+When electrolyte temperature is 35ÉC (95ÉF) and speci®c grav-
ity of electrolyte is 1.230, converted speci®c gravity at 20ÉC
(68ÉF) is 1.240.

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.
