Pinpoint Test Notes
PINPOINT TESTSCAUTION:
- Do not make jumper connections except as directed. Incorrect connections may damage the voltage regulator test terminals, fuses or fuse links.
- Do not allow any metal object to come in contact with the generator housing and internal diode cooling fins. A short circuit may result and burn out the diodes.
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 DTCs.
- All voltage measurements are referenced to the negative (-) battery post unless otherwise specified.
- When the battery has been disconnected and reconnected, some abnormal drive symptoms may occur while the PCM relearns its fuel trim. The vehicle may need to be driven to relearn the strategy.
