Diagnostic Procedure
EBS015CT
1.
CHECK OVERALL FUNCTION
1.
Start engine and let it idle.
2.
Make sure that turbocharger control actuator rod moves slightly
when engine is started.
OK or NG
OK
>> INSPECTION END
NG
>> GO TO 2.
2.
CHECK TURBOCHARGER BOOST CONTROL SOLENOID VALVE POWER SUPPLY CIRCUIT
1.
Disconnect turbocharger boost control solenoid valve harness
connector.
2.
Turn ignition switch ON.
3.
Check voltage between turbocharger boost control solenoid
valve terminal 2 and ground with CONSULT-II or tester.
OK or NG
OK
>> GO TO 3.
NG
>> Repair open circuit or short to ground or short to power
in harness or connectors.
3.
CHECK TURBOCHARGER BOOST CONTROL SOLENOID VALVE OUTPUT SIGNAL CIRCUIT FOR
OPEN AND SHORT
1.
Turn ignition switch OFF.
2.
Disconnect ECM harness connector.
3.
Check harness continuity between ECM terminal 6 and turbocharger boost control solenoid valve terminal
1. Refer to Wiring Diagram.
4.
Also check harness for short to ground and short to power.
OK or NG
OK
>> GO TO 4.
NG
>> Repair open circuit or short to ground or short to power in harness or connectors.

TURBOCHARGER BOOST CONTROL SOLENOID VALVE
1.
Disconnect turbocharger boost control solenoid valve harness
connector.
2.
Apply 12V direct current between turbocharger boost control solenoid valve terminals.
3.
Check air passage continuity of turbocharger boost control sole-
noid valve under the following conditions.
Operation takes less than 1 second.
If NG, replace turbocharger boost control solenoid valve.

BRAKE SWITCH
PFP:25230
Description
EBS016LL
STOP LAMP SWITCH
The stop lamp switch is installed to brake pedal bracket. The switch
senses brake pedal position and sends an ON-OFF signal to the
ECM. The ECM uses the signal to control the fuel injection control
system.
ASCD BRAKE SWITCH (MODELS WITH ASCD)
When depress on the brake pedal, ASCD brake switch is turned OFF and stop lamp switch is turned ON. ECM
detects the state of the brake pedal by this input of two kinds (ON/OFF signal)
Refer to
EC-653, "AUTOMATIC SPEED CONTROL DEVICE (ASCD)"
for the ASCD function.
CONSULT-II Reference Value in Data Monitor Mode
EBS016LM
Specification data are reference values.
ECM Terminals and Reference Value
EBS016LN
Specification data are reference values and are measured between each terminal and ground.
CAUTION:
Do not use ECM ground terminals when measuring input/output voltage. Doing so may result in dam-
age to the ECM's transistor. Use a ground other than ECM terminals, such as the ground.
