What does fault code C0074 mean?
1 Answers
C0074 fault code applies to all automobile manufacturers, meaning requested driving torque. More relevant information is as follows: 1. This fault code is related to the torque management of the Traction Control System (TCS). If the system detects rear wheel slippage, the Electronic Brake Control Module (EBCM) will request the Powertrain Control Module (PCM) to reduce torque. There are two wires between the EBCM and PCM. One is responsible for sending the requested torque from the EBCM to the PCM, and the other sends the delivered torque from the PCM back to the EBCM. 2. After troubleshooting the vehicle, the fault code must be cleared. When clearing the code, it is essential to strictly follow the specific vehicle's prescribed fault code clearing method. Under no circumstances should the negative ground cable be disconnected to clear the fault code. Otherwise, it may cause the following two issues: First, it can lead to the loss of normal records in the control center computer of some vehicle models. Many car owners are aware that most vehicle central computers have a memory function. If the negative battery cable is disconnected, it will automatically clear the engine operation experience data stored in the Random Access Memory (RAM). Second, it may also result in the loss of certain functions, such as frequently losing the audio lock feature.
