Circuit Description
The rear integration module (RIM) monitors the voltage input of the hood open switch signal circuit and the hood open closed switch signal circuit. During proper operation, the 2 separate voltage signals at the RIM should never be the same voltage with the hood opened or closed. If the 2 voltage signal should have the same voltage value DTC B3006 will set.
DTC Descriptor
This diagnostic procedure supports the following DTC:
DTC B3006 Hood Ajar Circuit
DTC Symptom | DTC Symptom Descriptor |
|---|---|
5A | Plausibility Failure |
Conditions for Running the DTC
This DTC shall run when the Run/Crank Relay is enabled.
Conditions for Setting the DTC
If both the hood open switch signal circuit and the hood closed switch signal circuit are simultaneously in a high or low voltage state.
Action Taken When the DTC Sets
| • | Remote start functions will be disabled. |
| • | The hood ajar switch inputs will be ignored by content theft deterrent (CTD). |
Conditions for Clearing the DTC
The DTC will clear when conditions for setting the DTC are no longer present
