Description
The circuit is used to send trc and vsc control information from the skid control ecu to the ecm, and engine control information from the ecm to the skid control ecu.
Inspection procedure
Hint:
Check that the part numbers of the installed ecm and skid control ecu are correct before performing the following procedure.
Result
Replace ecm
Zero point calibration
Description
The abs and traction actuator (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 and detects the vehicle's condition using 2 circuits (gl1, gl2). If there are problems in the bus lines between the yaw rate and deceleration sensor and the can communication system, dtcs u0123/62 (yaw rate sensor communication trouble) and u0124/95 (deceleration sensor communication trouble) are output.
The dtcs are also output when the calibration has not been completed.
Wiring diagram
Inspection procedure
Notice:
When replacing the abs and traction actuator, perform the zero point calibration (see page bc- 24).
Hint
When dtc u0123/62, u0124/95 or u0126/63 is output together with dtc c1210/36 or c1336/39, inspect and repair trouble areas indicated by dtc u0123/62, u0124/95 or u0126/63 first.
Ok: the sensor is tightened to the specified torque.
The sensor is not tilted.
Result
Hint:
Replace abs and traction actuator assembly

Unless otherwise stated, all resistance
measurements should be made at an ambient
temperature of 20°c (68°f). Resistance

Calibration
Description
After replacing components relating to the vsc or
performing "front wheel alignment adjustment",
clear and read the sensor calibration data.
Follow the chart to perform calibration.
