SPN FMI DTC SYMPTOM/CAUSE RECOVERY FROM ERROR
4765 4
Exhaust gas temperature
sensor 0: Low
Open circuit or +B short circuit of sen-
sor/harness. DOC inlet temperature
sensor voltage 0.08V or less.
Key switch turn OFF.
523523 2
Injector drive circuit open
in Nos. 1 & 4 cylinder
simultaneously.
Wiring harness open circuit. Injectors
that have no DTC are operated. En-
gine vibration increases and may stop.
Key switch turn OFF.
523523 3
Nos. 1 & 4 cylinder injec-
tor short to +B at power
supply side, or all cylinder
injectors short to +B.
Wiring harness short to +B. Injectors
that have no DTC are operated. En-
gine vibration increases and may stop.
Key switch turn OFF.
523523 4
Nos. 1 & 4 cylinder injector
short to ground at power
supply side, or all cylinder
injectors short to ground.
Wiring harness short to ground. Injec-
tors that have no DTC are operated.
Engine vibration increases and may
stop.
Key switch turn OFF.
523524 2
Injector drive circuit open
in Nos. 2 & 3 cylinder
simultaneously.
Wiring harness open circuit. Injectors
that have no DTC are operated. En-
gine vibration increases and may stop.
Key switch turn OFF.
523524 3
Nos. 2 & 3 cylinder injec-
tor short to +B at power
supply side, or all cylinder
injectors short to +B.
Wiring harness short to +B. Injectors
that have no DTC are operated. En-
gine vibration increases and may stop.
Key switch turn OFF.
523524 4
Nos. 2 & 3 cylinder injec-
tor short to ground at
power supply side, or all
cylinder injectors short to
ground.
Wiring harness short to ground. Injec-
tors that have no DTC are operated.
Engine vibration increases and may
stop.
Key switch turn OFF.
523525 1
Injector charge voltage
low.
Injector charge voltage low. Failure
of charge circuit of ECU. Engine may
stop.
Key switch turn OFF.
523527 2 ECU monitoring error.
Failure of monitoring IC of CPU. En-
gine stops.
Key switch turn OFF.
523535 0
Injector charge voltage:
High
EGR stops. Engine forcibly stops 60
seconds later.
Key switch turn OFF.
523536 2 EGR feedback error.
DC motor feedback control error. Dur-
ing wrong duty feedback, activation of
restoration will repeat 30 times. If the
restoration was not successfully com-
pleted, it will be judged as a feedback
error. EGR stops.
Diagnostic counter = zero
523537 2
EGR DC motor tempera-
ture error.
Estimated temperature is 113° F (45°
C) or above. EGR stops.
Diagnostic counter = zero
523538 2 QR data error.
QR data read error from EEPROM.
Nozzle correction is not executed.
Key switch turn OFF.
