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
Front seat concentrated
airflow mode (S-FLOW)
This function automatically controls
the air conditioning airflow
so that priority is given to the
front seats. Unnecessary air
conditioning is suppressed, contributing
to increased fuel efficiency.
Front seat concentrated airflow
mode operates in the following
situations.
No passengers are detec ...
Ambient temperature sensor circuit
Description
The ambient temperature sensor is installed in the front part of the
condenser to detect the ambient
temperature and control the air conditioner. The sensor is connected to the
combination meter and
detects fluctuations in the ambient temperature. This data is used for
contr ...
