Information concerning B4184S and B4204S

From and including May 1997 there is only one replacement part engine control module (ECM) for each type of engine. These engine control modules (ECM) applies to both cars without, and for earlier cars, cars with pulsed secondary air injection system (PAIR) pump.

The engine control module (ECM) no longer controls the secondary air injection system (PAIR) pump when it is fitted to cars with manual transmission and pulsed secondary air injection system (PAIR) pump.

These cars however still meet the statutory requirement for emission levels.
