This bulletin is in response to general inquires:
| • | About batteries and generators |
| • | Requirements for the Battery/Generator Diagnostic Work Sheet |
| • | From National Dealer Council meetings and the Fixed Operations Advisory Board |
This bulletin emphasizes two points:
| • | Completion of the Electrical System Diagnostic Work Sheet is intended to ensure that only faulty batteries and generators are replaced and to protect dealers from potential charge backs for generator or battery replacements where returned parts inspections reveal No Trouble Found (NTF). |
| • | To emphasize that we will pay for completion of the Electrical System Diagnostic Work Sheet in the following ways: |
| - | N0110, Battery R&R, will have the following added to the labor code: ADD -- To complete Electrical System Diagnostic Worksheet - 0.7 hr. |
| - | J4100, Generator R&R, will have the following added to the labor code: ADD -- To complete Electrical System Diagnostic Worksheet - 0.7 hr. |
| - | N9995, Customer concern not duplicated. This is a straight time labor operation code and should be used when the Electrical System Diagnostic Work Sheet is completed and no trouble is found with the electrical system of the vehicle. This labor code has the following note: "Actual time from 0.1 to 0.3 hours spent to perform the diagnosis is to be entered as "Labor Hours" for this operation. Any additional diagnosis time greater than 0.3 hours must be submitted as "Other Labor Hours", and have appropriate Service Management approval and authorization". |
