DTC C1361: M/C PRESSURE SNSR. STUCK/LOW GAIN, DTC C1362: M/C PRESSURE SNSR. LOW VOLTAGE,
DTC C1363: M/C PRESSURE SNSR. HIGH VOLTAGE CIRCUIT OPERATION The master cylinder pressure sensor is incorporated in the hydraulic unit. When the
brake pedal is depressed, the sensor detects the fluid pressure in the master cylinder,
and converts it to voltage signal. TCL/ASC DTC SET CONDITIONS This DTC is set if the master cylinder pressure sensor is defective. TROUBLESHOOTING HINTS (The most likely causes for these DTCs are to set are:)
The CAN bus line is defective. Malfunction of the hydraulic unit (integrated with TCL/ASC-ECU)
DIAGNOSIS Required Special Tools:
MB991958: Scan Tool (MUT-III Sub Assembly)
MB991824: Vehicle Communication Interface (V.C.I.) MB991827: MUT-III USB Cable CAUTION: If there is any problem in the CAN bus lines, an
incorrect diagnostic trouble code may be set. Prior to
this diagnosis, diagnose the CAN bus lines.
CAUTION: Whenever the ECU is replaced, ensure that the CAN
bus lines are normal.

CIRCUIT OPERATION
The G and yaw rate sensor is energized by the ignition switch (IG2) through
multi-purpose fuse 13 and the G and yaw rate sensor terminal 1. The G and
yaw rate sensor out
put si
gnal is sent to the TCL/AS
C-ECU via the

CAN bus line.
TCL/ASC DTC SET CONDITIONS These codes are set at the following cases: DTC C1366: LATERAL G-SENSOR (SEIZURE OR ABNORMAL OUTPUT SIGNAL)
Lateral acceleration value from the sensor is abnormal, or the value does not
fluctuate during driving.
DTC C1371: YAW RATE G-SENSOR (SEIZURE, ABNORMAL OUTPUT SIGNAL OR OSCILLATION)
Yaw rate value from the sensor is abnormal, or the value does not fluctuate
during driving.
DTC C1381: STRAIGHT G-SENSOR (SEIZURE OR ABNORMAL OUTPUT SIGNAL)
Longitudinal acceleration value from the sensor is abnormal, or the value does
not fluctuate during driving.
DTC C1385: YAW RATE SENSOR (ABNORMAL OUTPUT OR POOR PERFORMANCE)
The system receives a abnormal flag for at least one second. The system receives a poor performance flag for at least 2.5 seconds.
DTC C1386: STRAIGHT G-SENSOR (LONGITUDINAL OR LATERAL PERFORMANCE DETERIORATED)
The system receives a abnormal flag for at least one second.
DTC C1387: LATERAL G-SENSOR/G PERFORMANCE (LATERAL G-SENSOR OR G PERFORMANCE) <
LONGITUDINAL OR LATERAL PERFORMANCE DETERIORATED >
The system receives a abnormal flag for at least one second. The system receives a poor performance flag for at least 2.5 seconds.
DTC C1388: YAW RATE SENSOR ACTIVE CHECK (ACTIVE CHECK FAILURE)
The system receives a abnormal flag for at least one second. The system receives a poor performance flag for at least 2.5 seconds.

consecutively two times.
TROUBLESHOOTING HINTS (The most likely causes for these DTCs are to set are:)
Current trouble
Malfunction of the G and yaw late sensor Damaged wiring harness or connector Malfunction of the hydraulic unit (integrated with TCL/ASC-ECU)
Past trouble Carry out diagnosis with particular emphasis on connector(s) or wiring harness
between the TCL/ASC-ECU and the G and yaw late sensor. For diagnosis
procedures, refer to HOW TO TREAT PAST TROUBLE
