Diagnosis & Repair

Ensure ignition is off. Disconnect throttle valve motor driver harness connectors and ABS ECU harness connectors. Using ohmmeter, check continuity of THD, TRC+ and TRC- circuits. Repair as needed. If all circuits are okay, replace throttle valve motor driver or ABS ECU, or both.
