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)

Solenoid circuit
Description
This solenoid is turned on in accordance with signals from the skid control
ecu and controls the pressure
on the wheel cylinders to control the braking force.
The solenoid and solenoid relay are built into the abs and traction actuator.
