8B-10 CRUISE CONTROL SYSTEM
Diagnosis
The cruise control unit uses the cruise main indicator light and diagnosis the failure, when the control unit detects
abnormality on the table below.

PART POSSIBLE CAUSE DETECTION PERIOD DTC
Actuator Motor system short circuit Energizing motor 1-1
Clutch system short circuit Energizing clutch 1-2
Clutch system open circuit Energizing clutch 1-2
Mechanical defect Cruise controlling 1-3

DTC : Diagnostic Trouble Code

DTC Display Condition
1. With the vehicle stationary and the ignition ON, activate the ‘Cruise Cancel’ switch three times within 2 seconds.
2. If there are no DTC’s stored in the Cruise control unit, the LED on the Cruise Main switch will blink rapidly (2Hz).
3. Any DTC’s stored in the Cruise control unit will be displayed by the CRUISE SET warning lamp in the meter
cluster.
4. Read the set DTC’s by referring to then charts on this page.

NOTE:

The DTC display mode will be aborted if either the vehicle speed rises above 10km/h or the RESUME switch is
operated.

The control module stores the DTC in a ‘volatile’ memory – that is the memory is only active while the ignition is
ON.
Turning the ignition to the OFF position will clesr any stored DTC’s.
