Lancer front ecu diagnostics code#
ASC-ECU uses the frequency of the pulse signals to determine the wheel speed.ĭIAGNOSIS CODE SET CONDITIONS ASC-ECU monitors the signals from each wheel speed sensor while the vehicle is being driven.
The pulse signals, which the wheel speed sensorĬreates, are sent to ASC-ECU. This sensor outputs frequency pulse signals in proportion to the wheel speed. It consists of encoders (a plate on which north and south pole sides of the magnets are arranged alternately) for detecting the wheel speed which rotates at the same speed of the wheels and wheel speed sensors. The wheel speed sensor is a kind of a pulse gen-Įrator. When the hydraulic unit (integrated with ASC-ĮCU) is replaced, always carry out the calibra- tion of the steering wheel sensor, the G and yaw rate sensor and brake fluid pressure sen- sor (Refer to. Whenever ECU is replaced, ensure that the. 
Prior to this diagnosis, diagnose the CAN bus lines (Refer to GROUP 54C
If there is any problem in the CAN bus lines,Īn incorrect diagnosis code may be set. (2) Drive the vehicle at 20 km/h or higher. Check whether the diagnosis code is reset. Replace the hydraulic unit (integrated with NOTE: The ABS warning lamp does not turn OFF in some cases unless the vehicle runs at 20 km/h or higher. Check whether the diagnosis code is reset. Intermittent malfunction (Refer to GROUP 00 NOTE: The ABS warning lamp does not turn OFF in some cases unless the vehicle runs at 20 km/h or higher. (2) Drive the vehicle at 20 km/h or higher. Check whether the diagnosis code is reset. Check of wheel speed detection encoderĬheck the encoder for adhesion of foreign materials or deformation.įoreign materials and clean the encoder so as not to disturb the magnetization pattern on it while taking care of the magnet, magnetic substance, and magnetic attraction. Replace the wheel bearing (Refer to GROUP 26 STEP 8. Check for wheel bearing looseness NOTE: Loose wheel bearing may increase the gap between the wheel speed sensor and the wheel speed detection magnet encoder. Replace the wheel speed sensor (Refer to STEP 7. Check for wheel speed sensor output current Re fer to Reinstall the wheel speed sensor correctly (Refer to STEP 6. Check for wheel speed sensor installation Check how the wheel speed sensor is installed (Disconnection of wheel speed sensor , loose mounting bolt, etc.). Repair the wiring harness. Then go to Step 12. STEP 5. Wiring harness check between A-58 ASC-ECU connector terminal No.34 and A-03 front wheel speed sensor connector terminal No.1 and between A-58 ASC-ECU connector terminal No.33 and A-03 front wheel speed sensor connector terminal No.2. Repair the defective connector. Then go to Step 12. STEP 4. Connector check: A-58 ASC-ECU connector, A-03 front wheel speed sensor connector STEP 3. M.U.T.-III diagnosis code Check that diagnosis code No. STEP 2. Diagnosis code recheck after resetting CAN bus lines Repair the CAN bus lines (Refer to GROUP 54C STEP 1. M.U.T.-III CAN bus diagnosis Use M.U.T.-III to diagnose the CAN bus lines. Vehicle ran with the parking brake applied. When diagnosis code No.C1015 is not set, the. 
Out diagnosis with particular emphasis on wiring harness and connector failures between ASC- ECU and the wheel speed sensor. For diagnosis procedures, refer to How to treat past trouble (GROUP 00 When diagnosis code No.C1015 is also set, carry.Wheel speed detection (N-pole and S-pole) is changed The number of poles on the Magnetic encoder for.Disturbance of magnetisation pattern for wheel.
