DTC P1623 INJECTOR ADJUSTMENT VALUEPFP:23710
DescriptionEBS01KKP
Injector adjustment value indicates manufacturing tolerance and the value is printed on the top of fuel injec-
tor.The injector adjustment value which is correctly stored in ECM is needed for precise fuel injection control.
A performance of emission control and a drivability may effect when there is a mismatch between the following
two values.
lThe injector adjustment value stored in ECM
lThe injector adjustment value of the fuel injector which is installed on the vehicle
On Board Diagnosis LogicEBS01KKQ
The MI will not light up for this self-diagnosis.
NOTE:
This DTC is not detected when injector adjustment value (not correct but existent) is stored in ECM.
DTC Confirmation ProcedureEBS01KKR
NOTE:
If DTC Confirmation Procedure has been previously conducted, always turn ignition switch OFF and wait at
least 10 seconds before conducting the next test.
WITH CONSULT-II
1. Turn ignition switch ON.
2. Select “DATA MONITOR” mode with CONSULT-II.
3. Wait at least 5 seconds.
4. If DTC is detected, go toEC-274, "
Diagnostic Procedure".
WITHOUT CONSULT-II
1. Turn ignition switch ON and wait at least 5 seconds.
2. Turn ignition switch OFF, wait at least 10 seconds and then turn ON.
3. Perform Diagnostic Test Mode II (Self-diagnostic results) with ECM.
Example: Injector adjustment value = D021ABCD1A061234000000000000E6

Diagnostic Procedure
EBS01KM2
1.CHECK OVERALL FUNCTION
1. Start engine and let it idle.
2. Make sure that turbocharger control actuator (1) 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. Turn ignition switch OFF.
2. Disconnect turbocharger boost control solenoid valve (1) har-
ness connector.
–: Vehicle front
–Alternator (2)
3. Turn ignition switch ON.

BRAKE SWITCH
BRAKE SWITCH
PFP:25230
DescriptionEBS01KML
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 toEC-355, "
AUTOMATIC SPEED CONTROL DEVICE (ASCD)"for the ASCD function.
CONSULT-II Reference Value in Data Monitor ModeEBS01KMM
Specification data are reference values.
ECM Terminals and Reference ValueEBS01KMN
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.
