DTC INSPECTION [INSTRUMENT CLUSTER]

CMDTC Self Test

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 after recording the snapshot data. (See DTC TABLE [INSTRUMENT CLUSTER].)

4. After completion of repairs, clear all DTCs stored in the instrument cluster. (See CLEARING DTC [INSTRUMENT CLUSTER].)

Key Out/Key Recently Out (Position 0)/Accessory (Position 1)/Post Ignition (Position 2)/Ignition On (Position 2)/Running (Position 2)/Running - Starting

  • Key Out: Ignition switched off

  • Key Recently Out (Position 0): Elapsed time within 3 s since ignition was switched off

  • Accessory (Position 1): Ignition is switched to ACC

  • Post Ignition (Position 2): Elapsed time within 3 s since ignition was switched ON (engine off or on)

  • Ignition On (Position 2): Ignition switched ON (engine off)

  • Running (Position 2): Ignition switched ON (engine on)

TOTAL_DIST

km

Miles

Accumulated total traveled distance from completion of vehicle until instrument cluster detects DTC (Odometer value in instrument cluster)

The total traveled distance from which the instrument cluster detects DTCs to the present can be calculated by performing the following procedure.

  • Verify the odometer value in the instrument cluster.

  • Verify the snapshot data item TOTAL_DIST.

  • Subtract 2 from 1.

—

TOTAL_TIME

hh:mm:ss*1

Accumulated total elapsed time since vehicle completion until instrument cluster detects a DTC

NOTE:

  • When the ROOM fuse is removed, and the ignition is switched off, the time is not included in the elapsed time.

The elapsed time from which the instrument cluster detects DTCs to the present can be calculated by performing the following procedure.

  • Verify the instrument cluster PID item TOTAL_TIME.

  • Verify the snapshot data item TOTAL_TIME.

  • Subtract 2 from 1.
