CRUISE CONTROL SYSTEM Cruise SET Indicator Light Circuit

DESCRIPTION

The ECM illuminates the cruise control SET indicator by sending indicator output demand signals to the combination meter assembly via CAN communication. The cruise control SET indicator illuminates when the cruise control system is controlling vehicle speed. The cruise SET indicator light circuit uses CAN communication. If the cruise control SET indicator is not functioning correctly, check for CAN communication DTCs before troubleshooting this circuit.

CAUTION / NOTICE / HINT

CAUTION:

Observe the following items for safety reasons when using the GTS:


  • Before using the GTS, read the instruction manual.

  • B001D1J

    Prevent the GTS cable from being caught on the pedals, shift lever or steering wheel when driving with the GTS connected to the vehicle.

  • B001G32

    When driving the vehicle for testing purposes, 2 people are required. One person should operate the GTS while the other drives the vehicle.

Note


  • When replacing the combination meter assembly, always replace it with a new one. If a combination meter assembly which was installed to another vehicle is used, the information stored in it will not match the information from the vehicle and a DTC may be stored.

  • Before replacing the ECM refer to Service Bulletin.
