No Bus Error

Buongiorno da Miami,

La tua Jeep funziona normalmente oltre all'accensione della spia? Il mio 05 LJ fa lo stesso e devo ancora trovare una soluzione alternativa oltre a rimuovere la lampadina. ho provato diversi pcms, software diversi e la luce rimane. Ho una chiave nera tra l'altro.

PS Ho fatto una foto in cima all'Etna (Fuoco dell'Etna) nel 2007. Amo il tuo paese.

Wow! Th

The A2 pin in the C1 connector to the PCM gets power from fuse 12 in the fuse block behind the glove box. That fuse gets power from the ignition switch when the key is in both the start & run positions. And that wire to the PCM splices & also goes to the ASD & fuel pump relay coils. The PCM also needs to ground the relay coil outputs to close those relays.

Check for power getting to fuse 12 & be sure the fuse is good & getting power out. If that is all good then you will have to start tracing that wire from the fuse block to the PDC (fuse/relay box in front of the battery). The splice is near the PDC & you know the wire from the relay in the PDC to the PCM is good since backfeeding from the relay did power up the PCM. It is known that corrosion at splices & terminal ends can cause issues like broken wires so if the wiring is suspect start at the back of the fuse block where the fuse terminals crimp to the wires then at the splice near the PDC.

Thank you for this helpful info. My Jeep just threw this code. I will check out all of the above. Thank you
