Toyota RAV4 (XA40) 2013-2018 Service Manual: Shift solenoid "d" control circuit

Toyota RAV4. Shift solenoid "d" control circuit


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 solenoid valves to allow the vehicle to be operated safely (see page ax-31).

Monitor description

This dtc indicates an open or short in the shift solenoid valve s4 circuit. The ecm commands gear shifts by turning the shift solenoid valves on/off. When there is an open or short circuit in any shift solenoid valve circuit, the ecm detects the problem, illuminates the mil and stores the dtc. Also, the ecm performs the fail-safe function and turns the other normal shift solenoid valves on/off. In case of an open or short circuit, the ecm stops sending current to the circuit (see page ax-31).

  1. Disconnect the b27 wire connector.
  2. Measure the resistance of the transmission wire.

Standard resistance




  1. Check wire harness (transmission wire - ecm)

  1. Disconnect the b30 ecm connector.
  2. Measure the resistance of the wire harness side connector.

Standard resistance




Replace ecm

  1. Inspect shift solenoid valve s4

  1. Remove the shift solenoid valve s4.
  2. Measure the resistance of the solenoid valve.

Standard resistance: 11 to 15 at 20°c (68°f)


  1. Connect the battery's positive (+) lead to the terminal of the solenoid valve connector, and the negative (-) lead to the solenoid body. Then check that the valve moves and makes an operating noise.

Ok: valve moves and makes operating noise.
