RF solenoid valve, motor or RF wheel-speed sensor/sensor rotor
LF solenoid valve, motor or LF wheel-speed sensor/sensor rotor
RR solenoid valve, motor or RR wheel-speed sensor/sensor rotor
LR solenoid valve, motor or LR 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
related DTC been output?
Yes Go to applicable DTC inspection.
No Go to next step.
2 INSPECT DSC HU/CM OPERATION
• Perform DSC HU/CM system inspection.
See P35 DSC 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
MALFUNCTION
• Clear DTC from memory.
See P46 Clearing DTCs Procedures
• 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.
 Monitor voltage difference of 0.4 V or more within 1 cycle is detected 8 times in 1 second.
• C1954:
 Brake fluid pressure sensor 0-point correction value is 0.3 V or less, or 0.9 V or more.
 Output voltage value from brake fluid pressure sensor does not increase above 0.06 V.
 Difference between estimated brake pressure value and output value of brake fluid pressure sensor
exceeds specification.
POSSIBLE
CAUSE
• Malfunction of brake fluid pressure sensor
STEP INSPECTION ACTION
1 INSPECT BRAKE FLUID PRESSURE
SENSOR
• 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.
(See P46 Clearing DTCs Procedures)
• 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.
