These fault codes lists and DTCs are applicable for the engine DCi 11 of Renault Kerax and Premium
Diagnostics using blink codes (dCi 11 B43)
The blink code procedure allows only present faults to be visualized. (The RENAULT TRUCKS diagnostics tool serves to visualize present faults and memorized faults).
Activation of the procedure
On the cruise control stalk switch:
- Move ring (1) to “OFF”.
- Turn ring (2) to bring “R+” or “S-” opposite the mark and hold it there, until the light goes out.
The test lights (3 – 4) signal present faults by means of an easy-to-decipher code.
The fault code number is defined by two series of short flashes separated by the light going out for 5 seconds.
By counting the flashes in each series, two numbers can be formed:
The two numbers correspond to a fault code number. Each fault has a precise meaning.
After displaying the fault code number, the test lights go out and come on again as long as the fault persists.
Other faults may exist. Turn the ring (2) again to bring “R+”
or “S–” opposite the mark for each other present fault.
Interpretation of fault code numbers
After activating the procedure:
- The test light emits a series of flashes.
- The test light stays off for 5 seconds.
- The test light emits a new series of flashes.
- The test light stays off for 5 seconds.
- The display cycle is repeated continuously
By counting the flashes in each set, a two-figure combination is obtained:
- The first series of flashes represents tens.
- The second series of flashes represents units.
Erasure of fault code numbers
Only the RENAULT TRUCKS diagnostic tool DIAGNOSTICA allows memorized faults to be erased.
