For a complete wiring diagram, refer to the Wiring Information.

- When Monitored:
Continuously.

- Set Condition:
The Door Module receives a conflicting input from the (G200) Memory Select Switch Mux circuit for more than 30 seconds.





1. INSPECT MEMORY SET SWITCH FOR DAMAGE
1. Turn the ignition off.
2. Inspect the Memory Set switch for damage.

Is the switch damaged?

Yes

- Replace the Memory Set switch.
- Perform the BODY VERIFICATION TEST. Body Verification Test.

No

- Go To 2

2. INSPECT FOR OBJECT OR SUBSTANCE CAUSING MEMORY SET SWITCH TO STAY OR STICK IN A PUSHED POSITION
1. Inspect the Memory Set switch for anything that would cause it to stay or stick in a pushed position.

Is anything present that would cause the Memory Set switch to stay or stick in a pushed position?

Yes

- Repair as necessary.
- Perform the BODY VERIFICATION TEST. Body Verification Test.

No

- Go To 3

3. TEST FOR INTERMITTENT CONDITION
1. Turn the ignition on.
2. Using a scan tool, record and erase Diagnostic Trouble Codes (DTCs).
3. Press the Memory Set switch several times in all positions.
4. Cycle the ignition from on to off three times.
5. Turn the ignition on then wait 30 seconds.
6. Using a scan tool, read DTCs.

Is the DTC active?

Yes

- Go To 4

No

- The conditions that caused this code to set are not present at this time. Verify seat harness is routed correctly. Using the wiring diagram/schematic as a guide, inspect the wiring and connectors. Attempt to reproduce condition by adjusting the seat.
- Perform the BODY VERIFICATION TEST. Body Verification Test.

4. CHECK MEMORY SET SWITCH FOR A SHORT TO GROUND




1. Using a scan tool, erase DTCs.
2. Turn the ignition off.
3. Disconnect the Memory Set switch connector.
4. Cycle the ignition three times.
5. Turn the ignition on and then wait 30 seconds.
6. Using a scan tool, read DTCs.

Is the same DTC active?

Yes

- Go To 5

No

- Replace the Memory Set switch.
- Perform the BODY VERIFICATION TEST. Body Verification Test.

5. CHECK (G200) MEMORY SELECT SWITCH MUX CIRCUIT FOR A SHORT TO GROUND




1. Disconnect the Door Module C5 connector.
2. Measure the resistance between ground and the (G200) Memory Select Switch Mux circuit at the Memory Set switch connector.

Is the resistance below 10K Ohms?

Yes

- Repair the (G200) Memory Select Switch Mux circuit for a short to ground.
- Perform the BODY VERIFICATION TEST. Body Verification Test.

No

- Go To 6

6. CHECK (G200) MEMORY SELECT SWITCH MUX CIRCUIT FOR A SHORT TO THE (G920) MEMORY SELECT SWITCH RETURN CIRCUIT




1. Measure the resistance between the (G200) Memory Select Switch Mux circuit and the (G920) Memory Select Switch Return circuit at the Memory Set switch connector.

Is the resistance below 10K Ohms?

Yes

- Repair the (G200) Memory Select Switch Mux circuit for a short to the (G920) Memory Select Switch return circuit.
- Perform the BODY VERIFICATION TEST. Body Verification Test.

No

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