STEERING LOCK SYSTEM > DIAGNOSIS SYSTEM

for Preparation Click here

1. When troubleshooting a vehicle with a diagnosis system, connect the intelligent tester to the DLC3 of the vehicle and read various data output from the steering lock ECU.
   The steering lock ECU records DTCs when the computer detects a malfunction in the computer itself or in its circuits.
   

2. The diagnosis information of the steering lock ECU is transmitted to the tester via the certification ECU because the steering lock ECU is not connected to the CAN communication system.
   

3. The steering lock ECU does not store DTCs regarding past problems.
   

   HINT:

   When the engine switch is off, the power management control ECU*1 or power source control ECU*2 may not be working.

   Communication with the intelligent tester is impossible if the power management control ECU*1 or power source control ECU*2 is not working.
