If one of the wires is faulty, the whole engine harness needs to be replaced, which is not something you will be able to do on your own, as the replacement part is not freely available. Possible causes of Because of this, you are always better off consulting service than attempting repairs on your own. Modern power generators, such as the ones made by Cummins, are very complex How To Fix Fault Code 1434 On Cummins Generator (Error Solved!). The trucks that were checked had measurements that were about 65 to 68 ohms on pins C and D of the 9 pin data link connector. There are affiliate links, so if you do decide to use any of them, Ill earn a small commission. Angel Chavez, you are dealing with a failure, design and verification tests failure really. There are several possible causes of the fault code 427, while some you might be able to fix on your own, others are better left to professionals. To determine the malfunction, you just need to write out the fault code from the device in the cab and find the codes in the table by selecting your own engine type. Step #4 Check CAN data link: The fault code 427 can happen because the CAN data link is interrupted either physically or electrically.
