In order to allow equitable parts availability to all participating dealers, please limit your initial parts order to not exceed 1% of dealership population. This is an initial order recommendation only, and the ultimate responsibility for ordering the total number of parts needed to satisfy the program lies with the dealer.
|
Replace the 351-6078 A/C Control ECM (Module Assembly) with a new 351-6078 A/C Control ECM (Module Assembly). The new ECM will state "Rev A" on the back tag indicating that the software has been updated. All parts inventory has been updated so only an updated ECM can be purchased. |
