Normal Operation
When the ignition is turned ON a relay inside the PSCM is energized, which sends power to other portions of the module. The PSCM monitors this relay output and sets a DTC if output is not detected.
This test generates a RVC for a new PSCM when directed to do so from pinpoint test. A RVC is required to order a new PSCM and to document billing for payment.
NOTE:
If a damaged bellows boot(s) was discovered during Inspection and Verification and this pinpoint test DOES NOT lead to the installation of a new EPAS gear or bellows boot(s), then go to PINPOINT TEST K to address the damaged boot(s) before returning the vehicle to the customer.
