With Pulse

The pulse wiper system can be diagnosed in one of two ways. The system can be diagnosed by testing the harness and the switch with a volt-ohmmeter, and the motor with a series of voltages and resistances for each mode, or by using the J 34660 Windshield Wiper Systems Tester. The special tool will duplicate all the test parameters necessary for diagnosing the operation of the windshield wiper motor.
