P1278: EGR3 (warning lamp: 69)
P1625: EDU Relay (warning lamp flashes: 84)
P1630: CAN (EGR 1) (warning lamp flashes: 95)
Generation condition
Controller area network signal from exhaust gas recirculation electronic drive unit
indicating “magnetic valve (M/V-3) circuit shorted to power source” remains being
received for 2 seconds.
Recoverability
System recovers if controller area network signal from exhaust gas recirculation
electronic drive unit indicating “magnetic valve (M/V-3) is normal” remains being
received for 1 second.
Control effected by electronic control unit
Exhaust gas recirculation control is stopped.

Exhaust gas recirculation magnetic valve system
Generation condition
Either of the following occurs.
(1) Current flowing in the electronic drive unit relay remains exceeds the speci-
fied value for 1 second.
(2) Electronic drive unit relay circuit remains shorted to ground or open (driving
terminal low level when turned OFF) as detected for 1 second.
(3) Electronic drive unit relay circuit remains shorted to power supply (high level
when turned ON) as detected for 1 second.
Recoverability
•
In the case of above problem (1)
•
System recovers if current flowing in the electronic drive unit relay remains
lower than the specified value.
•
In the case of above problem (2)
•
System recovers if current flowing in the electronic drive unit relay remains
normal (driving terminal high level when turned OFF) for 1 second.
•
In the case of above problem (3)
•
System recovers if current flowing in the electronic drive unit relay remains
normal (driving terminal low level when turned ON) for 1 second.
Control effected by electronic control unit
Exhaust gas recirculation control is stopped.

Generation condition
Any of the following occurs.
(1) Controller area network signal from exhaust gas recirculation electronic drive
unit 1 indicating “target exhaust gas recirculation opening received from en-
gine electronic control unit is wrong” remains being received for 2 seconds.
(2) No controller area network signal from exhaust gas recirculation electronic
drive unit is received for 1 second.
(3) Engine controller area network signal abnormal state lasts for 0.5 second.
Recoverability
•
In the case of above problem (1)
•
System recovers if controller area network signal from exhaust gas recircu-
lation electronic drive unit 1 indicating “target exhaust gas recirculation
opening received from engine electronic control unit is normal” remains be-
ing received for 1 second.
•
In the case of above problem (2)
•
System recovers if controller area network signal from exhaust gas recircu-
lation electronic drive unit remains being received for 0.5 second.
•
In the case of above problem (3)
•
System recovers if normal engine controller area network signal lasts for
0.5 second.
Control effected by electronic control unit
Exhaust gas recirculation control is stopped.
