2011 Volvo D13 STOP engine fault


I doubt any used truck will have the bugs worked out of it.

Not even one an o/o had traded in. Namely because by the time they've decided to trade it off, they've decided to stop spending any money on fixing it except the absolute must do to keep it legal.
 
I have a 2011 volvo, D13 engine, I-Shift, and while pulling the trailer uphill, I keep getting the Stop Engine Fault message. Everytime I pull over, I stop the engine, pop the hood and I can see the coolant boiling but the water temperature gauge doesn't go over 200degrees. I had it in 3different Volvo dealerships, they replaced The EGR cooler, they tested the truck but didn't get any error on the computer. They also changed the thermostat. About a month ago I had the water pump replaced, the coolant tank and all the hoses and I have no leak whatsoever. Probably not related, but I also get a message on dashboard saying 'tractor front parking light open circuit' and other Check lights messages. I have no issues when bobtailing. Any ideas on what the problem might be? Thank you.


Volvo FH12 with engine D12A Fault Codes
Code Description Cause and response.



11 Accelerator pedal. Faulty sensor of the accelerator pedal or damaged wiring between the motor and pedal control unit. Incomplete accelerator pedal possible sharp increase in engine speed.

Idling switch 12 of the accelerator pedal. Faulty sensor of the accelerator pedal or damaged wiring between the motor and pedal control unit. accelerator pedal depression does not respond.

13 Vehicle speed signal. Faulty wiring, faulty instrument cluster is faulty Tachograph. Cruise control does not work until the fault code is active.

14 relay power the engine control unit. Faulty relay or damaged wiring.

21 Internal fault in the engine control unit. Defective engine control unit. Cruise control does not work.

22 Program error in the engine control unit. Do not programmed or programmed with errors the engine control unit. The engine will not start.

23, the coolant temperature sensor. Faulty sensor wiring is damaged, the water pump is working part-time performance, packed with honeycomb radiator or faulty thermostat.

24 Temperature of combustion air. Faulty sensor wiring damaged, clogged honeycomb intercooler (intercooler), mechanical malfunction of the engine. At a temperature of combustion air above 91 ° C lamp "Check Engine" lights steadily, and the engine power will be reduced. In the event of a fault in the wiring harness or the defective sensor lamp "Check Engine" will blink.

25 The pressure of the charge air. Faulty sensor wiring damaged defective turbocharger is damaged or clogged intercooler, engine mechanical fault. Reduced engine power, increased exhaust emissions.

26 camshaft speed sensor. Faulty sensor camshaft speed, damaged wiring, broken synchronization between the signals from the speed sensor and camshaft rotation of the crankshaft sensor. In case of violation of synchronization codes will be active on 26 and 27 simultaneously. Engine runs for a long time or may not start on the first try.

The sensor 27 of the engine speed. Faulty sensor engine speed, damaged wiring, broken synchronization between the signals from the speed sensor and camshaft rotation of the crankshaft sensor. In case of violation of synchronization codes will be active on 26 and 27 simultaneously. Engine runs for a long time or may not start on the first try.

31 Pump-injector cylinder №1. Faulty unit injector, damaged wiring between engine control unit and the pump -forsunkoy, mechanical failure in the engine. The engine does not operate smoothly, it can be increased opacity of the exhaust gases.

32 №2 cylinder pump injector. Faulty unit injector, damaged wiring between engine control unit and the pump -forsunkoy, mechanical failure in the engine. The engine does not operate smoothly, it can be increased opacity of the exhaust gases.

33 Pump-injector cylinder №3. Faulty unit injector, damaged wiring between engine control unit and the pump -forsunkoy, mechanical failure in the engine. The engine does not operate smoothly, it can be increased opacity of the exhaust gases.

34 №4 cylinder pump injector. Faulty unit injector, damaged wiring between engine control unit and the pump -forsunkoy, mechanical failure in the engine. The engine does not operate smoothly, it can be increased opacity of the exhaust gases.

35 №5 cylinder pump injector. Faulty unit injector, damaged wiring between engine control unit and the pump -forsunkoy, mechanical failure in the engine. The engine does not operate smoothly, it can be increased opacity of the exhaust gases.

36 №6 cylinder pump injector. Faulty unit injector, damaged wiring between engine control unit and the pump -forsunkoy, mechanical failure in the engine. The engine does not operate smoothly, it can be increased opacity of the exhaust gases.

Information codes (are not the fault codes).

Code Description Reaction

41 Do not carry out a check of brakes or faulty brake pedal. It does not work and the cruise control function "RESUME".

42 Active signal to the lamp warning of braking. on lamp signal interrupts the cruise control system and prevents the installation of a constant engine speed for PTO.

Active signal 43 from the brake pedal sensor. The signal from the sensor interrupts the cruise control system and prevents the installation of a constant engine speed for PTO.

44 Switch idling accelerator pedal is active (accelerator pedal fully depressed).

45 Contact open clutch pedal (clutch pedal is partially or fully pressed). The signal from the clutch pedal interrupts the cruise control on and off manually set a constant engine speed.

46 The signal from the parking brake activated. The signal is a condition for the possibility to set manually a constant engine speed for PTO.

47 The safety signal is active. With active safety signal, the engine does not respond, the motor force goes into idle mode at a speed of 0 km / h, or the engine is switched off (depending on the security modes programmed into the engine control unit).

51 Cruise control is switched on. The signal from the cruise control switch is a condition for the cruise control and the possibility to install in ruchnuyupostoyannuyu motor speed for power take-off.

52 Active signal from the buttons "ON" and "SET" switch on the cruise control. When vehicle cruise control is activated. When the car stopped, activates the ability to install manually a constant engine speed for PTO.

53 Active signal from the buttons "ON" and "RESUME" on the cruise control switch. During the velocity renews the movement defined previously. When the car stopped, the engine speed increases or decreases to approximately 1000 rev / min.

61 ABS active signal. Engine Brake (VEB) does not function.

62 Communication with the control unit box Geartronic transmission. If no signal is Geartronic does not function.

63 Active VSP signal (engine control unit is in programming mode). The engine will not start.



Erasing the recorded DTCs.



1. Switch off the ignition for at least 10 seconds;

2. Press and hold the diagnostic button "Check Engine";

3. Turn the ignition switch;

4. Hold down the diagnostic button "Check Engine" approximately 3-4 seconds;

5. Release the button.

Registered codes in the memory of the engine control unit will be erased and will not appear before the failure.
