Safety Warning
DIY auto repair can cause serious injury, fire, or vehicle damage. These guides are for informational purposes only. Always follow OEM torque specs, wear PPE, and consult a certified mechanic if you are unsure. You are solely responsible for your safety.
AVC Module
| Refer to COMPONENT INDEX . |
The AVC module is mounted under the hood to the bulkhead on the driver side near the brake booster away from heat sources. The AVC module will operate the AVC actuators when the engine is in MDS operation mode as triggered by Controller Area Network - Chassis (CAN-C) message. The AVC module receives engine RPM as an input from CAN-C and a dedicated hard wired crank signal. The AVC module will adjust its output (frequency, phase, and amplitude) based upon the inputs. A software algorithm uses engine characteristics and vibration sensed by accelerometer to generate an output for actuators to produce the anti-vibrations.
CAN-C Inputs
- Commanded ignition switch status.
- Engine RPM.
- Vehicle Speed.
- Odometer.
- MDS active signal.
- Vehicle configuration data for wheelbase length.
- Vehicle drive configuration.
CAN-C Outputs
- AVC failure display request to the Instrument Panel Cluster (IPC).
Hardwire Inputs
- Crank pulse signal.
- Left AVC sensor signal.
- Right AVC sensor signal.
Hardwire Outputs
- Left AVC actuator operation.
- Right AVC actuator operation.
- Crank pulse signal to the ANC system.

When to See a Mechanic
Stop DIY work and contact a certified mechanic immediately if any of the following apply:
- • You smell fuel, burning insulation, or see smoke.
- • Brakes feel soft, pull hard to one side, or make grinding noises.
- • The engine overheats, stalls repeatedly, or misfires under load.
- • You are missing required tools, torque specs, or safe lifting equipment.
- • You are not confident in the next step or safety outcome.
