DIAGNOSIS SYSTEM
1. DESCRIPTION
a) DIAGNOSTIC SYSTEM
When troubleshooting a vehicle with a diagnostic system, the only difference from the usual troubleshooting procedure is connecting the
intelligent tester to the vehicle and reading various data output from the vehicle's steering lock ECU. The steering lock ECU records DTCs
when the computer detects a malfunction in the computer itself or in its circuits.
To check the DTCs, connect the intelligent tester to the DLC3 on the vehicle. The intelligent tester enables the DTCs to be cleared, the
indicators to be activated, and the DATA LIST to be checked.
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 BEAN.
