Pinpoint Tests: Notes

CAUTION: Do not make jumper connections except as directed. Incorrect connections may damage the voltage regulator test terminals, fuses or fuse links.

CAUTION: Do not allow any metal object to come in contact with the generator housing and internal diode cooling fins.

NOTE: While carrying out any pinpoint test, disregard any DTCs set while following any specific pinpoint test. After the completion of any test, be sure to clear all codes in the PCM.

NOTE: All voltage measurements are referenced to the negative (-) battery post unless otherwise specified.

NOTE: When the battery has been disconnected and reconnected, some abnormal drive symptoms may occur while the powertrain control module (PCM) relearns its fuel trim. The vehicle may need to be driven to relearn the strategy.
