Generation condition
Idling speed adjustment potentiometer voltage remains higher than 4.6 V for 3
seconds.
Recoverability
System recovers when idling speed adjustment potentiometer voltage remains
4.6 V or less for 1 second.
Control effected by electronic control unit
• Control is effected with auto idle permanently selected.
• Actuator test “BA: VGT Test” is stopped.

Generation condition
Accelerator pedal switch remains ON for 1 second when accelerator pedal posi-
tion is higher than 30%.
Recoverability
System recovers if accelerator pedal switch is turned OFF when accelerator ped-
al position is 30% or lower.
Control effected by electronic control unit No specific control is effected.

Generation condition Magnetic valve power supply remains low for 0.5 second.
Recoverability
System recovers (power is re-supplied to electronic control unit) if signal becomes
normal when starter switch is turned OFF (2 minutes or more) → ON.
Control effected by electronic control unit
• Turbocharger magnetic valve control is stopped.
• Safety relay control is stopped.
• Powertard magnetic valve control is stopped.
• Electronic drive unit relay control is stopped.
• Following controls are stopped by stopping electronic drive unit relay control.
• Exhaust gas recirculation control is stopped.
Inspection Other
Replace engine electronic control unit. (See “6. Registration or Change of the
Engine Electronic Control Unit Information”.)
Generation condition
Diagnosis code is generated under either of the following conditions.
• No controller area network signals from multi function vehicle control unit are
received for 1.8 seconds.
• Controller area network signal from MVCU indicating “vehicle speed limitation
device (SLD) is abnormal” is received.
Recoverability
System recovers (power is re-supplied to electronic control unit) if signal becomes
normal when starter switch is turned OFF (2 minutes or more) → ON.
Control effected by electronic control unit
• Engine speed is limited.
• Vehicle speed limiting control is stopped.
