^ Do not automatically replace the ECM for this condition. First, perform the following:
^ Verify that battery voltage and condition are OK (charge and load test as necessary).
If battery voltage is low:
^ Correct reason for low battery voltage
Tip:
Battery voltage must be substantiated by a Midtronics MCR340V printout. The printout must be attached to the repair order. If the 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:
^ Clear any stored DTC.
^ Perform throttle adaptation procedure (see Repair Group 24, ECM to throttle valve control module, adaptation.
^ Test drive vehicle for approximately one half hour.
If MIL does not illuminate and DTC does not return:
Low battery voltage has most likely caused the DTC to be stored.
^ Procedure is complete.
If MIL illuminates and DTC is stored again, perform the following:
