DESCRIPTION. WIRING DIAGRAM. INSPECTION PROCEDURE. CHECK CAN COMMUNICATION LINE. CHECK DTC (CAN COMMUNICATION SYSTEM).

DTC C1257/57 Power Supply Drive Circuit Description The motor relay (semiconductor relay) is built into the master cylinder solenoid and drives the pump motor based on a signal from the skid control ECU.

DTC C1256/56 Accumulator Low Pressure Description The accumulator pressure sensor is connected to the skid control ECU in the master cylinder solenoid.

DTC C1254/54 Pressure Switch Circuit Description The accumulator pressure sensor is connected to the skid control ECU in the master cylinder solenoid.

DTC C1253/53 Pump Motor Relay Malfunction Description The motor relay (semiconductor relay) is built into the master cylinder solenoid and drives the pump motor based on a signal from the skid control ECU.

DTC C0210/33 Rear Speed Sensor RH Circuit DTC C0215/34 Rear Speed Sensor LH Circuit DTC C1238/38 Foreign Object is Attached on Tip of Rear Speed Sensor RH DTC C1239/39 Foreign Object is Attached on Tip of Rear Speed Sensor LH

DTC C1252/52 Brake Booster Pump Motor on Time Abnormally Long Description The motor relay (semiconductor relay) is built into the master cylinder solenoid and drives the pump motor based on a signal from the skid control ECU.

DTC C1251/51 Open in Pump Motor Circuit Description The motor relay (semiconductor relay) is built into the master cylinder solenoid and drives the pump motor based on a signal from the skid control ECU.

DTC C1249/49 Open in Stop Light Switch Circuit Description The stop light switch signal is input to the skid control ECU and the skid control ECU detects the status of brake operation. The skid control ECU has an open detection circuit. If an open in the stop light switch input line or GND side stop light circuit is detected when the stop light switch is off, this DTC is stored.

WIRING DIAGRAM. INSPECTION PROCEDURE. INSPECT REAR DIFFERENTIAL LOCK POSITION SWITCH (NO. 1 TRANSFER INDICATOR SWITCH). CHECK HARNESS AND CONNECTOR (DIFFERENTIAL LOCK SWITCH - SKID CONTROL ECU AND BODY GROUND). CHECK DTC.
