Disconnect the suspected BCM. Does the resistance on the OBD2 port change to 120 ohms? If yes, the BCM was shorting the bus. If no, the problem is elsewhere (wiring or other modules).
The CAN bus wires are a twisted pair (usually CAN High and CAN Low). If these wires short together, short to ground, or break due to chafing against metal brackets, the module at 0x08 will drop offline. Common chafe points include the A-pillar area and behind the glovebox. fiat 0x08
Fiat 0x08 is both emblem and cipher: a compact signifier that merges the antiquity of monetary certainty with the abstraction of machine-readable truth. This treatise treats it not as a mere token but as a lens through which to examine value, code, trust, and the cultural rituals that bind them. Disconnect the suspected BCM
Unlike a misfire or oxygen sensor code, 0x08 is rarely a component failure. It is a communication failure. Here are the four most common reasons this code appears. The CAN bus wires are a twisted pair
