CVT SHIFT LOCK SYSTEM

CVT SHIFT LOCK SYSTEMPFP:00000
DescriptionBCS001MP

The electrical key interlock mechanism also operates as a shift lock:
With the ignition switch turned to ON, the selector lever cannot be shifted from “P” (parking) to any other
position unless the brake pedal is depressed.
With the key removed, the selector lever cannot be shifted from “P” to any other position.
The key cannot be removed unless the selector lever is placed in “P”.

The shift lock and key interlock mechanisms are controlled by the ON-OFF operation of the shift lock sole-
noid and by the operation of the rotator and slider located inside the key cylinder, respectively.
Shift Lock System Electrical Parts LocationBCS001MQ
NOTE:
This emergency lever can be used when battery is off ignition key cannot be removed. In the situation like this,
by operating this lever, ignition key can be removed.

SHIFT LOCK HARNESS CONNECTOR TERMINALS LAYOUT
SHIFT LOCK CONTROL UNIT INSPECTION TABLE
Shift lock control unit terminal data are reference values, measured between each terminal and ground.
NOTE:
Take care that the pointer of circuit tester swings only momentarily because the output time is so short. If the inspection is done with an
oscilloscope, it should be observed that the power source voltage lasts for 3.5 to 10 ms.

COMBINATION METERS

COMBINATION METERSPFP:24814
System DescriptionBKS001RX
UNIFIED METER CONTROL UNIT

Speedometer, odo/trip meter, tachometer and fuel gauge are controlled by the unified meter control unit,
which is built into the combination meter. Unified meter control unit receives signals from unified meter
and A/C amp.

Warning lamp and indicator lamp of combination meter are controlled by signals drawn from the unified
meter and A/C amp.

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 and shift indicator segments can be checked in diagnosis mode.

Meters/gauges can be checked in diagnosis mode.
Illumination control

Unified meter control unit produces an illumination output of the
combination meter when the ignition switch is “ON”.

Light levels can be adjusted by pressing illumination control
switch of the combination meter when lighting switch is “ON”.

Illumination control switch has five light level settings.
NOTE:
When it is light outside, light level cannot be adjusted by turning
on the lighting switch.

SELF-DIAGNOSIS MODE FUNCTION

Odo/trip meter segment and shift indicator segment operation can be checked in self-diagnosis mode.

Meter/gauge can be checked in self-diagnosis mode.
OPERATION PROCEDURE
1. Turn the ignition switch ON, and switch the odo/trip meter to “trip A” or “trip B”.
NOTE:
If the diagnosis function is activated with the “trip A” displayed, the mileage on the “trip A” will indicate
0000.0, but the actual trip mileage will be retained. (Trip same way for “trip B”.)
2. Turn ignition switch OFF.
3. While pushing the odo/trip meter switch, turn ignition switch ON again.
4. Make sure that the trip meter displays “0000.0”.
