VALTRA Tractor Fault Codes DTC
If the display unit shows a fault code:
Measures:
VALTRA Tractor Fault Codes DTC
- Decode the fault code according to instr. 370/5 —6 (self —diagnosis)
- Check the function of the component in the test modet (instr. 370/8).
- Repair the fault.
- If the control unit A1A or programs have been changed, make necessary settings according to instr.
370/24A. - Carry out all points in the test mode (instr. 370/8). This ensures, that the tractor is OK before delivery.
From ser. no.
K41107 — incl: Check in the fault code memory F1. - Test — run the tractor according to instr. 370/24E.
— If the display does not show the fault code:
In the table below, there are faults which have not the fault codes:
Component: Possible reason: Measures: - AC 5 display unit does not function (on the LH side pillar)
— control unit A1 supply voltage or earth has malfunctions or the display supply.
— display unit P6 faulty
— control unit connector A1A1 loose
— check fuse F24
— voltage measures from control unit A1
connectors A1A1/1 – A1A1/2 (=battery voltage)
— new display unit, if the system does not function
— check connections - In the dashboard there is lit “P”, although the driving direction has been selected
— shuttle lever switch S15 (P) faulty or
wrongly fitted.
— testing in the test mode, point d16 / d22
— 1)
— check the fitting of switch S15 (page 370 —20) - Black arrow is blinking, although the driving direction has been selected
— driver has left the seat over 4 (6) seconds. AC 5.2: over 30 sec., when the clutch pedal is depressed.
— detector switch S60 (in the seat) does not function or wire damage
— on the seat, shuttle lever to position P, shuttle lever to the driving position
— testing in the test mode, point d05, 2) - Black arrow does not change, when using the shuttle lever
— shuttle lever switch S40 (F) or S41 (R) faulty or loosed in the frame.
— testing in the test mode, points d09, d10 / d18, d19 - Shuttle, DPS or PTO have malfunctons (e.g. function is slow) — fault, that the control unit A1 has not identified
— pressure in the low pressure circuit too low
— clutch pre —fillling or initial pressure indexes are wrongly set
— carry out all procedures in the test mode (instr. 370/8)
— low hydraulics pressure measuring, see instr no. 911 —1
— check indexes / in the setting mode,
(instr. 370/24D, AC5.2: instr. 371/11.) - Engine does not start (starter motor does not rotate) Tractors J38343 —.
— no supply to control unit A1.
— Parking brake switch S15 or input signal A1A4/14 (AC 5) or A1A8/8 (AC 5.2) faulty
— Control unit output signal A1A2/3 (AC
5) (to relay K28) or A1A3/5 (AC 5.2) faulty.
— check fuse F24
— testing in test mode, point d16/d22 (if necessary, change switch or control unit)
— Check whether the voltage from control unit A1 is in relay K28 (when necessary, change the control unit).
