Current flowing in the turbocharger magnetic valve (No. 1 magnetic valve) re-
mains above the specified value for 1 second.
System recovers when current flowing in the turbocharger magnetic valve (No.
1 magnetic valve) becomes normal for 1 second.
• Turbocharger control is stopped.
• Exhaust gas recirculation control is stopped.
• Auto cruise control is stopped.
• Injection quantity is limited. (Output is reduced, and exhaust emissions wors-
en.)
• Actuator test "BA: VGT Test" is stopped.

#566: Turbocharger magnetic valve
Turbocharger magnetic valve (No. 1 magnetic valve) system
Turbocharger magnetic valve (No. 1 magnetic valve) circuit shorted to ground
or open-circuited (low level when turned OFF) as detected for 1 second.
System recovers when current flowing in the turbocharger magnetic valve (No.
1 magnetic valve) becomes normal (high level when turned OFF) for 1 second.
• Turbocharger control is stopped.
• Exhaust gas recirculation control is stopped.
• Auto cruise control is stopped.
• Injection quantity is limited. (Output is reduced, and exhaust emissions wors-
en.)
• Actuator test "BA: VGT Test" is stopped.
