Pinpoint Test Notes

PINPOINT TESTS

CAUTION:
- Do not make jumper connections except as directed. Incorrect connections may damage the voltage regulator test terminals.
- 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, make sure to clear all codes in the PCM.
- The dual generator I circuit/bulb circuit 4-way connector MUST be connected before disconnecting or connecting the battery. The PCM relearns its parameters every time it is disconnected and connected to power. Failure to follow this procedure causes the PCM to misinterpret the charging system as a single generator system, causing loss of DTC capability and control.
- All voltage measurements are referenced to the negative (-) battery post unless otherwise specified.
