Inspection Procedure

WARNING: This page is about a different car, the 2008 Toyota RAV4. However, it is still accessible from the selected car via links, so may be relevant.

INSPECT TRANSMISSION WIRE (SHIFT SOLENOID VALVE SL1)

Disconnect the B27 wire connector.

Measure the resistance of the transmission wire.

Standard resistance

TERMINALS RESISTANCE REFERENCE

Tester Connection	Condition	Specified Condition
5 (SL1+) - 10 (SL1-)	20°C (68°F)	5.0 to 5.6 Ω
5 (SL1+) - Body ground	20°C (68°F)	10 kΩ or higher
10 (SL1-) - Body ground	20°C (68°F)	10 kΩ or higher

NG: Go to step 3

OK: go to next step

CHECK WIRE HARNESS (TRANSMISSION WIRE - ECM)

Disconnect the B30 ECM connector.

Fig 2: Identifying Terminals Of B30 ECM Connector

Measure the resistance of the wire harness side connector.

Standard resistance

TERMINALS RESISTANCE REFERENCE

Tester Connection	Condition	Specified Condition
B30-57 (SL1+) - B30-77 (SL1-)	20°C (68°F)	5.0 to 5.6 Ω
B30-57 (SL1+) - Body ground	20°C (68°F)	10 kΩ or higher
B30-77 (SL1-) - Body ground	20°C (68°F)	10 kΩ or higher

NG: REPAIR OR REPLACE HARNESS AND CONNECTOR

OK: REPLACE ECM

INSPECT SHIFT SOLENOID VALVE SL1
1. Remove the shift solenoid valve SL1.
2. Measure the resistance of the solenoid valve.
  Standard resistance:
  
  5.0 to 5.6 Ω at 20°C (68°F)
3. Connect the battery's positive (+) lead with a 21 W bulb to terminal 2 and the negative (-) lead to terminal 1 of the solenoid valve connector. Then check that the valve moves and makes an operating noise.
  OK:
  
  Valve moves and makes operating noise.
NG: REPLACE SHIFT SOLENOID VALVE SL1

OK: REPAIR OR REPLACE TRANSMISSION WIRE
