Toyota RAV4 (XA40) 2013-2018 Service Manual: Drl relay circuit
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)
