B182C-ALL DOOR LOCK CONTROL CIRCUIT PERFORMANCE







- When Monitored:
Continuously

- Set Condition:
When the Cluster senses a low or open condition on the (P33) Door Lock Driver circuit during a lock command for over 10 seconds, this code will set.





1. TEST FOR INTERMITTENT CONDITION
1. With the scan tool, record and erase DTC's
2. Operate the door locks several times.
3. Cycle the ignition from on to off.
4. Turn the ignition on.
5. With the scan tool, read DTC's.

Does the scan tool display B182C-ALL DOOR LOCK CONTROL CIRCUIT PERFORMANCE?

Yes

- Go To 2

No

- The conditions that caused this code to set are not present at this time. Using the wiring diagram/schematic as a guide, inspect the wiring and connectors.
- Perform the BODY VERIFICATION TEST.Body Verification Test

2. (P33) DOOR LOCK DRIVER CIRCUIT SHORT TO GROUND




1. Turn the ignition off.

Is the resistance below 1,000.0 ohms?

Yes

- Repair the (P33) Door Lock Driver circuit for a short to ground.
- Perform the BODY VERIFICATION TEST.Body Verification Test

No

- Go To 3

3. (P33) DOOR LOCK DRIVER CIRCUIT SHORTED TO BATTERY
