|
| 7. |
Installation is the reverse of removal. |
| Inspection |
| 1. |
Disconnect the cruise control switch connector from the control switch.
|
| 2. |
Measure resistance between terminals on the control switch when each function switch is ON (switch is depressed).
|
| 3. |
If not within specification, replace switch. |
| 1. |
Connect the cruise control switch connector to the control switch.
|
| 2. |
With ignition switch ON, measure voltage between terminals on
the harnessside connector when each function switch is ON (switch is
depressed).
|
| 3. |
If not within specification, inspect the control switch
resistance. The measuring resistance value is not within specification,
replace the switch and measure the voltage again. |
| 4. |
If resistance is OK but, measuring voltage is not within
specification, inspect the wiring harness and connectors between the
switch and the instrument cluster . |
