Code C2104 Chrysler Description

The C2104 Chrysler code indicates a problem with the ABS/ESC valve supply voltage circuit being open. This means that the Anti-lock Brake System (ABS) and Electronic Stability Control (ESC) systems may not be receiving the necessary voltage to function properly. This can result in decreased braking performance, loss of traction control, and compromised vehicle stability during braking and cornering. The ABS/ESC systems rely on sensors and control modules to monitor wheel speeds and make adjustments to optimize braking and stability. If the supply voltage circuit is open, it can disrupt the communication and operation of these systems, potentially leading to unsafe driving conditions.
