Transcription

1 RKE CONTROL VEHICLE STILITY CONTROL SYSTEM C 95 DTC C1223/43 S Control System Malfunction DESCRIPTION This DTC is output when the VSC system detects a malfunction in the S system. When DTC C1223/43 is stored, there is no malfunction in the skid control ECU. DTC No. DTC Detecting Condition Trouble reas C1223/43 S control system abnormal S control system C INSPECTION PROCEDURE 1 CHECK DTC Clear the DTC (See page C-45). Check if the same DTC is recorded (See page C-45). REPIR CIRCUITS INDICTED Y OUTPUT DTCS

2 C 96 RKE CONTROL VEHICLE STILITY CONTROL SYSTEM DTC C1231/31 Steering ngle Sensor Circuit Malfunction DTC C1290/66 Steering ngle Sensor Zero Point Malfunction C DESCRIPTION The steering angle sensor signal is sent to the skid control ECU via the CN communication system. When there is a malfunction in the communication system, the DTC will be detected by the diagnosis function. DTC No. DTC Detecting Conditions Trouble reas C1231/31 C1290/66 When ECU IG1 terminal voltage 9.5 V or more, steering angle sensor malfunction signal received. Steering angle sensor zero point calibration position significantly differs from recorded value. Steering angle sensor Steering angle sensor circuit CN communication system Master cylinder solenoid (skid control ECU) Steering angle sensor WIRING DIGRM Ignition Switch Steering ngle Sensor Skid Control ECU ECU-IG IG CNH CNH ECU- T CNL CNL M1 ESS Short Pin LT attery C135281E01 INSPECTION PROCEDURE NOTICE: When replacing the master cylinder solenoid, perform zero point calibration (See page C-24). HINT: When U0073/94, U0123/62, U0124/95 or U0126/63 are output together with C1231/31, inspect and repair the trouble areas indicated by U0073/94, U0123/62, U0124/95 or U0126/63 first.

3 RKE CONTROL VEHICLE STILITY CONTROL SYSTEM C 97 When the speed sensor or the yaw rate sensor has trouble, DTCs relating to the steering angle sensor may be output even when the steering angle sensor is normal. When DTCs relating to the speed sensor (C0200/31, C0205/32, C0210/33, C0215/34, C1235/35, C1236/36, C1238/38, C1239/39) or yaw rate (deceleration) sensor (C1232/32, C1234/34, C1243/43, C1244/44, C1245/45, C1381/97) are output together with other DTCs relating to the steering angle sensor, inspect and repair the speed sensor and yaw rate (deceleration) sensor first, and then inspect and repair the steering angle sensor. 1 CHECK CN COMMUNICTION SYSTEM C Check for CN communication system DTCs (See page C-14). REPIR CN COMMUNICTION SYSTEM 2 CHECK MOMENTRY INTERRUPTION (STEERING NGLE SENSOR) DLC3 CN VIM Intelligent Tester H102157E03 (c) (d) Connect the intelligent tester to the DLC3. Turn the ignition switch on. Turn the tester on. Using a intelligent tester, check for any momentary interruption in the wire harness and connector corresponding to a DTC. Select the following menu items: DIGNOSIS / OD/ MOD / select vehicle / S/VSC / DT LIST. DT LIST: S/VSC Item Measurement Item / Range (Display) Normal Condition STEERING SEN Steering angle sensor open detection : OPN_DET or NORML OPN_DET: Momentary interruption NORML: Normal OK: There are no momentary interruptions. OK (When troubleshooting in accordance with DTC CHRT) OK (When troubleshooting in accordance with PROLEM SYMPTOMS TLE) NG C C PROCEED TO NEXT CIRCUIT INSPECTION SHOWN IN PROLEM SYMPTOMS TLE Go to step 4

REPLCE MSTER CYLINDER SOLENOID 4 CHECK TERMINL VOLTGE (STEERING NGLE SENSOR) Steering ngle Sensor (harness side connector): IG ESS (c) (d) Remove the steering wheel and the column lower cover. Disconnect the steering angle sensor connector. Turn the ignition switch on. Measure the voltage. Standard voltage Tester Connection Specified Condition E16-1 (IG) - E16-2 (ESS) 11 to 14 V E16-9 (T) - E16-2 (ESS) 11 to 14 V E NG REPIR OR REPLCE HRNESS OR CONNECTOR T C135282E01 OK 5 REPLCE STEERING NGLE SENSOR Replace the steering angle sensor (See page C-205). NEXT 6 RECONFIRM DTC Clear the DTCs (See page C-45). Check if the same DTCs are recorded (See page C- 45).
