P–92 ON-BOARD DIAGNOSTIC (DYNAMIC STABILITY CONTROL) DTC C1510, C1511, C1512, C1513 A6E697367650W21 Diagnostic procedure End Of Sie DTC C1953, C1954 A6E697367650W18 Diagnostic procedure End Of Sie DTC C1510 RF solenoid valve, motor or RF wheel-speed sensor/sensor rotor DETECTION CONDITION • Wheel lock is detected during ABS operation (pressure reduction inoperative). • Pressure reduction on a single wheel continues for 20 seconds or more. POSSIBLE CAUSE • Malfunction of solenoid valve in DSC HU/CM • Malfunction of wheel-speed sensor • Damaged sensor rotor • Stuck pump motor in DSC HU/CM STEP INSPECTION ACTION 1 VERIFY OTHER DTC HAS BEEN RECORDED • Has any wheel speed sensor, sensor rotor, solenoid valve, pump motor, or motor relay Yes Go to applicable DTC inspection. No Go to next step. 2 INSPECT DSC HU/CM OPERATION • Perform DSC HU/CM system inspection. • Is it okay? Yes Go to next step. No Replace DSC HU/CM, then go to next step. 3 VERIFY CURRENT STATUS OF • Clear DTC from memory. • Start engine and drive vehicle at 10 km/h {6.2 mph} or above at least one minute. • Gradually slow down and stop vehicle. • Is same DTC present? Yes Replace DSC HU/CM, then go to next step. No Go to next step. 4 VERIFY AFTER REPAIR PROCEDURE • Is there any other DTC present? Yes Go to applicable DTC inspection. No Troubleshooting completed. DTC C1953, C1954 Brake fluid pressure sensor DETECTION CONDITION • C1953: — Monitor voltage of the brake fluid pressure sensor is detected at 4.5 V or more, or 0.5 V or less. • C1954: — Brake fluid pressure sensor 0-point correction value is 0.3 V or less, or 0.9 V or more. exceeds specification. POSSIBLE CAUSE • Malfunction of brake fluid pressure sensor STEP INSPECTION ACTION 1 INSPECT BRAKE FLUID PRESSURE • Inspect PID/DATA in brake fluid pressure sensor. • Inspect MCYLIP item using WDS or equivalent. • Is pressure value change between 0—22.5 MPa when brake pedal is pressed? Yes Go to next step. No Repair DSC HU/CM. 2 VERIFY TROUBLESHOOTING COMPLETED • Clear DTC from memory. • Is same DTC present? Yes Replace DSC HU/CM, then go to next step. No Go to next step. 3 VERIFY AFTER REPAIR PROCEDURE • Is there any other DTC present? Yes Go to applicable DTC inspection. No Troubleshooting completed. |
