Cruise Main Indicator Light Circuit

CRUISE CONTROL: DYNAMIC RADAR CRUISE CONTROL SYSTEM: Cruise Main Indicator Light Circuit
- Cruise Main Indicator Light Circuit

DESCRIPTION

When the cruise control main switch is turned on, the cruise main indicator light and READY indicator light come on. This indicates the control condition (presence or absence of a vehicle in front, vehicle-to-vehicle distance, and set vehicle speed) and fail-safe state through the CAN communication system. The master warning light and cruise main indicator light come on and vehicle-to-vehicle distance information is displayed on the combination meter as the alarm buzzer sounds. Items such as "E1", "E2", and "E3" are displayed on the multi-information display on the combination meter when the ECM detects signals from each sensor and actuator and sends them to the combination meter via CAN.

HINT
If the vehicle in front in the same lane significantly decreases vehicle speed or another vehicle moves in front of your vehicle, adequate deceleration cannot be applied and the vehicle-to-vehicle distance will shorten. At this time, the system sounds the buzzer to warn the driver. Each indicator in the dynamic radar cruise control uses CAN for communication. Therefore, if there are any malfunctions in this circuit, check for DTCs in the CAN communication system before troubleshooting this circuit.

INSPECTION PROCEDURE

PROCEDURE

1. PERFORM ACTIVE TEST USING TECHSTREAM

(a) Connect the Techstream to the DLC3.

(b) Turn the ignition switch to ON.

(c) Turn the Techstream on.

(d) Enter the following menus: Body Electrical / Combination Meter / Active Test.

(e) Check the cruise indicator light by performing the Active Test.

Combination Meter





OK:

The indicator light blinks/turns off.

NG -- REPLACE COMBINATION METER ASSEMBLY Removal
OK -- Continue to next step.

2. READ VALUE USING TECHSTREAM

(a) Connect the Techstream to the DLC3.

(b) Turn the ignition switch to ON.

(c) Turn the Techstream on.

(d) Enter the following menus: Powertrain / Radar Cruise / Data List.

(e) Check the Data List for proper functioning of the cruise main indicator light.

Radar Cruise





OK:

When the cruise control main switch is operated, the display changes as shown above.

HINT
1 is OK, but 2 is NG -> DTC output or ECM failure

NG -- REPLACE ECM Removal

OK -- PROCEED TO NEXT SUSPECTED AREA SHOWN IN PROBLEM SYMPTOMS TABLE Dynamic Radar Cruise Control System
