System Testing (With Traction Control)

Ensure related fuses are good. Use V.A.G. 1551 to retrieve any stored codes. Check for disconnected or damaged wires at sensors, grounds and battery feed circuits. Turn ignition off. Disconnect ABS ECU harness connector. Install Breakout Box V.A.G. 1598. Measure voltage (with ignition on) or resistance (with ignition off) as indicated in test charts. If necessary, use appropriate wiring diagram to isolate circuit related problems.
