TEST ACTION APPLICABILITY
1 Remove Circuit Breaker 2 from the Fuse Block.
Measure voltage of the Fused B+ circuit at the Circuit Breaker connector.
Is the voltage above 10.0 volts?
All
Yes → Go To 2
No → Repair the open Fused B+ circuit from Fuse Block fuse 15.
Perform BODY VERIFICATION TEST - VER 1.

All
Yes → Repair the Dimmer Switch Low Beam Output Circuit for a short
to ground condition.
Perform BODY VERIFICATION TEST - VER 1.
No → Go To 4
4 Remove Circuit Breaker 2 from the Fuse Block.
Disconnect the Multifunction Switch connector.
