Pinpoint Test V: PHRCM POWER SUPPLY OR GROUND FAULT
- CHECK THE PERMANENT SUPPLY TO THE PHRCM
Disconnect the PHRCM electrical connector, SP22.
Measure the voltage between SP22, pin 01 (N) and GROUND.
Is the voltage less than 10 volts?
YES: REPAIR the circuit between the PHRCM and battery. This circuit includes the passenger side fuse box, (fuse 08) and the high power protection module. For additional information, refer to the wiring diagrams. Test the system for normal operation.
NO: Go to step 2.
- CHECK THE PERMANENT GROUND TO THE PHRCM
Measure the resistance between SP22, pin 06 (G) and GROUND.
Is the resistance greater than 5 ohms?
YES: REPAIR the high resistance circuit. For additional information, refer to the wiring diagrams. Test the system for normal operation.
NO: Check for DTCs indicating a faulty circuit. Contact dealer technical support for advice on possible DDCM failure
