Circuit Description
The switch that failed and generated this diagnostic trouble code (DTC) is part of the DDM or the PDM. When a switch is activated, the DDM/PDM then either actuates the appropriate component or sends a message over the serial data link to the appropriate module to actuate the appropriate component.
Conditions for Running the DTC
| • | System voltage is between 9.0 and 16 volts. |
| • | Ignition switch is in the ON position. |
Conditions for Setting the DTC
If the DDM or the PDM receives multiple inputs from a single switch at the same time for more then 160 milliseconds, the DDM/PDM sets the DTC. The following switches will set this DTC:
| • | The door lock switch |
| • | The power window switch |
| • | The window lockout switch |
| • | The mirror select switch |
Action Taken When the DTC Sets
The DDM/PDM ignores the continuous inputs from the switch. The DDM/PDM will not respond to the invalid inputs as a command for the component. The DDM/PDM will respond to all other valid switch inputs.
Conditions for Clearing the DTC
When the switch input status changes, the DDM/PDM clears this current DTC and stores the DTC as a history DTC. The history DTC will clear either after 50 ignition switch cycles without a repeated failure or in response to a scan tool command.

1 | Did you perform the Door Systems Diagnostic System Check? | Go to Step 2 | |
2 |
Does the scan tool display an inactive state? | Go to Step 3 | Go to Step 4 |
3 |
Does the switch parameter change state? | Go to Testing for Intermittent Conditions and Poor Connections in Wiring Systems | Go to Step 4 |
4 | Inspect for poor connections/terminal tension at the door module harness connector. Refer to Testing for Intermittent Conditions and Poor Connections and Connector Repairs in Wiring Systems. Did you find and correct the condition? | Go to Step 6 | Go to Step 5 |
5 | Replace the appropriate door module. Refer to Door Lock and Side Window Switch Replacement - Driver Side or Door Lock and Side Window Switch Replacement - Passenger Side . Did you complete the replacement? | Go to Step 6 | -- |
