Why do I have all these codes on in my 04 Pontiac grand prix gt. U1000,u1300,u1016,u1064,u1096


There is a Pontiac Technical Service Bulletin addressing your exact issue, right down the the same exact codes you are getting. Here is the information I gathered and I will place a link to the page where I found it. You will need to scroll down the list of TSBs to find your specific one. Apparently this is a problem for the Grand Prix.

Here is the basic data:

TSB Number: 0308116001 NHTSA Number: 10002880 TSB Date: February 1, 2004 Date Added to File: September 30, 2003 Failing Component: Electrical System Summary: Diagnostic trouble code (DTC) U1000, U1016, U1064, U1096 or U1305 set in error. This bulletin replaces previous bulletin dated 06/01/2003.

Code u1000 code p0105 u1152


Codes U1000 & U1152 are related to the digital data bus communications, U1152 is specific for the HVAC control unit data bus. troubleshooting this will require a Tech II scan tool.
P0105 is related to the MAP sensor circuit.

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.

1999 pontiac grand am not charging


Diagnostic Test Code (DTC) U1000 has a generic description of "Class 2 Serial Data Link Malfunction".
DTC U1064 has a description of "Loss Of Communication With Body Control Module (BCM)"
These codes can be caused by a malfunctioning charging system and should be ignored for now.

DTC P0562 has a description of "System Voltage Low". So this code basicly is only verifying that you indeed have a no-charging problem and that the other codes are most likely also caused by low system voltage.

Although these codes do verify that you have a charging system problem, they are useless in finding out exactly what is wrong with your charging system.

You will need a scan tool that is capable of 2-way communications with the PCM and performing system tests. you will also need a digital multimeter to test the system as you command the generator circuits on with the scanner. If your scanner can do this, let me know and I will get you the troubleshooting instructions for your vehicle. Otherwise, you will have to take it to someone who is properly equipped to diagnose your charging system.

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
Action
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.
