P1C13: Injector #3-A (Plausibility) (warning lamp flashes: 39)
P1C14: Injector #4-A (Plausibility) (warning lamp flashes: 8)
P2002: DPF MFF (warning lamp flashes: 55)

Generation condition
The engine electronic control unit has judged that injector magnetic valve (for No.
3 cylinder) was faulty in comparison with the condition of other injector magnetic
valves.
Recoverability
System recovers if any valid signal is input when starter switch is turned from
OFF to ON (the warning lamp does not extinguish unless 3 consecutive valid sig-
nals are input).
Control effected by electronic control unit
• Fuel injection amount is limited to a default value.
• Occurrence of abnormal injection control is communicated through CAN.
• Injector magnetic valve (for No. 2 and No. 3 cylinders) is deactivated.
• Exhaust gas recirculation control is deactivated.
• Throttle control is deactivated.
Possible causes
• Open-circuited or short-circuited harness between engine electronic control
unit and injector magnetic valve (No. 3 cylinder)
• Malfunction of each connector
• Malfunction of injector magnetic valve (No. 3 cylinder)
• Malfunction of engine electronic control unit
Generation condition
The engine electronic control unit has judged that injector magnetic valve (for No.
4 cylinder) was faulty in comparison with the condition of other injector magnetic
valves.
Recoverability
System recovers if any valid signal is input when starter switch is turned from
OFF to ON (the warning lamp does not extinguish unless 3 consecutive valid sig-
nals are input).
Control effected by electronic control unit
• Fuel injection amount is limited to a default value.
• Occurrence of abnormal injection control is communicated through CAN.
• Injector magnetic valve (for No. 1 and No. 4 cylinders) is deactivated.
• Exhaust gas recirculation control is deactivated.
• Throttle control is deactivated.
Possible causes
• Open-circuited or short-circuited harness between engine electronic control
unit and injector magnetic valve (No. 4 cylinder)
• Malfunction of each connector
• Malfunction of injector magnetic valve (No. 4 cylinder)
• Malfunction of engine electronic control unit
Generation condition
Diesel particulate filter differential pressure is determined to exceed the pro-
grammed value.
Recoverability
System recovers if any valid signal is input when starter switch is turned from
OFF to ON (the warning lamp does not go out unless 3 consecutive valid signals
are input).
Control effected by electronic control unit Injection quantity is limited.
Possible causes • Clogged diesel particulate filter
Generation condition Throttle electronic drive unit judges intake throttle open-circuited.
Recoverability
System recovers if any valid signal is input when starter switch is turned from
OFF to ON (the warning lamp does not go out unless 3 consecutive valid signals
are input).
Control effected by electronic control unit
• Injection quantity is limited.
• Exhaust gas recirculation control is stopped.
• Throttle control is stopped.
Possible causes
• Open-circuited or short-circuited harness between electronic drive unit and in-
take throttle
• Malfunction of each connector
• Malfunction of motor (built in intake throttle)
• Malfunction of throttle position sensor (built in intake throttle)
• Malfunction of electronic drive unit
• Malfunction of electronic drive unit relay
