Inspection Procedure

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

HINT:

The shift solenoid valve SL1 turns ON/OFF normally when the shift lever is on D:

SHIFT SOLENOID VALVES POSITION REFERENCE

ECM gear shift command	1st	2nd	3rd	4th	5th
Shift solenoid valve SL1	OFF	OFF	OFF	OFF	ON

INSPECT TRANSMISSION WIRE (SHIFT SOLENOID VALVE SL1)

Disconnect the E1 wire connector.
Measure the resistance of the transmission wire.

Standard resistance

RESISTANCE SPECIFICATION

Tester Connection	Condition	Specified Condition
12(SL1+) - 4(SL1-)	20°C (68°F)	5.0 to 5.6 Ω
12(SL1+) - Body ground	20°C (68°F)	10 kΩ or higher
4 (SL1-) - Body ground	20°C (68°F)	10 kΩ or higher

NG: GO TO step 3

CHECK WIRE HARNESS (TRANSMISSION WIRE - ECM)

Disconnect the E6 ECM connector.
Measure the resistance of the wire harness side connector.

Standard resistance

RESISTANCE SPECIFICATION

Tester Connection	Condition	Specified Condition
E6-19(SL1+) - E6-18 (SL1-)	20°C (68°F)	5.0 to 5.6 Ω
E6-19(SL1+) - Body ground	20°C (68°F)	10 kΩ or higher
E6-18(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 to the terminal of the solenoid connector, and the negative (-) lead to the solenoid body.
OK: Solenoid makes operating noise.

NG: REPLACE SHIFT SOLENOID VALVE SL1
