2. Continuity test (between ``S'' terminal and ``M'' terminal).
+No continuity ... Replace.
PINION/CLUTCH CHECK
1. Inspect pinion teeth.
+Replace pinion if teeth are worn or damaged. (Also check con-
dition of ring gear teeth.)
2. Inspect reduction gear teeth (If equipped).
+Replace reduction gear if teeth are worn or damaged. (Also
check condition of armature shaft gear teeth.)
3. Check to see if pinion locks in one direction and rotates
smoothly in the opposite direction.
+If it locks or rotates in both directions, or unusual resistance is
evident. ... Replace.
BRUSH CHECK
Brush
Check wear of brush.
Wear limit length:
Refer to SDS (EL-51).
+Excessive wear ... Replace.
Brush spring pressure
Check brush spring pressure with brush spring detached from
brush.
Spring pressure (with new brush):
Refer to SDS (EL-51).
+Not within the speci®ed values ... Replace.
Brush holder
1. Perform insulation test between brush holder (positive side)
and its base (negative side).
+Continuity exists. ... Replace.
2. Check brush to see if it moves smoothly.
+If brush holder is bent, replace it; if sliding surface is dirty, clean.

Replacement
For removal and installation of spiral cable, refer to RS section
[``Installation Ð Air Bag Module and Spiral Cable'', ``SUPPLE-
MENTAL RESTRAINT SYSTEM (SRS)''].
+Each switch can be replaced without removing combination
switch base.
+To remove combination switch base, remove base attaching
screw.
+Before installing the steering wheel, align the steering wheel
guide pins with the screws which secure the combination switch
as shown in the left ®gure.

System Description
UNIFIED CONTROL METER
+Speedometer, odo/trip meter, tachometer, fuel gauge and water temperature gauge are controlled totally
by control unit combined with speedometer.
+Digital meter is adopted for odo/trip meter.*
*The record of the odo meter is kept even if the battery cable is disconnected. The record of the trip meter
is erased when the battery cable is disconnected.
+Odo/trip meter segment can be checked in diagnosis mode.
+Meter/gauge can be checked in diagnosis mode.
Note: Sub fuel gauge is not controlled by the control unit.
HOW TO CHANGE THE DISPLAY FOR ODO/TRIP METER
Note: Turn ignition switch to the ``ON'' position to operate odo/trip meter.

Flexible Print Circuit (FPC)
Tachometer, fuel gauge and water temperature gauge are con-
nected with uni®ed meter control unit (speedometer) by Flexible
Print Circuit (FPC) connector. When replace or remove and install
uni®ed control unit (speedometer), disconnect and connect FPC
connector according to the following steps.
DISCONNECT
1. Open connector cover.
2. Release connector lock by holding both ends of it and pulling it
up.
3. Disconnect FPC by pulling it up.
CONNECT
1. Insert FPC into connector and lock connector pushing FPC
downward.
2. Check secure connection of FPC.
3. Check continuity of check land terminal for secure connection
of FPC.
Resistance: 0W
4. Close connector cover.
