CRUISE CONTROL SYSTEM > General Description
CAUTION

- When performing service operation, refer to “Repair Contents” in “General Description”. REPAIR CONTENTS>Repair Contents

- Before disconnecting connectors of sensors or units, be sure to disconnect the ground terminal from the battery sensor. When replacing the audio and MFD parts provided with memory functions, record the memory contents before disconnecting the ground terminal from the battery sensor.

- Be careful of the following items. Failing to do so may cause the airbag system malfunction.

  - Yellow connectors and harnesses with yellow tapes around them are the connectors and harnesses for the airbag system. When using a tester on these circuits, follow the cautions of “AIRBAG SYSTEM”. AIRBAG SYSTEM>General Description>CAUTION

  - Be careful not to damage the airbag system wiring harness when servicing the electrical parts around the steering column.

- When removing, installing or replacing the VDCCM&H/U, VDCCM&H/U bracket, steering wheel or steering angle sensor (steering roll connector), perform “VSC(VDC) Centering Mode” of the VDC.

CRUISE CONTROL SYSTEM > Cruise Control Command Switch
INSPECTION
1.

Measure the resistance between connector terminals.

Preparation tool:

Circuit tester

Terminal No. | Inspection conditions | Standard
3 — 9 | CANCEL SET/− RES/+ | All OFF | Approx. 4,020 Ω
CANCEL | ON | Less than 1 Ω
SET/− | ON | Approx. 250 Ω
RES/+ | ON | Approx. 1,470 Ω
4 — 9 | CRUISE | OFF | 3 MΩ or more
ON | Less than 1 Ω

2.

Apply battery voltage between the connector terminals to check lighting condition of illumination inside the switch.

When applying battery voltage, do not mix up the positive (+) side and the negative (−) side.

Incorrect polarity connection may cause LED damage inside the switch.

Terminal No. | Inspection conditions | Specification
10 (+) — 11 (−) | Apply battery voltage. | Light ON

3.

Replace the cruise control command switch if it is found defective.
