PINPOINT TEST B : No Power in ACC - Vehicles with a Conventional Ignition Switch: Notes

Diagnostic Overview 

No Power in ACC - Vehicles with a Conventional Ignition Switch 

Refer to Power Distribution/BCM for schematic and connector information.

Normal Operation and Fault Conditions 

When in ACC mode, the BCM module provides ground for the coil (control) side of the RUN/ACC relay located in the BCM. The RUN/ACC relay receives voltage from BCM fuse 10 (10A). The RUN/ACC relay is serviced with the BCM.

The BCM also provides a ground circuit for the coil side of the accessory delay relay located in the BCM. The accessory delay relay can be serviced separately from the BCM.

Visual Inspection and Diagnostic Pre-checks 

Make sure BCM fuse 10 (10A) is OK.
