Chart B1 Ignition Enable Circuit: Notes

Ignition enable circuit activates EBCM to perform self-check. When ignition is turned on, 12 volts are routed from ignition switch through EBCM 5-amp fuse, located under dash near steering column, to EBCM pin No. 2.

EBCM is grounded through pin No. 1 on circuit 450E to ABS ground junction, located inside engine compartment, on right fender side rail. Failure of this circuit will prevent EBCM from activating.
