This step will only work if you use Cummins Insite (version 8.5.2 or later) or an equivalent diagnostic tool which supports the test described below. Diesel emissions systems rely on sensors to send signals to control modules when maintenance on the aftertreatment systems is required or when something is no longer functioning properly and requires a repair. You can buy vacuum pumps online or from auto part stores. Just in case anyone's searching for the values, MES is showing the following:-. Consult the wiring diagram and check the wires. ARghh.. Not again.. The more complex, the better! whether or not its possible id definitely appreciate any help as i dont know about resistors and would definitely like to try this out was thinking of wiring up something to a set of switches that when flipped it will progressively fool the sensor into thinking the filter is actively cleaning or becoming blocked.
