B0502 und B0507 kommen wohl weil Deine Tagfahrlicht Relais gezogen wurden....
Ist nicht weiter schlimm - kannst Du ignorieren oder wieder auf US zurückrüsten.
DTC P0430 sagt zunächst einmal aus das Dein betreffender Kat nicht mehr effektiv arbeitet.
Das PCM untersucht ständig die Effektivität des Kats.....
The PCM performs this diagnostic during idle. When the conditions for running this DTC are met, the following conditions occurs:
The PCM captures the current rear HO2S rich-to-lean status.
The air-to-fuel ratio transitions from rich to lean or from lean to rich, depending on the capture rear HO2S rich-to-lean status.
The air-to-fuel ratio transitions a second time opposite the first air-to-fuel ratio transition.
The PCM captures the response time of the front and rear heated oxygen sensors when the air-to-fuel ratio transitions occur. The HO2S response time goes from less 300 mV to more than 600 mV, and from more than 600 mV to less than 300 mV.
The PCM measures the time it takes the rear HO2S voltage to cross a reference rich-to-lean threshold, minus the time it takes the front HO2S voltage to cross the same rich-to-lean threshold. The difference between the front HO2S time and the rear HO2S time is the oxygen storage capacity of the catalyst. This DTC sets if the time exceeds a predetermined threshold.
