C1216 – OBD-II DTC

OBD-II DTC C1216 – ABS Inlet Valve Coil RF Circuit Short To Battery

DTC C1216 meaning

DTC C1216 refers to a diagnostic trouble code related to the Anti-lock Braking System (ABS). Specifically, it indicates a short circuit in the inlet valve coil for the right front wheel. This short circuit is detected when the ABS control module identifies that the electrical resistance in the circuit is too low, suggesting that the coil is receiving an excessive voltage, potentially leading to malfunctioning of the ABS system.

DTC C1216 symptoms

Common symptoms associated with DTC C1216 may include:

• Illumination of the ABS warning light on the dashboard
• Loss of ABS functionality, leading to potential wheel lock-up during hard braking
• Increased stopping distances
• Unusual noises from the ABS module or valves

DTC C1216 causes

Several factors can lead to the occurrence of DTC C1216, including:

• Faulty inlet valve coil for the right front wheel
• Wiring issues, such as frayed or damaged wires in the ABS circuit
• Corrosion or poor connections at the ABS module or valve connectors
• Defective ABS control module

DTC C1216 seriousness

DTC C1216 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:

• Increased risk of accidents due to reduced braking efficiency
• Potential damage to other components of the braking system
• Failure of the vehicle to pass safety inspections

How to diagnose DTC C1216

To diagnose DTC C1216, follow these steps:

1. Use an OBD-II scanner to confirm the presence of the C1216 code.
2. Inspect the wiring and connectors associated with the right front inlet valve coil for any visible damage or corrosion.
3. Test the resistance of the inlet valve coil using a multimeter to ensure it is within the manufacturer’s specifications.
4. Check the ABS control module for any additional codes that may provide further insight into the issue.
5. Perform a continuity test on the wiring harness to ensure there are no breaks or shorts.

How to fix DTC C1216 step-by-step instructions

To fix DTC C1216, follow these step-by-step instructions:

1. Disconnect the vehicle’s battery to ensure safety while working on the electrical system.
2. Inspect and repair any damaged wiring or connectors related to the right front inlet valve coil.
3. If the inlet valve coil is faulty, replace it with a new component that meets OEM specifications.
4. Reconnect all connectors and wiring, ensuring they are secure and free of corrosion.
5. Reconnect the vehicle’s battery.
6. Clear the DTC using an OBD-II scanner and perform a test drive to verify that the ABS system is functioning correctly.

How to erase DTC C1216

To erase DTC C1216, follow these steps:

1. Connect an OBD-II scanner to the vehicle’s diagnostic port.
2. Turn on the ignition without starting the engine.
3. Navigate to the “Erase Codes” or “Clear DTCs” option on the scanner.
4. Confirm the action to clear the trouble codes.
5. Disconnect the scanner and start the vehicle to ensure the code does not reappear.
