HEADLIGHT CLEANER (CANADA Only) Part Inspection 1. INSPECT HEADLIGHT CLEANER SWITCH Inspect switch continuity between terminals. Terminal Switch Position | 1 | 2 OFF | - | - ON | O | O If continuity is not as specified, replace the switch. 2. INSPECT HEADLIGHT CLEANER CONTROL RELAY (a) Check that there is no continuity between terminals 4 and 5. (b) Connect the positive (+) lead from the battery to terminal 3 and the negative (-) leads to terminals 1 and 5. (c) Check that there is continuity between terminals 4 and 5 for 0.4 to 0.6 seconds, then there is no continuity. 3. INSPECT RELAY CIRCUIT (a) Disconnect the control relay and inspect the connector on the wire harness side as shown in the chart below. Terminal | Check Item | Tester Connection | Condition | Voltage or Continuity 1 | Continuity | 1 - Body Ground | Turn light control switch to HEAD and turn headlight cleaner switch on | Continuity 1 | | | Turn light control switch to OFF or turn headlight cleaner switch off | No continuity 3 | Voltage | 3 - Body Ground | Turn ignition switch to ON | Battery voltage 3 | | | Turn ignition switch to LOCK or ACC | No voltage 5 | Continuity | 5 - Body Ground | - | Continuity (b) With the terminal 4 of the connector side grounded, check that the cleaner motor operates. NOTICE: These tests must be performed quickly (within 3 - 5 seconds) to prevent the coil from burning out. If circuit is as specified, replace the relay.
