22 (SL4+) - 21 (SL4-)	5.0 to 5.6 Ω

Measure the resistance according to the value(s) in the table below.

Standard resistance

Check for short

Tester Connection	Specified Condition
22 (SL4+) - Body ground	10 kΩ or higher
21 (SL4-) - Body ground	10 kΩ or higher

OK → REPLACE TCM

NG: Go to next step

Measure the resistance according to the value(s) in the table below.

Standard resistance

Tester Connection	Specified Condition 20°C (68°F)
1 - 2	5.0 to 5.6 Ω

Connect a positive (+) lead through a 21 W bulb to terminal 2 and a negative (-) lead to terminal 1 of the solenoid valve connector, then check the movement of the valve.
OK
