DTC Readout (CF - Convenience Feature)
Applies to W140, 1992-93 model yearsé©ç”¨æ–¼W 140,1992-93典型年度

Testing with impulse counter scan tool:

1. Connect impulse counter scan tool according to connection diagram.

013 Impulse counter scan tool
075 Impulse counter scan tool adapter
X11/4 Data link connector (DTC readout, 38-pin)

Note: LED "U-Batt" must light up, if not, refer to detailed tests located in Specific Literature Recommendation listed below.

2. Ignition: ON

3. Press start button for 2 to 4 seconds.

4. Read and note DTC readout displayed. Display "1" = no fault stored, Greater than "1" = faults in system.

5. Press start button again for 2 to 4 seconds. If there are no further faults in the system, the previously displayed DTC will reappear. If additional faults exist, then the respective DTC will be displayed.

6. Repeat step 5 until the first DTC displayed is repeated.

7. Note any additional faults from the DTC readout.

8. Eliminate all noted faults (DTC readout) according to troubleshooting chart and diagnostic tests.

Erasing DTC memory:
After eliminating a fault, the respective DTC readout must be cleared as follows:

9. Press start button for 2 to 4 seconds and read out the DTC. Then press the start button for 6 to 8 seconds.
Note: Each DTC displayed must be erased individually.

10. Ignition: OFF and wait 30 seconds.

If the fault has been eliminated and its respective DTC erased, then the DTC will no longer be displayed when performing the DTC readout. If the DTC displayed is greater than 1, then there are further DTC's in the system.
