Smart Cruise Control Switch Repair Procedures

Inspection

1. 1
   Disconnect the cruise control switch connector from the control switch.

   

2. 2
   Measure the resistance between the terminals of the control switch when each function switch is in the ON position (switch pressed).

   Function Switch	Terminal	Resistance (±5%) [kΩ]
   CANCEL	2 - 7	0,18
   SET-	2 - 7	0,33
   RESUME+	2 - 7	0,55
   CRUISE	2 - 7	0,88
   CCS	2 - 7	2,54

3. 3
   If not within specification, replace the switch.
4. 4
   Connect the cruise control switch connector to the control switch.

   

5. 5
   Measure the voltage between the connector terminals on the harness side when each function switch is in the ON position (switch pressed).

   Function Switch	Terminal	Resistance (±5%) [kΩ]
   CANCEL	2 - 7	0,76 ± 0,15
   SET-	2 - 7	1,24 ± 0,20
   RESUME+	2 - 7	1,77 ± 0,22
   CRUISE	2 - 7	2,34 ± 0,10
   CCS	2 - 7	3,59 ± 0,24

6. 6
   If it does not meet the specification, check the resistance of the control switch. If the measured resistance does not meet the specification, replace the switch and measure the voltage again.
7. 7
   If the resistance is normal but the measured voltage does not meet the specification, inspect the wiring harness and connectors between the switch and the engine control module.

Removal

1. 1
   Turn the ignition switch OFF and disconnect the negative (-) battery cable.
2. 2
   Remove the airbag module from the steering wheel. (Refer to Restraint System - Driver Airbag Module (DAB) and Clock Spring)
3. 3
   Remove the steering wheel cover (A) after loosening the screws.

   

4. 4
   Disconnect the remote control switch connector on the steering wheel (A). [Left]

5. 5
   Remove the steering wheel remote control switch (A) after loosening the mounting screws.

   

Installation

1. Install in the reverse order of removal.
