- Unplug computer module connector. Check resistance between terminal No. 13 and ground. If resistance is 3-6 ohms, replace computer module. If resistance is greater than 6 ohms, unplug electro-hydraulic valve connector. Check resistance between terminal No. 3 and ground.
- If resistance is one ohm or more, repair open circuit. If resistance is less than one ohm, check resistance between terminals No. 2 and 3. If resistance is 3-6 ohms, repair open in wire between terminal No. 2 and computer module. If resistance is over 6 ohms, replace electro-hydraulic valve.
