Inspect headlight cleaner control relay operation.

Measure the resistance between terminals 4 (E) and 6 (PB).

Connect the positive (+) battery lead to terminal 3 (IG) of the connector, and the negative (-) battery lead to terminal 4 (E).

Connect the negative (-) battery lead to terminal 1 (HOLD) and 2 (H), and measure the resistance between terminals 4 (E) and 6 (PB).

  • Standard resistance:
  • Tester ConnectionConditionSpecified Condition
    4 (E) - 6 (PB)Always10 kΩor higher
    4 (E) - 6 (PB)When apply the battery voltageBelow 1 Ω
    4 (E) - 6 (PB)0.8 to 0.9 seconds after apply the battery voltage10 kΩ or higher

Disconnect the negative (-) battery lead from terminal 1 (HOLD) and 2 (H).

Disconnect the positive (+) battery lead from terminal 3 (IG), and then reconnect it.
