The switch that failed and generated this diagnostic trouble code (DTC) is part of the driver door switch. This module contains a microprocessor which takes the ground signal generated by this switch and assigns a digital message to the switch signal. The driver door switch then sends this message over a simple bus interface (SBI) link to the driver door module (DDM).
The DDM must be powered for this DTC to set.
If the driver door module (DDM) receives the message that the switch is closed for more than 30 continuous seconds the DDM sets this DTC.
The driver door switch assembly does not send a new lockout ON/OFF message until the DTC is cleared and the switch is re-activated. The function defaults to the last valid state of either locked out or not locked out. The indicator lamp state corresponds to the last valid state, ON for locked out, OFF for not locked out.
The DDM clears this DTC when the switch message indicates a change of states.
The numbers below refer to the step numbers on the diagnostic table.
Step | Action | Yes | No |
---|---|---|---|
1 | Did you perform the Door Systems Diagnostic System Check? | ||
Does the scan tool display Inactive? | |||
3 |
Does the Window Lockout Sw. parameter change state? | ||
4 |
Does the scan tool indicate the Inactive state? | ||
5 | Inspect for poor connections/terminal tension at the driver 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? | ||
6 | Inspect for poor connections/terminal tension at the driver door switch assembly (DDSA) harness connector. Refer to Testing for Intermittent Conditions and Poor Connections and Connector Repairs in Wiring Systems . Did you find and correct the condition? | ||
7 | Replace the driver door module. Refer to Door Control Module Replacement . Did you complete the replacement? | -- | |
8 | Replace the driver door switch assembly (DDSA). Refer to Front Door Switch Replacement . Did you complete the replacement? | -- | |
9 |
Does the DTC reset? | System OK |
