Troubleshooting
13A-93
INSPECTION PROCEDURE 32
Stop lamp switch system
Probable cause
The engine-ECU determines whether the brake pedal is depressed or not, by means
of the stop lamp switch input signal.
Malfunction of the stop lamp switch
Open circuit or short-circuited harness wire in the
stop lamp circuit, or poor connector contact
Malfunction of the engine-ECU
NG
Replace the engine-ECU.
OK
Check trouble symptom.
OK
Check the following connector: C-18
NG
Repair
NG
Check the harness wire between the engine-ECU and stop lamp,
and repair if necessary.
NG
Repair
OK
Check trouble symptom.
NG
Check the following connectors: C-02, C-04, C-28
OK
Measure at engine-ECU connector C-18.
Disconnect the connector, and measure at the harness side.
Voltage between terminal 63 and earth
(Ignition switch: ON)
OK: 0 – 3 V (when the brake pedal is not depressed)
System voltage (when the brake pedal is depressed)
NG
Check the harness wire between the battery and stop lamp switch.
NG
Repair
OK
Check trouble symptom.
NG
Check the following connector: C-29
OK
Measure at stop lamp switch connector C-04.
Disconnect the connector, and measure at the harness side.
Voltage between terminal 2 and earth
OK: System voltage
Check the stop lamp switch. (Refer to GROUP 35 – Brake Pedal.)
NG
Replace
INSPECTION PROCEDURE 33
Small lamp switch system
Probable cause
The engine-ECU determines whether the small lamp switch is on or off.
According to that information, the engine-ECU controls alternator output current
when the vehicle is started.
Improper connector contact, open circuit or
short-circuited harness wire in the taillamp circuit
Malfunction of the engine-ECU
NG
Replace the engine-ECU.
OK
Check the trouble symptoms.
OK
Check the following connector: C-19
NG
Repair
Measure at the engine-ECU connector C-19.
Disconnect the connector, and measure at the harness
side.
Voltage between 88 and earth
(Lighting switch: ON)
OK: System voltage
NG
Check the taillamp circuit. (Refer to ELECTRICAL WIRING.)

DATA LIST REFERENCE TABLE
Caution
When shifting the select lever to D range, the brakes should be applied so that the vehicle does
not move forward.
NOTE
*
1
: Within four minutes after starting the engine
*
2
: In a new vehicle [driven approximately 500 km or less], the injector drive time is sometimes 10 %
longer than the standard time.
*
3
: The accelerator pedal position switch normally turns off when the voltage of the accelerator pedal
position sensor (1st channel) is 200 – 600 mV higher than the voltage at the idle position. If the accelerator
pedal position switch turns back on after the accelerator pedal position sensor voltage has risen by
100 mV and the throttle valve has opened, the accelerator pedal position switch and the accelerator
pedal position sensor (1st channel) need to be adjusted.
