What does fault code C0003 mean?
1 Answers
Fault code C0003 indicates an error in the Traction Control System (TCS) control channel B valve 1. After troubleshooting the vehicle issue, the fault code needs to be cleared. When clearing the code, it is essential to strictly follow the specific clearing method designated for the particular vehicle model. Do not directly disconnect the negative battery cable solely to clear the fault code. The function of the Traction Control System is to control torque output by delaying ignition timing, upshifting early, starting in second gear, and preventing torque converter lockup and brake slippage when it detects drive wheel slip. During vehicle propulsion, the ABS system cannot prevent wheel spin. Therefore, the Traction Control System was developed specifically to prevent drive wheel spin. Since this system operates by regulating the driving force of the drive wheels, it is also commonly referred to as the Traction Control System.
