-> Yes GO to Pinpoint Test G215852t9.
-> No CHECK the circuit between the ECM and the generator for open circuit/high resistance. REPAIR as necessary. CLEAR the DTC, test the system for normal operation. If the fault persists, contact dealer technical support for advice on possible ECM failure. G215852t9 : CHECK THE "L" LINE FOR SHORT TO BATTERY 1. Turn the ignition switch to the OFF position. For vehicles with V6 engine •
Measure the voltage between PI47, pin 04 (YR) and GROUND. For vehicles with V8 engine •
Measure the voltage between PI47, pin 01 (YR) and GROUND. •
Is the voltage less than 1 volt? -> Yes GO to Pinpoint Test G215852t21.
-> No REPAIR the short circuit. For additional information, refer to the wiring diagrams. CLEAR the DTC, test the system for normal operation. G215852t21 : CHECK THE GENERATOR DRIVE PULLEY 1. Remove the accessory drive belt, <<303-05>> 2. Rotate the generator pulley by hand. •
Does the generator rotor shaft rotate with the pulley? -> Yes INSTALL a new generator. CLEAR the DTC, test the system for normal operation. If the fault is repeated, contact dealer technical support for advice on possible ECM failure.
-> No INSTALL a new generator. CLEAR the DTC, test the system for normal operation. G215852t7 : CHECK THE VOLTAGE AT THE GENERATOR SENSE TERMINAL 1. Disconnect the generator electrical connector, PI48. 2. Measure the voltage between PI48, pin 03 (NG) and GROUND. •
