DIAGNOSIS SYSTEM

When troubleshooting is conducted for Multiplex OBD (M-OBD) vehicles, the only difference from the usual troubleshooting procedure is that the LEXUS hand-held tester is to be connected to read off various data output from the vehicle's skid control ECU.

The skid control ECU records the corresponding DTC when the computer detects a malfunction in the computer itself or its circuit.

To check DTC, connect a LEXUS hand-held tester to DLC3 on the vehicle. The LEXUS hand-held tester enables you to erase DTC and activate the several solenoids and actuators, and check freeze frame data and various forms on skid control data.
