| Inspection |
| [Measuring Resistance] |
| 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. |
| [Measuring Voltage] |
| 1. |
Connect the cruise control switch connector to the control switch.
|
| 2. |
Measure voltage between terminals on the harness side 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, the measured voltage is not within
specification, inspect the wiring harness and connectors between the
switch and the ECM. |
| Installation |
| 1. |
Install in the reverse order of removal. |
Replacement 1. Discharge refrigerant from refrigeration system. 2. Replace any faulty tubes or hoses. Cap the open fittings immediately to keep moisture or dirt out of the system. 3. Tighten the bolt or nut joint to the specified torque.
Description This system maintains the density of carbon dioxide constantly in vehicle interior by measuring the amount of carbon dioxide to increase the comfortableness and the fuel consumption rate when air conditioning system is operating.
