How To Proceed With Troubleshooting

CRUISE CONTROL: DYNAMIC RADAR CRUISE CONTROL SYSTEM: HOW TO PROCEED WITH TROUBLESHOOTING

HINT
* Use the following procedures to troubleshoot the dynamic radar cruise control system.
* *: Use the Techstream.

1. VEHICLE BROUGHT TO WORKSHOP

NEXT -- Continue to next step.

2. INSPECT BATTERY VOLTAGE

Standard voltage:

11 to 14 V

If the voltage is below 11 V, recharge or replace the battery before proceeding.

NEXT -- Continue to next step.

3. CHECK COMMUNICATION FUNCTION OF CAN COMMUNICATION SYSTEM*

(a) Use the Techstream to check if the CAN communication system is functioning normally.

Result





B -- Go to CAN COMMUNICATION SYSTEM Diagnosis System
A -- Continue to next step.

4. CHECK FOR DTC*

(a) Check for DTCs Dynamic Radar Cruise Control System.

(b) Clear the DTCs Dynamic Radar Cruise Control System.

(c) Recheck for DTCs. Based on the DTCs output in the first step, try to force output of the dynamic radar cruise control system DTCs by simulating the conditions indicated by the DTCs.

Result





B -- Go to DIAGNOSTIC TROUBLE CODE CHART Dynamic Radar Cruise Control System
A -- Continue to next step.

5. PROBLEM SYMPTOMS TABLE

(a) Refer to Problem Symptoms Table Dynamic Radar Cruise Control System.

Result





B -- Go to step 7
A -- Continue to next step.

6. OVERALL ANALYSIS AND TROUBLESHOOTING*

(a) Operation Check Operation Check

(b) Terminals of ECU Dynamic Radar Cruise Control System

(c) Data List / Active Test Dynamic Radar Cruise Control System

NEXT -- Continue to next step.

7. ADJUST, REPAIR OR REPLACE

NOTICE:
* When the driving support ECU or ECM is replaced with a new one, initialization must be performed Programming and Relearning.
* When the millimeter wave radar sensor assembly is replaced with a new one, adjustment of the radar sensor beam axis must be performed Adjustments.

NEXT -- Continue to next step.

8. CONFIRMATION TEST

NEXT -- END
