Zero Point Calibration of Deceleration Sensor Undone

DTC 39 ZERO POINT CALIBRATION OF DECLARATION SENSOR UNDONE

CIRCUIT DESCRIPTION

DTC Detection Condition:




The skid control ECU receives signals from the yaw rate and deceleration sensor via the CAN communication system.

The yaw rate sensor has a built-in deceleration sensor.

If there is trouble in the bus lines between the yaw rate and deceleration sensor and the CAN communication system, the DTC U0123/62 (yaw rate sensor communication trouble) and U0124/95 (deceleration sensor communication trouble) are output.

These DTCs are also output when the calibration has not been completed.

HINT:
If these codes (C1210/36 and/or C1336/39) are output, the following situations will occur:
- The VSC TRAC warning light and the VSC OFF and slip indicator lights will come on.
- Control of all systems other than ABS, EBD, and BA is canceled.

INSPECTION PROCEDURE

NOTE: When replacing the master cylinder solenoid, perform zero point calibration. Calibration

HINT: When U0073/94, U0100/65, U0123/62, U0124/95 or U0126/63 is output together with C1210/36 or C1336/39, inspect and repair the trouble areas indicated by U0073/94, U0100/65, U0123/62, U0124/95 or U0126/63 first.
