CIRCUIT OPERATION
A toothed ABS rotor generates a voltage pulse as it moves across the pickup
field of each ABS sensor. The amount of voltage generated at each wheel is determined by the clearance
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.

The TCL/ASC-ECU gathers information regarding lateral and longitudinal
accelerations and yaw rate, through the CAN bus line from the G and yaw rate
sensor. TCL/ASC DTC SET CONDITIONS The TCL/ASC-ECU activates the G and yaw rate sensor via a CAN bus line in
order to diagnose the sensor whenever the ignition switch is turned on. If the G and
yaw rate sensor does not respond to this request, this DTC will be set. TROUBLESHOOTING HINTS (The most likely causes for these DTC are to set are:)
Current trouble
The CAN bus line is defective. Damaged connector(s) The G and yaw rate sensor is defective. The TCL/ASC-ECU is defective.
Past trouble Carry out diagnosis with particular emphasis on connector(s) or wiring harness
between the TCL/ASC-ECU and the G and yaw rate sensor. For diagnosis
procedures, refer to HOW TO COPE WITH INTERMITTENT MALFUNCTIONS
