Tip:

Battery voltage must be substantiated by a Midtronics M0R340V printout. Printout must be attached to the repair order. If ECM is requested by the
Warranty Test Center, a copy of the Midtronics Tester printout must be sent with the ECM along with all other supporting documentation.

-

With battery fully charged:

-

Connect the VAS 5051/5052 Diagnostic tool.

-

Switch ignition ON.

-

Select "Vehicle Self Diagnosis".

-

Interrogate and erase DTC memory.

-

Perform throttle adaptation (see appropriate Repair Manual and Repair Group 23 or 24).

-

Start engine and allow to run briefly, then switch engine OFF.

-

Repeat above step (Start/Shut OFF) 5 times.

-

Check DTC memory again.

If MIL does not illuminate and DTC has not returned:

^

A low battery condition most likely caused the DTC to be stored.

-

Set readiness code.

If MIL illuminates or DTC has been stored again, perform the following:

-

Replace ECM (see appropriate Repair Manual and Repair Group 23 or 24).

-

Set readiness code.

When procedure applies to vehicles within the New Vehicle Limited Warranty, use the table.
