Engine Control Module (Bosch M5.2.1 - 1999-2000)

The remobilization strategy is the same as that described for 1996 Model Year Diesel vehicles. The BECM repeatedly transmits the remobilization code to the ECM at intervals of 144 ms. The code originates from the ECM with each ECM having a different code. If a new ECM or BECM is fitted, TestBook must be used to input the code to the BECM before the ignition is turned on.
