Toyota RAV4 (XA40) 2013-2018 Service Manual: Check and replace ecu
Notice:
- The connector should not be disconnected from the ecu. Perform the inspection from the backside of the connector on the wire harness side.
- When no measuring condition is specified, perform the inspection with the engine stopped and the ignition switch on.
- Check that the connectors are fully seated. Check for loose, corroded or broken wires.
- First, check the ecu ground circuit. If it is faulty,
repair it. If it is normal, the ecu could be faulty.
Temporarily replace the ecu with a normally functioning one and check if the problem symptoms occur. If the problem symptoms disappear, replace the original ecu.
- Measure the resistance between the ecu
ground terminal and body ground.
Standard resistance: Below 1 ù
- Disconnect the ecu connector. Check the ground terminal on the ecu side and wire harness side for bending, corrosion or foreign matter. Lastly, check the contact pressure of the female terminals.
Check for short circuit
If the wire harness is ground shorted (fig. 5), Locate
