DESCRIPTION
If a malfunction in the speed sensor signal circuit yaw rate sensor circuit occurs, the 4WD control ECU will
output this DTC.
INSPECTION PROCEDURE
HINT:
Check the condition of each related circuit connector before troubleshooting (see page IN-37).
(a) Clear the DTC (see page TF-16).
(b) Turn the ignition switch OFF.
(c) Turn the ignition switch ON again and check that CAN
communication system DTC(s) is not output.
(d) Drive the vehicle, accelerate to a speed of 20 km/h (12
mph) or more, and check if the speed sensor DTC (brake
control system DTC) is output (see page BC-57).
Result
HINT:
When DTCs indicating a CAN communication system
malfunction are output, repair the CAN communication
system before repairing each corresponding sensor.
B
C
A
(a) Replace the 4WD control ECU with a normally
functioning or new one.
(b) Reconfirm DTC.
