Preparation For Test

Preliminary work:
Diagnosis - Diagnostic Trouble Code (DTC) Memory. Diagnostic Trouble Code (DTC) Memory

Preparation for Test:
1. Check fuses F1-13, F1-14, F1-22, F4-3, F4-8, F4-9, F4-13, F4-14 OK.
2. Check fuse F4-8, F4-9 for left front ESA control module (N32/1) OK.
3. Check fuse F4-13, F4-14 for right front ESA control module (N32/2) OK.
4. Battery voltage 11-14 V,
5. Connect Hand-Held Tester (HHT) to 38-pole data link connector (X11/4) according to connection diagram. Connecting Tester Or Scanner, Reading and Erasing DTC Memory
6. Prior to each connection or disconnection of connectors at the combination control module (N10-1), the battery ground cable must be disconnected (fault codes will be erroneously stored in DTC memory).

See Electrical Wiring Diagrams.

NOTE: The diagnostic trouble codes (DTC's) can only be read out and erased using the Hand-Held Tester (HHT).

Head Restraint Initial Adjustment:
Prerequest for the proper operation of the head restraint is that the head restraint be operated once to its lower adjustment stop and once to its upper adjustment stop.

Left Front Power Seat and Front Passenger Seat Memory:
The left/right front ESA control modules contain a memory for both the left front power seat and front passenger seat.

Components:
The left/right front ESA control modules (N32/1, N32/2), as well as the various motors of the left/right ESA motor group (M27, M28) are of like design and can be interchanged with each other.

When changing a left/right front ESA control module (N32/1, N32/2), the seat adjustment motor supplier (Brose/Hammerstein) must be programmed into the ESA control module.
