TROUBLESHOOTING
Before starting troubleshooting, inspect each of the following sections, and if there is an abnormality, carry out a repair.
1. | Check that the actuator and pulley assembly are all normal.
2. | Check if the pulley assembly and the movement of cables are working smoothly.
3. | Check if there is no excessive play or tension in each cable.
TROUBLESHOOTING PROCEDURES First, select the applicable malfunction symptom from the "TROUBLE SYMPTOM CHARTS" shown on nest pages. Determine the condition of all function circuits.
1. | Make the following preliminary inspections.
A. | Check that the installation of the actuator, accelerator cable are correct, and that the cables and links are securely connected.
B. | Check that the accelerator pedal moves smootyly.
C. | Adjust the cable so there is not excessive tension or excessive play on the accelerator cable.
D. | Check that the actuator and unit assembly, cruise main, control switch and the connector of each cancel switch are connected securely.
2. | Check in the sequence indicated in the "TROUBLE SYMPTOM CHARTS".
3. | If a normal condition is indicated, replace the cruise control module.
