Checking of CVT PositionBCS001MO
1. Place selector lever in “P” position, and turn ignition switch ON. (Do not start engine.)
2. Make sure selector lever can be shifted to other than “P” position when brake pedal is depressed. Also
make sure selector lever can be shifted from “P” position only when brake pedal is depressed.
3. Move the selector lever and check for excessive effort, sticking, noise or rattle.
4. Confirm the selector lever stops at each position with the feel of engagement when it is moved through all
the positions. Check whether or not the actual position the selector lever is in matches the position shown
by the shift position indicator and the transaxle body.
5. The method of operating the lever to individual positions cor-
rectly should be as shown in the figure.
6. Confirm the back-up lamps illuminate only when lever is placed
in the “R” position. Confirm the back-up lamps do not illuminate
when the selector lever is pushed toward the “R” position side
with the gear position remained in the “P” or “N” position.
7. Confirm the engine can only be started with the selector lever in
the “P” and “N” positions.
8. Make sure transaxle is locked completely in “P” position.
9. When selector lever is set to manual shift gate, make sure man-
ual mode is displayed on combination meter.
Shift selector lever to “+” and “-” sides, and make sure set shift position changes.

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 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.

Multiport Fuel Injection (MFI) SystemBBS005BF
INPUT/OUTPUT SIGNAL CHART
*1: This sensor is not used to control the engine system under normal conditions.
*2: This signal is sent to the ECM through CAN communication line.
*3: ECM determines the start signal status by the signals of engine speed and battery voltage.
SYSTEM DESCRIPTION
The amount of fuel injected from the fuel injector is determined by the ECM. The ECM controls the length of
time the valve remains open (injection pulse duration). The amount of fuel injected is a program value in the
ECM memory. The program value is preset by engine operating conditions. These conditions are determined
by input signals (for engine speed and intake air) from both the crankshaft position sensor and the mass air
flow sensor.
VARIOUS FUEL INJECTION INCREASE/DECREASE COMPENSATION
In addition, the amount of fuel injected is compensated to improve engine performance under various operat-
ing conditions as listed below.
<Fuel increase>

During warm-up

When starting the engine

During acceleration

Hot-engine operation

When selector lever is changed from N to D

High-load, high-speed operation
<Fuel decrease>

Major Sensor Reference Graph in Data Monitor ModeBBS005CA
The following are the major sensor reference graphs in “DATA MONITOR” mode.
CLSD THL POS, ACCEL SEN 1, THRTL SEN 1
Below is the data for “CLSD THL POS”, “ACCEL SEN 1” and “THRTL SEN 1” when depressing the accelera-
tor pedal with the ignition switch ON and with selector lever in D position.
The signal of “ACCEL SEN 1” and “THRTL SEN 1” should rise gradually without any intermittent drop or rise
after “CLSD THL POS” is changed from “ON” to “OFF”.
ENG SPEED, MAS A/F SE-B1, THRTL SEN 1, HO2S2 (B1), HO2S1 (B1), INJ PULSE-B1
Below is the data for “ENG SPEED”, “MAS A/F SE-B1”, “THRTL SEN 1”, “HO2S2 (B1)”, “HO2S1 (B1)” and
“INJ PULSE-B1” when revving engine quickly up to 4,800 rpm under no load after warming up engine suffi-
ciently.
Each value is for reference, the exact value may vary.
