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. |
