Fault (Trouble) Code 5/33429

1. With ECU connector disconnected, check resistance in circuit between pin 3 and pin 37 of TC/ABS-system ECU using breakout box. Resistance should be 6-8 ohms.
a. If circuit is good, clear fault code and test drive vehicle to see if fault code is regenerated. If so, try a known good ECU.
b. If circuit is faulty, go to step 2.
2. Check for continuity in TC-valve (NC) winding by measuring resistance across pins 4 and 5 on valve-block connector. Resistance should be 6-8 ohms.
3. Check lead between pin 4 on TC block and pin 37 on TC/ABS-system ECU for a broken or short circuit.
4. Check lead between pin 5 on TC block and pin 3 on TC/ABS-system ECU for a broken or short circuit.
