Description
The main body ecu controls the daytime running light no. 2 Relay (marking:
drl no.2).
Wiring diagram
Inspection procedure
- Inspect daytime running light relay (marking: drl no. 2, Drl no. 3,
Drl no. 4)
- Remove the no. 2 Relay, no. 3 Relay and no. 4 Relay from
the engine room no. 2 Relay block.
- Measure the resistance of the relays.
Standard resistance:
No. 2, No. 4
No. 3
- Inspect fuse (head lh)
- Remove the head lh fuse from the engine room no. 2
Relay block.
- Measure the resistance of the fuse.
Standard resistance:
below 1
- Inspect headlight bulb (high)
- Remove the headlight bulb (high).
- Connect the positive (+) lead from the battery to terminal
2 and the negative (-) lead to terminal 1, then check that
the bulb illuminates.
- Check wire harness (battery - no. 2 Daytime running light relay)
- Remove the no. 2 Daytime running light relay from the
engine room no. 2 Relay block.
- Measure the voltage of the relay block.
Standard voltage
- Check wire harness (no. 2 Daytime running light relay - headlight
bulb and body ground)
- Remove the no. 2 Daytime running light relay from the
engine room no. 2 Relay block.
- Disconnect the a14 and a22 headlight (high)
connectors.
- Measure the resistance of the wire harness side
connectors and relay block.
Standard resistance
- Check wire harness (main body ecu - battery)
- Disconnect the e16 main body ecu connector.
- Measure the voltage of the wire harness side connector.
Standard voltage
Replace instrument panel junction block (main body ecu)
