Inspection Procedure

WARNING: This page is about a different car, the 2007 Toyota RAV4. However, it is still accessible from the selected car via links, so may be relevant.

INSPECT TRANSMISSION WIRE (SHIFT SOLENOID VALVE S4)

Disconnect the B27 wire connector.

Measure the resistance of the transmission wire.

Standard resistance

RESISTANCE REFERENCE

Tester Connection	Condition	Specified Condition
8 (S4) - Body ground	20°C (68°F)	11 to 15 Ω

NG: Go to step 3

CHECK WIRE HARNESS (TRANSMISSION WIRE - ECM)

Disconnect the B30 ECM connector.

Measure the resistance of the wire harness side connector.

Standard resistance

RESISTANCE REFERENCE

Tester Connection	Condition	Specified Condition
B30-78 (S4) - Body ground	20°C (68°F)	11 to 15 Ω

NG: REPAIR OR REPLACE HARNESS AND CONNECTOR

OK: REPLACE ECM

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 Ω at 20°C (68°F)
3. 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.
NG: REPLACE SHIFT SOLENOID VALVE S4
