SRC – ACM

ADBlue/SCR Removal Disable AdBlue & ACM – After treatment Control Module

For better control of exhaust work, some manufacturers use separate Aftertreatment Control Module (ACM). The role to control AdBlue tank sensors, heaters, urea pumps, SCR injectors, DPF sensors, exhaust flaps and brakes.
So when any of that components will be broken – ACM starts showing a fault and force ECU to use a limp mode. That”s why this unit required to reflash and fix broken parts (DPF, SCR and sometime EGR sensors) or in some cases possible to disable whole unit in ECU (with lost all functions – including DEF level and exhaust brake).
So if required to make a full kit of disabling DPF SCR EGR – we can take off ACM and disable all of that work.
Not possible to make ACM off because it monitored by several units and dash show a fault messages
Bosch EDC7, TRW EMS2.3-2.4,Transtron ,MB MCM2.1.

ACM types that supported to reflash:
Bosch DCU15-17
Adem A4-A5
Motorola CM2220-2350 ACM
Denso ACM Kubota, New Holland
Continental ACM for Mercedes MCM2x / Volvo / Scania EEC3

ACM off should be performed at clear dash
when all faults from this unit erased or repaired.
If not possible to clear – try to take off battery for 15-20min or use resistor on broken sensors.
