Smart Cruise Control Switch Repair Procedures

Inspection

[Resistance Measurement]

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 (k?)
   SET -	5 - 6	0,31 ~ 0,35
   VOICE +	5 - 6	0,52 ~ 0,58
   CCS	5 - 6	2,42 ~ 2,67
   CANCEL	5 - 6	0,17 ~ 0,19
   CRUISE	5 - 6	0,84 ~ 0,92

3. 3
   If not within specification, replace the switch.

[Voltage Measurement]

1. 1
   Connect the cruise control switch connector to the control switch.

   

2. 2
   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	Voltage (V)
   SET -	5 - 6	1,04 ~ 1,44
   VOICE +	5 - 6	1,55 ~ 1,99
   CCS	5 - 6	3,35 ~ 3,83
   CANCEL	5 - 6	0,61 ~ 0,91
   CRUISE	5 - 6	2,24 ~ 2,44

3. 3
   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.
4. 4
   If the resistance is normal but the measured voltage is not within 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 cover (A) after loosening the screw.

   

4. 4
   Disconnect the cruise control switch connector.
5. 5
   Remove the cruise control switch mounting screws (A).

   

6. 6
   Remove the cruise control switch (A).

   

   

Installation

1. Install in the reverse order of removal.
