Circuit/System Verification
With a scan tool, access BCM, Power Mode data display list and compare all parameters listed with the corresponding ignition key position. The PMM Power Mode Parameters table below illustrates the correct state of these input parameters in correspondence to the ignition switch position. The circuits which the individual parameters are related to are in parentheses.
- If any parameters are incorrect in any key position, refer to the Circuit/System Testing or Component Testing.
