DIAGNOSIS SYSTEM
1. DESCRIPTION
(a) When troubleshooting a vehicle with a diagnosis system, connect the intelligent tester or Techstream to the DLC3 of the vehicle and read
various data output from the steering lock ECU.
The steering lock ECU records DTCs when the ECU detects a malfunction in itself or in its circuits.
(b) The diagnosis information of the steering lock ECU is transmitted to the tester via the certification ECU as the steering lock ECU is not
connected to the CAN communication system.
(c) The steering lock ECU does not store DTCs regarding past problems.
HINT: When the power switch is OFF, the main body ECU to which the intelligent tester or Techstream is to be connected may be
