OBD-II DTC C1248 – ABS Outlet Valve Coil RR Circuit Short To Battery

DTC C1248 meaning

DTC C1248 refers to a diagnostic trouble code indicating a short circuit in the ABS outlet valve coil for the right rear wheel. This code is part of the On-Board Diagnostics II (OBD-II) system, which monitors various components of the vehicle’s anti-lock braking system (ABS). A short to battery means that the electrical circuit is receiving an unintended voltage, which can lead to improper functioning of the ABS system.

Common symptoms associated with DTC C1248 may include:

• Illumination of the ABS warning light on the dashboard
• Loss of ABS functionality
• Increased stopping distances during braking
• Unusual noises from the ABS module
• Potential activation of the traction control system warning light

Several factors can lead to the occurrence of DTC C1248, including:

• Damaged or frayed wiring in the ABS outlet valve circuit
• Faulty ABS outlet valve coil
• Corrosion or poor connections in the electrical circuit
• Short circuit due to moisture or debris in the connector
• Malfunctioning ABS control module

DTC C1248 seriousness

DTC C1248 is considered a serious issue as it directly affects the vehicle’s braking system. The ABS is crucial for maintaining control during emergency braking situations. If left unaddressed, this code can lead to:
