900 L4-2118cc 2.1L DOHC (1992)
Engine Control Module: Description and Operation
Control Module (LH 2.4.2)
Control module (LH 2.4.2)
The LH 2.4.2 control module is adapted to system changes resulting from changed components but also contains software changes which affect other
additional functions.
Engagement of the Lambda sensor when the engine is started from cold is a function of time instead of temperature as it was before. This means that
the theoretical limit at which control can start is reduced from 16°C to 0°C.
AC engagement is governed by the LH control module.
The AC relay is discontinued.
