ACTION:
Use the following Service Procedure to determine if the EEC-V PCM requires replacement or reprogramming with a revised calibration.
SERVICE PROCEDURE
1.
Perform the EEC-V Self Test. If any of the listed codes appear, reprogram the PCM by following the SBDS instructions. Use SBDS
reprogramming tool, June 94" CD-ROM or later. If SBDS is not available, replace the PCM with a new service PCM. Refer to the PCM
Application Chart.
2.
Test drive the vehicle and perform the EEC-V Self Test. Confirm that there are no DTC codes. If any codes appear, refer to the 1995 Powertrain
Control/Emissions Diagnosis (OBD-II) Service Manual. Service as required.
