Toyota RAV4 (XA40) 2013-2018 Service Manual: Combination meter ecu communication stop mode
Description
Wiring diagram
Inspection procedure
Notice:
- Turn the ignition switch off before measuring the resistances of the main wire and the branch wire.
- After the ignition switch is turned off, check that the key reminder warning system and light reminder warning system are not in operation.
- Before measuring the resistance, leave the vehicle for at least 1 minute and do not operate the ignition switch, any switches or doors. If doors need to be opened in order to check connectors, open the doors and leave them open.
Hint:
Operating the ignition switch, any switches or any doors triggers related ecu and sensor communication with the can, which causes resistance variation.
- Check wire harness (combination meter ecu - battery and body ground)
- Disconnect the e19 combination meter ecu connector.
- Measure the resistance of the wire harness side connector.
Standard resistance
- Measure the voltage of the wire harness side connector.
Standard voltage
Replace combination meter ecu

Pressure control solenoid "b" electrical (shift solenoid valve sl2)
Description
Shifting from 1st to o/d is performed in combination with the on and off
operation of the shift solenoid
valves sl1 and sl2, which are controlled by the ecm. If an open or short circuit
occurs in any of the shift
solenoid valves, the ecm controls the remaining normal shift sol ...
Air outlet damper control servo motor circuit
Description
The damper servo sends pulse signals to indicate the damper position to the
air conditioning amplifier.
The air conditioning amplifier activates the motor (normal or reverse) based on
these signals to move the
mode damper to the appropriate position, which controls the air o ...
