Is the voltage less than 10 volts? -> Yes REPAIR the circuit between the RMM and battery. This circuit includes the primary junction box (fuse 28) and the SSP relay. For additional information, refer to the wiring diagrams. TEST the system for normal operation.
-> No CHECK for DTCs indicating a network or module fault. REFER to the DTC index. PINPOINT TEST G239843p19 : CHECK G239843t87 : CHECK THE PERMANENT SUPPLY TO THE ECM 1. Disconnect the ECM electrical connector, PI01. 2. Measure the voltage between PI01, pin 22 (NR) and GROUND. •
Is either voltage less than 10 volts? -> Yes REPAIR the circuit between the ECM and battery. This circuit includes the front power distribution box (fuse 17). For additional information, refer to the wiring diagrams. TEST the system for normal operation.
-> No GO to Pinpoint Test G239843t88.
G239843t88 : CHECK THE EMS SUPPLY TO THE ECM 1. Turn the ignition switch to the ON position. 2. Make sure the EMS relay is energized. 3. Measure the voltage between PI01, pins 23 and 24 (WG) and GROUND. •
Is the voltage less than 10 volts? -> Yes REPAIR the circuit between the ECM and battery. This circuit includes the front power distribution box (fuse 12) and the EMS relay. For additional information, refer to the wiring diagrams. TEST the system for normal operation.
-> No GO to Pinpoint Test G239843t89.
