C1AC2 2014 Toyota RAV4 Code - Slave Module Horizontal Axis Misalignment

The code C1AC2 indicates "Slave Module Horizontal Axis Misalignment," meaning the vehicle's parking assist system detects an alignment issue with the slave module.

Symptoms may include malfunctioning parking assist sensors, inaccurate distance measurements, or a warning light on the dashboard for the parking assist system.

Common causes include improper installation of the slave module, physical damage to the module, or environmental factors such as debris or dirt obstructing its operation.

While primarily affecting the parking assist system, it may also impact the vehicle's overall safety features if the misalignment prevents accurate obstacle detection.

A mechanic will use an OBDII scanner to read the code and inspect the slave module for alignment issues, damage, or obstructions.

If the issue is minor, such as cleaning dirt or debris from the module, you may be able to fix it yourself. More complex issues like physical damage or misalignment typically require professional assistance.

Yes, but the parking assist system may not function properly, making it harder to detect obstacles and increasing the risk of minor collisions when parking.

Repair costs can vary depending on the issue but typically range from $100 to $300 for diagnostics and module realignment. Replacement costs may be higher.

Resetting the code without addressing the underlying issue will not fix the problem, and the code is likely to return.

Regularly clean the parking assist sensors and ensure the modules are properly aligned during maintenance or after repairs.
