Circuit Description
The BCM door lock ground (Ground 2) circuit provides ground for the door lock actuators.
Conditions for Running the DTC
The BCM Electronics ground must be connected to ground.
Conditions for Setting the DTC
| • | The BCM detects that the door lock ground (Ground 2) circuit is greater than 8 volts for longer than 0.3 seconds. |
| • | The BCM detects that the door lock ground (Ground 2) circuit is open for longer than 0.3 seconds. |
Action Taken When the DTC Sets
The BCM stores DTC B1349 in memory.
Conditions for Clearing the DTC
| • | A current DTC B1349 will clear if the BCM no longer detects the fault. |
| • | A history DTC B1349 will clear after 100 consecutive ignition cycles if the condition for the malfunction is no longer present. |
| • | A scan tool may be used to clear the DTC. |
Diagnostic Aids
| • | If the DTC B1349 is a history DTC, the fault may be intermittent. Refer to Testing for Intermittent Conditions and Poor Connections in Wiring Systems. |
| • | The following conditions may cause an intermittent malfunction to occur: |
| - | An intermittent open in the door lock ground (Ground 2) circuit. |
| - | The BCM is intermittently open internally. |
Test Description
The number(s) below refer to the step number(s) on the diagnostic table.
Step | Action | Value(s) | Yes | No |
|---|---|---|---|---|
1 | Did you perform the Body Control Module Diagnostic System Check? | -- | Go to Step 2 | |
2 |
Does the scan tool display Present for the parameter? | -- | Go to Diagnostic Aids | Go to Step 3 |
Test the ground circuit in the previous step for an open. 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 4 | |
4 | Inspect for poor connections at the harness connector of the Body Control Module. 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 |
Did you complete the repair? | -- | Go to Step 6 | -- |
6 |
Does the DTC reset? | -- | Go to Step 2 | System OK |
