Headlight Beam Level Control System: Inspection: Notes

Inspect Headlight Beam Level Control Actuator Resistance
1. Check that continuity exists between terminal No. 2 and No. 5.
2. Check that resistance exists between terminal, as shown in the chart.
If resistance value is not as specified, replace the actuator.
Connector Disconnected: Inspect Headlight Beam Level Control ECU Circuit.
Disconnect the connector from the ECU and inspect the connector on the wire harness side, as shown. See Fig 3 and Fig 4.
