PDM-41

PDM-41-LIN OPEN OR SHORT TO BATTERY





For a complete wiring diagram Consult Diagrams/Electrical

- When Monitored:
Whenever battery power is supplied to the LIN module (on the window motor).

- Set Condition:
If the LIN voltage toggles too high or too low for over five seconds, this code will set.





Diagnostic Test

1. DTC PRESENT
Turn the ignition on.
With the scan tool, erase DTCs.
Cycle the ignition switch from Off to Run.
Operate the passenger window switch in all positions several times.
With the scan tool, read DTCs.
Does the scan tool display 41-LIN OPEN OR SHORT TO BATTERY?

Yes

- Go To 2

No

- The condition that caused this code to set is not present at this time. Using the wiring diagram/schematic as a guide, inspect the wiring and connectors.
- Perform the BODY VERIFICATION TEST - VER 1. Body Verification Test.

2. (A916) FUSED B+ CIRCUIT OPEN




NOTE: Ensure Fuse No. 10 is good and in place before proceeding.

Turn the ignition off.
Disconnect the Passenger Window Motor connector.
Turn the ignition on.
Measure the voltage between the (A916) Fused B+ circuit and ground in the window motor connector.
Is the voltage above 11.5 volts?

Yes

- Go To 3

No

- Repair the (A916) Fused B+ circuit for an open.
- Perform the BODY VERIFICATION TEST - VER 1. Body Verification Test.

3. (Z822) GROUND OPEN




Using a 12-volt test light connected to 12-volts, test the (Z822) Ground circuit.
Does the test light illuminate brightly?

Yes

- Go To 4

No

- Repair the (Z822) Ground circuit for an open.
- Perform the BODY VERIFICATION TEST - VER 1. Body Verification Test.

4. (D505) LIN BUS CIRCUIT SHORT TO VOLTAGE




Measure the voltage between the (D505) LIN Bus circuit and ground.
Is the voltage above 8.5 volts?

Yes

- Go To 5

No

- Go To 6

5. DRIVER DOOR MODULE




Turn the ignition off.
Disconnect the Passenger Door Module C1 connector.
Turn the ignition on.
Measure the voltage between the (D505) LIN Bus circuit and ground in the window motor connector.
Is there any voltage present?

Yes

- Repair the (D505) LIN Bus circuit for a short to voltage.
- Perform the BODY VERIFICATION TEST - VER 1. Body Verification Test.

No

- Replace the Passenger Door Module.
- Perform the BODY VERIFICATION TEST - VER 1. Body Verification Test.

6. (D505) LIN BUS CIRCUIT OPEN




Measure the voltage between the (D505) LIN Bus circuit and ground.
Is the voltage between 7.7 volts and 8.4 volts?

Yes

- Replace the Passenger Window Motor (regulator).
- Perform the BODY VERIFICATION TEST - VER 1. Body Verification Test.

No

- Go To 7

7. (D505) LIN BUS WIRE OPEN




Turn the ignition off.
Disconnect the Passenger Door Module C1 connector.
Measure the resistance of the (D505) LIN Bus circuit between the window motor connector and the PDM C1 connector.
Is the resistance below 2.0 ohms?

No

- Repair the (D505) LIN Bus circuit for an open.
- Perform the BODY VERIFICATION TEST - VER 1. Body Verification Test.

Yes

- Replace the Passenger Door Module.
- Perform the BODY VERIFICATION TEST - VER 1. Body Verification Test.
