Circuit/System Testing
NOTE:
Refer to DTC B3794 before performing this diagnostic, if this code is set as current or history.
- Ignition OFF, disconnect the harness connector at the steering wheel control switch-left.
- Ignition ON, verify that a test lamp illuminates between the low reference circuit terminal 9 and B+.
- If the test lamp does not illuminate, test the low reference circuit for a short to voltage or an open/high resistance. If the circuit tests normal, replace the BCM.
- If all circuits test normal, test or replace the steering wheel controls switch-left
