Repair Procedures

Inspection

Check that the automatic light control operates as shown in the timing chart below. The tail lamp and headlamp (Low) are controlled based on the auto light sensor input (illumination intensity) when the auto light switch on the multifunction switch is ON and the vehicle is in IGN1 or IGN2 ON mode. If IGN1 is ON, the IBU determines this voltage, and if the voltage is outside the nominal range, an auto light malfunction occurs (below 4 V or above 6 V).

Removal

  1. Disconnect the negative (-) battery terminal.

  2. Remove the auto light sensor (A) from the main cushion.

  3. Disconnect the connector (A) from the auto light sensor.

Installation

  1. Install in the reverse order of removal.
