Diagnosis System
WARNING: This page is about a different car, the 2008 Lexus IS F. However, it is still accessible from the selected car via links, so may be relevant.
- DESCRIPTION
- When troubleshooting a vehicle with the diagnosis system, the only difference from the usual troubleshooting procedure is connecting the Techstream to the vehicle and reading various data output from the vehicle's clearance warning ECU. The clearance warning ECU records DTC s when the ECU detects a malfunction in the ECU itself or in its circuits.
To check the DTC s, connect the Techstream to the DLC3 on the vehicle. The Techstream enables you to clear the DTC s, activate the various actuators, and check the freeze frame data and Data List.
