Manufacturer summary

Original wording in English

"Base led headlamp RT 25 MY HDCC Ignition DTC (U300A-29 Ignition Switch - Signal Invalid) in stored state for SLML and SLMR. All headlamps on the Heavy Duty with SW 24.43.00(Premium) or 24.44.00(Base) will show a U300A-29 -> Ignition Switch-Signal Invalid as a stored DTC. If you experience this condition, please clear the DTCs on SLML and SLMR once and restart the truck and check if the DTC is in active state 10 seconds after the engine is turned ON, check the hardware ignition line and repair as required. If the DTC reappears as stored DTC (See Figure 1), no repair is required. The headlamps are good. The DTCs will appear every time the Ignition is cycled, and should be ignored."

Repeated filings are grouped only when make, bulletin number, publication date and complete summary agree. Original record numbers are retained. Older publications remain available, and an explicit later version is shown when established. Pre-1994 vehicle associations are separated from default results; an unspecified year does not mean all model years apply.
