Control Module Coding (LH and EZL/AKR)
LH CONTROL MODULE CODING
There are two LH control modules used to operate this engine management system. The right LH control module (N3/2) operates cylinders 1 to 6.
The left LH control module (N3/2) operates cylinders 7 to 12. In order to differentiate between the left and right control module program, the left
control module (N3/2) is connected to ground (coded) at connection (1.2).
EZL/AKR CONTROL MODULE CODING
There are two EZL/AKR control modules used to operate this engine management system. If the EZL/AKR control module socket "6" is not
connected to ground, it operates cylinders 1 to 6. If the EZL/AKR control module socket "6" is connected to ground, it operates cylinders 7 to 12.
