Preparation For Test

1. Complete preliminary work.
2. Ignition OFF.
2. Remove LH-SFI control module (N3/1).
3. Connect socket box with contact module 140 589 02 63 00 and contact box to LH-SFI control module (N3/1) according to connection diagram.
4. Test steps 1.2,1.3, 2.2 - 2.5, 4 and 36 only!
- Ignition OFF.
- Remove base module (N16/1) and connect socket box with contact module 140 589 01 63 00 and contact box to base module.

NOTE:
- When performing test and adjustment work, the engine rpm should only be raised using the accelerator pedal. If the engine speed is raised via the control linkage in the engine compartment, the "limp-home" mode will become active and will be registered in the electronic accelerator malfunction memory as a fault. The acceleration slip regulation (ASR) malfunction indicator lamp will also come on.
- If installing a LH-SFI control module from another vehicle, the control module's self-adaptation feature must be reset to its mean value.
- The numbers indicated in parentheses in the "Test Connection" column, for example, (1.23) signify:
1 = Connector 1 in wiring diagram
23 = Socket 23 in wiring diagram
