Charge Status Indicator B Control Circuit High
Voltage on the charge status indicator b control circuit is above the expected window. Wiring faults of this kind typically come from chafing, water ingress at connector seals, or pin push-back — a wiggle test on the harness while the code is active often confirms the location.
Affected components
- Charge status indicator b
- Wiring harness
Common causes
- High likelihood: Wire shorted to B+
- Medium likelihood: Open lamp
- Low likelihood: Connector pins corroded - high contact resistance
