CRUISE CONTROL SYSTEM T Inspection Procedure Self-diagnosis 1. Connect a 1.4W test light between terminals D and F, of the cruise control unit connector. Note There is no wire in terminal D of the connector. Push the test light through the connector and touch the cor- responding pin on the control unit. 2. Turn the ignition switch to ON. 3. Turn the cruise control on by pressing the MAlN switch. The MAlN indicator light will come on. 4. Press and hold the RESUMEIACCEL switch for more than 3 seconds. The test light will illuminate for 3 se- conds and go out for 2 seconds. 5. The on-board diagnosis system is activated and the test light will flash if there is a problem. Refer to the chart be- low to obtain the problem code number. Note The cruise control system will not operate in self-diag- nosis mode. 6. After retrieving the code(s), drive the vehicle at more than 16 kmlh (10 MPH) or press the MAlN switch to deactivate self-diagnosis. The MAlN indicator light will go off. 7. Follow the action corresponding to the problem code. Service Code Table If there are two or more problems in the system, the problem with the highest priority will be indicated.
