Remove adblue on Terex XR400
We were faced with a recurring adblue problem on a Terex crusher. The machine went into degraded mode and it was no longer possible to crush. After Scania had replaced several parts, it turned out that the problem was still there, and the money lost was colossal when the machine wasn't running. The aim of our intervention was to reprogram the entire EMS S8 system in order to eliminate the problem once and for all.
How do I remove the adblue?
Let's start by noting the fault codes present on the machine and using our tools. Scania's SPN codes, the machine's own SPN codes and the description of the problem will help us pinpoint the problem. However, all the fault codes relating to the Adblue system will be eliminated, but to be on the safe side, we'll make a note of those currently present to remove them from memory and override their ACTIVE status.
Dismantling the engine ECU and reprogramming Adblue parameters
Once all the codes have been memorized and identified, we move on to reprogramming. This part of the work involves modifying all the engine parameters, shunting the Adblue system electronically, removing the LIMP mode relating to emissions (restricted power mode)... Programming is done on the table, as there is no OBD diagnostic socket on the vehicle. (We now have an adaptor of our own design, which means we don't have to dismantle the engine box for future servicing.
After Adblue reprogramming on Terex XR400 ?
Once the system has been reprogrammed, we reinstall the engine ECU in its place. We take care to test the machine and check that all data are ok, and that the Adblue faults previously present are now inactive. Below is the machine running at 1600rpm with no loss of power or error messages.
