2003 CTS drivers seat stuck in closest position to the steering wheel. All other functions of the seat work (lumbar & recline)


Don't know how you read these codes but their is no H in back .
Factory service repair info.
DTC B3832 or B3833
Express Up operation of the front door power windows is monitored and controlled by the front door modules, the window sensors, and the 4 connecting circuits. Each front door window motor has a window sensor mounted to it. The driver door module (DDM) and the passenger front door module (PFDM) each supply battery positive voltage and ground to power their respective window sensors. Each door module communicates with its sensor via a power window high speed serial data circuit, and a power window low speed serial data circuit. The window sensor detects differences in the window motors electrical pulses to determine if there is an obstruction to the travel of the window glass. The door modules use the information generated by the sensors to disable the Express Up movement of a window, or reverse the direction of travel, in the event that a passenger, or other obstacle, has become trapped in it.
The power window low speed serial data circuit is a unique 2-way serial data link between the door module and its sensor. The actual position of the window glass, in relationship to the distance traveled by the window, is communicated via this circuit, as well as state-of-health messages and the direction in which the window is traveling.


DTC B3832 may be set and the Express Up function disabled if the vehicle or the door module has recently lost power for any reason. You should first attempt to re-initialize the Express Up function. Refer to Window Motor Programming - Express Function .
If DTC B3832 is accompanied by DTC U1714, utilize the DTC U1714 or U1716 diagnostic table before using this table. Refer to DTC U1714 or U1716 .

DTC B1420
Battery positive voltage is supplied at all times to the seat adjuster switch and the memory seat module (MSM) through the same circuit. The MSM uses this battery voltage input to determine if battery positive voltage is applied to the seat adjuster switch.
DTC B1825, B1850, B1860, B2355, B2365, or B2375
Circuit Description
The position sensor that sets this DTC is attached to the seat directional motor. It receives a 5 volt reference and low reference from the memory seat module (MSM). The sensor sends a voltage signal that varies with the movement of the seat through the signal circuit to the MSM. Then based on this voltage signal, the MSM determines the position of the seat.

Install a scan tool.
Turn ON the ignition, with the engine OFF.
With a scan tool, observe the appropriate Sensor parameter in the Memory Seat Module Sensor data list.
Does the scan tool indicate that the Sensor parameter is within the specified range?
0.25-4.75 V

Sure you can move the seat back . Connector # 3 at the MSM ,pin's S & N - lite green & tan wires . Give a ground to one an B+ to the other ,if it moves in wrong direction switch the wiring around ..

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.

2003 trailblazer codes U-1000, B- 1850, Y- 1160, what do they mean?


Don't see these too often, must of been a dealer or a good mechanic with some expensive equipment....

U1000 is loss of communication with an unknown module...could be any module like TCCM.
B1850 is Drivers Lumbar Horizontal sensor Circuit Malfunction...in your seat.
Y1160, I have no clue what this is.

I would take it to a mechanic that has a Tech II (or equivalant) diagnostic machine, this will pinpoint your problem with at least the U1000...will show which module is not communicating. Would be able to tell you what the Y1160 is also. Good luck!

Trouble code u1000 on nissan titan


DTC (Diagnostic Trouble Code) U1000 is a problem with the CAN communication line.
CAN (Controller Area Network) is a serial communication line for real time application. It is an on-vehicle multiplex communication line with high data communication speed and excellent error detection ability. Many electronic control units are equipped onto a vehicle, and each control unit shares information and links with other control units during operation

This DTC sets under the following conditions:

The ECM (Engine Control Module) has lost communications with one or more of the onboard control units for a specified amount of time.

To diagnose this code you must scan all the other modules to see if they can communicate with the scanner. If all the modules are able to communicate with the scanner then the problem is intermittent and can be very hard to find. If you have one or more modules that fail to communicate then the problem is the data line to that (those) module(s).

Obd code U1041


Codes U1XXX (where XXX stands for several possible numerical digits, 001 - 254) are communications fault codes. The first part (U1) tells you that there is a communication problem with one of your many onboard control modules. The second part (XXX) or in your case, (041) tells you which module is not communicating. It can vary from year to year, model to model. so without knowing the year and model of the vehicle we are talking about, I cannot tell you which one.

In any case, there is a module that is not communicating with the other modules that are sharing information through the Class 2 serial data circuit. One module uses U-codes to tell on the other modules. For instance, If you got the U1041 code out of scanning the Engine Control Module, you can bet that the Engine Control Module is not having a problem communicating. If it was, you would get a non-communication fault from your scan equipment and the ECM would not tell you anything. Instead, the ECM is telling on the module that is not communicating properly .

I like to call these codes the 1-800 codes...THE PHONE LINE IS DOWN... lol ;)
