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 assembly.

The clearance warning ECU assembly 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.

2. CHECK DLC3

(a) Check the DLC3 (See page Dtc Check / Clear ).
