Getting a "PS Trouble 514,530 013" error code. The power steering has stopped working. Had no problems with the PS one day, the following it didn't work.

The first fault code we will discuss is the 013. This telling you that there is Trouble in the Power Steering. The 514 code is saying to that the Power Steering IGBT transistor and the current sensor need to be checked, The 530 fault is telling you that the vehicle's electrical system has a short in it. More then likely the steer motor seen it's better days, more then likely the factory smoke has escaped and ran away, when this happened it took the steering transistors with and may have overloaded the current sensor. There is even a strong possiblity that it took the control transistor on the main control print board out. You could be looking at some ugly amount of parts cost alone. When last I checked the IGBT transistors (pair) cost abt 980.00 USD, Steer motor new 1,000.00 USD and the main board abt. rebuilt 11,000.00 USD. You can hold your cost down by rebuilding the motor at abt. 250.00 USD, the Main board, depending on who does the repair could come in at less then 500.00 USD. Now comes the bad news Transistor are throw away with no value. These transistors have been upgrade from 75 Amp to 100 Amp capacity. I hope this is what you were wanting to know.
Best To You;

Wow! That's a lot of great information and cost! Do you also know the part numbers for the IGBT and main board? I guess I need to start calling around to get some pricing. We have had this truck for about 3yrs and put on less the 500hrs.  After just replacing the battery a few months ago, we have almost as much into this as what we paid for it. Very disappointing.

Send Print board to Flight Systems -Mechanicsburg, PA. and see what they say.  There are quanity of 12 different print boards that could be.  Which one of the 12 is known thru research and/or crossing over the Hitachi No. to a Nissan P/N.

You have a truck that came off the assembly line after Dec 97. The error codes appearing on the display are saying you have a short circuit condition in the traction drives power circuit. Check to see that the truck's chassis is electrically clean. Do this by removing the battery from the truck and having it connected to the truck while outside of the truck. With the drive wheels raised off the floor, battery as described, push buttons 1 & 4 down and turn key switch ON press button 1. Wait till all switches have stopped clicking note any and all error number that appear, also if an asterisk mark precedes the number code. Is this truck equipped with speed controlled hydraulics. Push button 3 will take you to window 500 (lower right corner) button 1 error memory screen 610 .

The * mark ahead of the fault code number is present to inform you that the truck in question has multiple malfunctions occurring. 514/530 fault codes are saying that there is a short in the power steering power circuit. Look for an armature  short in the power assist motor. The 526 error is a PS current sensor that has an elec. open. 510 is the self dianostic check window.

Hello everybody!

I have a NISSAN P02 truck (model QP02L20U). When the trucks is ON, automatically appears on display "PS TROUBLE 013". The PS contactor is not actuated, and the electric steer is not working. I did some verifications:

1) On the back, I disconnect the steer motor cables, and tested  the steer motor with 30V conecting. The motor worked ok, without problem to the booth sides.
2) Check the potenciometer (steer sensor) cables on back. I disconnected the CN2 plug on the main controller, and then tested the poti values. Are ok!
3) I checked the PS contactor coil resistance value, aprox 260 OHMs, is ok. The cables are ok.
4) IGBTs power transistors are ok, and the connections wires (CN1) for to control them are ok too.
5) I conected the truck ON, and at the same time I pressed manually the contacts of the PS contactor. Nothing happened. There is not a short circuit on the power circuit, because when I closed the PS contactor´s contacts nothing happend.

please help me!
best regards

Hi Mate

If all those checks are ok I guess it points to the main pcb.  As this also feeds the power steer circuit.

You need to perform interactive dianostics of the truck's control to define the power assist steering issue. The way to do this is to push FN 1 and FN 4 in while you simultaneously turn on the key switch. You will see the self check menu in the display screen. The power contactors in the power distribution panel will all close and open in an orderly sequence. Push the FN 3 Diagnostic check window 500 should now appear. Now push FN 1  Error Memory  window 510 will appear. Malfunctions which have occurred in the traction, loading, and power steering systems are recorded.

Hey now, I'm also getting the 514 followed by a 526 amd a 524, was wondering if anyone had a definition for the 524 in particular. Thanks in advance.

The 524 is a traction control current sensor issue, while the 514 can be a short or open transistor issue with the power steering, depending as to if there is a 531 or 530 code also. Now the 526 fault could either be a power steering open in the large resistor or the small resistor which could be better defined if there occurred a 530 or a 531 fault also.

Thank you much for your response, the information is appreciated. That is an odd mix of codes. The only two that seem to correlate are the 514 and 526. I don't believe there was a 530 or 531 but l will make sure to run the diagnostic system again on Monday morning.
