Injector magnetic valve (No. 2 cylinder) is short-circuited, open-circuited or over-
loaded.
• When short-circuited or overloaded
• 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.
• When open-circuited
• System recovers if signal becomes normal with starter switch in ON posi-
tion.
• Exhaust gas recirculation control is stopped.
• Injector magnetic valves (No. 1, 2 and 3 cylinder) are stopped.
(Output is reduced, and exhaust emissions worsen.)
• Auto cruise control is stopped.
• Actuator test "BA: VGT Test" is stopped.

Injector magnetic valve (No. 2 cylinder) system
Injector magnetic valve (No. 4 cylinder) is short-circuited, open-circuited or over-
loaded.
• When short-circuited or overloaded
• 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.
• When open-circuited
• System recovers if signal becomes normal with starter switch in ON posi-
tion.
• Exhaust gas recirculation control is stopped.
• Injector magnetic valves (No. 4, 5 and 6 cylinder) are stopped.
(Output is reduced, and exhaust emissions worsen.)
• Auto cruise control is stopped.
• Actuator test "BA: VGT Test" is stopped.
BE: Injector Test 4

Injector magnetic valve (No. 4 cylinder) system
Engine speed is 2900 rpm or higher.
System recovers if engine speed is 2500 rpm or less.
• No feed from MPROP (rail pressure control valve)
• Exhaust gas recirculation control
• Auto cruise control is stopped.
• Turbocharger control is stopped.
• Check for occurrences of diagnosis code "P0335: Engine Revolution SNSR".
• If the diagnosis code is redisplayed with the pointer of the tachometer not
reaching the red zone, replace the engine electronic control unit.
