Vehicles with EZS control unit without column sleeve module (MRM)
The signals from the push-button switch for the cruise control are detected by the control unit EIS and
transmitted to the CAN data bus.
Vehicles without EZS control unit
The signals from the cruise control switch are transmitted directly to the engine control unit.
Vehicles with manual transmission (MT)
Cruise control remains active during gear change, in other words the cruise control is not switched off when the
clutch is operated.
Traction systems control unit
Transmits the vehicle speed signal via CAN to the ME control unit.

TESTING
Starter malfunctions may cause a Di agnostic Trouble Codes (DTCs) to be stored in Motor Electronics
Sequential Fuel Injection (ME-SFI) sy stem. After repairs are completed check for and erase any DTCs stored in
(ME-SFI) system. See appropriate SE LF-DIAGNOSTICS article in ENGINE PERFORMANCE. If cause of
starter malfunction is not engine pe rformance related, replace starter.
REMOVAL & INSTALLATION
STARTER
Removal & Installation
1. Disconnect and shield negative battery cable. See BATTERY DISCONNECT/CONNECT under
SERVICE PRECAUTIONS.
2. Remove nut (2) for inner fender. See Fig. 5
. Pull front and rear section of inner fender (1) downward.
Move inner fender away inward and downward. Pull toward outside over wheel. DO NOT damage fender
cutout or paint.
3. On vehicles with 112 engine, remove nut (6) at shield (5) of left engine mount and take out shield. See
Fig. 6
.
4. On all vehicles, disconnect circuit 30 (1) and circuit 50 (2) cables from starter. See Fig. 6
. Remove bolts
(3) for starter-to-crankcase. Take starter (M1) out to the side.
5. If replacing starter on vehicles with manual transmission, check ring gear at flywheel for wear and
damage. If replacing starter on vehicles with auto matic transmission, check ring gear on drive plate for
wear and damage. Repair or repl ace damaged parts as necessary.
6. To install, reverse removal proce dure. Replace bolts with locking splines, micro-encapsulated bolts and
self-locking nuts. Mating thread of mi cro-encapsulated bolts must be cleaned to remove all residue of old
bolt locking compound. Tighten fasteners to specification. See TORQUE SPECIFICATIONS
. Connect
battery. See BATTERY DISCONNECT/CONNECTunder SERVICE PRECAUTIONS.
