The reference covers 296 codes from the factory tables of Renault Trucks — the full list by system is below, stop-now codes first.
Renault Trucks in the free tables: 296 codes under J1939, one of the fuller SPN tables on the site. The most common areas are fuel, brakes and the power supply. Brake codes are listed separately, and if ABS codes are in the reading, start with the brakes rather than the engine. Renault has 91 codes in the dealer format, mostly with letter codes such as IND103.
Start with these codes:
A code has two halves. SPN is what is actually at fault — the sensor, component, or parameter. FMI is what is wrong with it — value out of range, open circuit, short circuit, invalid data. So “SPN 100” alone is not a diagnosis yet, but “100/1” already tells you oil pressure has dropped below normal.
That is almost always how it goes: one fault drags five or six codes behind it. An empty AdBlue tank first throws a level error, then interrupted dosing, then a NOx excess and a torque derate. Fix the root cause and the rest clear on their own. Paste the whole list — we will show which code is the root cause.
| IND103 | Battery, open circuit: at the alternator charging input the instrument system did not detect the alternator |
| SPN16 | Winding relay 1, short to positive or open circuit |
| SPN22 | Winding relay 3, short to ground |
| SPN33 | Lever in position 1, short to positive |
| SPN39 | Lever in position 1, short to ground |
| SPN45 | Lever in position 2, open circuit |
| SPN53 | Control unit internal fault (flash memory) |
| SPN537 | Oil level sensor fault |
| SPN561 | EGR valve fault |
| SPN568 | Intake air preheater relay fault |
| SPN581 | Injector 2, cylinder 5 fault |
| SPN73 | CAN bus fault, open circuit |
| SPN805 | Sensor supply |
| SPN833 | Injector 1, cylinder 1 fault |
| SPN849 | Pump 1 solenoid valve, open circuit or short |
