CHECKING RELAYS

Check each relay for continuity with the pocket tester. If the continuity reading is incorrect, replace the relay.
Pocket tester
    90890-03112

Analog pocket tester
    YU-03112-C
1. Disconnect the relay from the wire harness.
2. Connect the pocket tester (Ohms. x 1) and battery (+12VDC) to the relay terminal as shown.

    Check the relay operation.

    If out of specification -> Replace.
CHECKING THE RELAY UNIT (DIODE)

Relay unit (diode)

1. Check:
    • Relay unit (diode)

       If out of specification -> Replace.
