Checking Input of Cruise Control Sub Switch

DIAGNOSIS:
- SET/COAST SW or disconnection of the wiring or short circuit.
- RESUME/ACCEL SW or disconnection of the wiring or short circuit.

TROUBLE SYMPTOM:
- Cruise control cannot be set, or it is cancelled immediately.
- RESUME/ACCEL cannot be operated.




1. CHECK THE SIGNAL USING A SELECT MONITOR
- Measuring condition: Turn ON the ignition switch and cruise main switch.
- Operation of the function keys: FAO ENT When pushing the SET SW: LED No.3 goes out - lights
When pushing the RESUME SW: LED No.4 goes out - lights

2. CHECK THE CRUISE SUB SWITCH




1. Separate connector from sub switch. (Use together with horn power supply.)
2. Check voltage between sub switch connector and body.

Terminals / Specified voltage:
No.1 - Body / 10 - 13 V

3. Check for harness short circuit between sub switch and cruise control module.

Terminals / Specified resistance:
No.2 - Body / 1 MOhm, min.
No.3 - Body / 1 MOhm, min.




4. Check inner switch of the cruise control sub switch and check continuity at switch side connector.

Terminals:
No.1 - 2 (SET/COAST SWITCH)
No.1 - 3 (RESUME/ACCEL SWITCH)

Specified resistance:
10 Ohm, max. (Switch ON)
1 MOhm, mm. (Switch OFF)
