DTC INSPECTION [EPS CONTROL MODULE]
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.a. Select “Self Test”.b. Select “All CMDTCs”.
3. Verify the DTC according to the directions on the screen.
If any DTCs are displayed, perform troubleshooting according to the corresponding DTC inspection. (See DTC TABLE [EPS CONTROL MODULE].)
NOTE:
Snapshot data appears at the top of the help screen when the displayed DTC is selected.
Snapshot data stores the currently detected DTC data.
4. After completion of repairs, clear all DTCs stored in the module. (See CLEARING DTC [EPS CONTROL MODULE].)
Snapshot Data Table
NOTE:
—: Not applicable
Refer to PID monitor table for confirm the EPS system operation status while the EPS control module does not store the DTC. (See PID/DATA MONITOR TABLE [EPS CONTROL MODULE].)
