear any DTCs.
Is the repair complete?



U1096 - Loss of Communications with IPC

The computers on the Chevy require a certain voltage to operate and if the voltage drops below a preset limit then it will tripper a loss of communication with the other modules, this drop in voltage happens when the car is started and the draw on the starter uses a large amount of amperage. I suggest to check power/ground in the instrument cluster and if good do a resistance test on Data wire.

If your car is not experincing any messages like "service vehicle soon" and no warning lights are illuminating then disregard these codes.


Hope helps.
