Diagnosis System

PARK ASSIST / MONITORING: INTUITIVE PARKING ASSIST SYSTEM: DIAGNOSIS SYSTEM

1. DESCRIPTION

(a) When troubleshooting a vehicle with a diagnosis system, the only difference from the usual troubleshooting procedure is connecting the Techstream to the vehicle and reading various data output from the clearance warning ECU*1 or parking assist ECU*2.

The clearance warning ECU*1 or parking assist ECU*2 stores DTCs when the ECU detects a malfunction in the ECU itself or in its circuits.

To check the DTCs, connect the Techstream to the DLC3 on the vehicle. The Techstream makes it possible to clear the DTCs, activate the various actuators, and check the freeze frame data and Data List.

* *1: w/o Side Monitor System

* *2: w/ Side Monitor System

2. CHECK DLC3

(a) Check the DLC3 General Information.
