BRAKE CONTROL: VEHICLE STABILITY CONTROL SYSTEM: C1336/39: Zero Point Calibration of Acceleration Sensor Undone

DTC C1336/39 - Zero Point Calibration of Acceleration Sensor Undone

DESCRIPTION





WIRING DIAGRAM





INSPECTION PROCEDURE

PROCEDURE

1. CLEAR DECELERATION SENSOR ZERO POINT CALIBRATION DATA
(a) Clear the zero point calibration data Testing and Inspection.
NEXT -- Continue to next step.
2. CHECK FOR DTC
(a) Check that DTC C1336/39 is not output.
OK:
DTC C1336/39 is not output.
OK -- END
NG -- Continue to next step.
3. INSPECT YAW RATE AND ACCELERATION SENSOR (INCLUDING DECELERATION SENSOR)




(a) Remove the console box and deceleration sensor.
(b) Connect 3 dry cell batteries of 1.5 V in series.
(c) Connect terminal 8 (VYS) to the batteries' positive (+) terminal and terminal 5 (GYAW) to the batteries' negative (-) terminal.
NOTE:
Do not apply voltage of 6 V or more to terminals 8 (VYS) and 5 (GYAW).
(d) Measure the output voltage of the sensor when the sensor is tilted forward and rearward.
Standard voltage:





HINT:
- If the sensor is tilted too much, it may output the wrong value.
- If the voltage is out of the specification, replace the sensor with a new one.
- When replacing the sensor, do not place the sensor upside down.

NG -- REPLACE YAW RATE AND ACCELERATION SENSOR
OK -- Continue to next step.
4. CHECK WIRE HARNESS (SKID CONTROL ECU - YAW RATE SENSOR)




(a) Disconnect the S6 ECU connector.
(b) Disconnect the Y1 sensor connector.
(c) Measure the resistance of the wire harness side connectors.
Standard resistance:






NG -- REPAIR OR REPLACE HARNESS AND CONNECTOR
OK -- REPLACE SKID CONTROL ECU
