Diagnosis System

STEERING COLUMN: POWER TILT AND POWER TELESCOPIC STEERING COLUMN SYSTEM: DIAGNOSIS SYSTEM

1. DESCRIPTION

(a) When troubleshooting a vehicle with the diagnostic 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 multiplex tilt and telescopic ECU.

The multiplex tilt and telescopic ECU records DTCs when the ECU detects a malfunction in itself or in its circuits.

To check the DTCs, connect the Techstream to the DLC3 on the vehicle. The Techstream enables you to clear the DTCs, activate several actuators, and check the freeze frame data and various forms of steering data.

2. CHECK DLC3

(a) Check the DLC3 General Information.
