Toyota RAV4 (XA40) 2013-2018 Service Manual: Footwell light circuit
Description
The main body ecu receives information regarding the door lock position switch and ignition switch, and turns on each foot light.
Wiring diagram
Inspection procedure
- Perform active test by intelligent tester (main body ecu)
- Connect the intelligent tester (with can vim) to the dlc3.
- Turn the ignition switch to the on position and press the intelligent tester main switch on
- Select the items below in the active test and then check the relay operation.
Ok: light comes on.
- Inspect fuse (dome)
- Remove the dome fuse from the engine room no. 2 Relay block.
- Measure the resistance of the fuse.
Standard resistance:
below 1 
- Inspect foot light
- Remove the foot light.
- Connect the positive (+) lead from the battery to terminal 2 and the negative (-) lead to terminal 1, then check that the light comes on.
Ok: light comes on.
- Check wire harness (battery - main body ecu)
- Install the foot light.
- Disconnect the e15 main body ecu connector.
- Measure the voltage of the wire harness side connector.
Standard voltage 
Replace instrument panel junction block (main body ecu)

Symptom confirmation and diagnostic trouble code
Hint:
The diagnostic system in the rav4 has various
functions.
The first function is the diagnostic trouble code
(dtc) check. A dtc is a code stored in the ecu
memory whenever a malfunction in the signal circuits
to the ecu occurs. In a dtc check, a previous
malfunction's dtc can be ch ...
