Engine Hood Switch Circuit Low
The hood switch input reads stuck low — short to ground or stuck-closed switch. The body controller may treat the hood as permanently open and refuse to arm the alarm or close the HV interlock.
Affected components
- Hood switch
Common causes
- High likelihood: Switch wire shorted to ground
- Low likelihood: Connector pins corroded - high contact resistance
- Low likelihood: Harness chafing through insulation
