Introduction
The problem that is identified below does not have a known permanent solution. Until a permanent solution is known, use the solution that is identified below.
Problem
The 337-2 code is generated when engine Electronic Control Module (ECM) is powering up and the E-stop button is in inactive (closed) state. This problem affects certain C32 and 3500 generator sets.
Solution
Do not operate or work on this product unless you have read and understood the instruction and warnings in the relevant Operation and Maintenance Manuals and relevant service literature. Failure to follow the instructions or heed the warnings could result in injury or death. Proper care is your responsibility. |
For the affected generator sets in field, the problem can be fixed by adding a jumper between pin 17 and pin 19 of the 9X-1339 Connector Receptacle As. This is not mandatory since diagnostic code 337-2 will not impact the operation of the affected generator sets.
