ON-BOARD DIAGNOSTIC SYSTEM SIMULATION INSPECTION [EW6A-EL]

id050234290400

1.  Connect the M-MDS to the DLC-2.

2.  After the vehicle is identified, select the following items from the initialization screen of the M-MDS.

(1)  Select “Data Logger”.
(2)  Select “Modules”.
(3)  Select “TCM”.

3.  Select the simulation items from the PID table.

4.  Perform the active command modes function, inspect the operations for each parts.

•  If the operation of output parts cannot be verified after the active command mode inspection is performed, this could indicate the possibility of an open or short circuit, sticking, or operation malfunction in the output parts.
