Ecu - Volvo ECS Training Tips And Tactics

ECS Gen. 3
ECS ECU
The external appearance of Gen. 3 ECS ECU is identical to
that used with Gen. 2.
Internally there is new hardware and software.
Provided that the correct adapted software and data sets
are loaded, the Gen. 3 unit will work with Gen. 1 and
Gen. 2 systems.
So, using the correct software and data sets, a Gen. 3 ECU
can be used to replace a faulty Gen.1 or Gen. 2 ECU.
Note: The new software does not work with earlier ECUʼs.
