Diagnostic Test
1. INTERMITTENT CONDITIONTurn the ignition on.
With the scan tool, clear all DTC's.
Turn the High Beam Lamps on.
With the scan tool, read DTC's.
Does the scan tool display active: B1637-RIGHT HIGH BEAM CONTROL CIRCUIT LOW?
Yes
- Go To 2
No
- The condition that caused this symptom is currently not present. Check for an intermittent condition by inspecting the related wiring harness for chafed, pierced, pinched, and partially broken wires. Also, inspect the related connectors for broken, bent, pushed out, spread, corroded, or contaminated terminals. Repair as necessary.
