In rare instances, the ECU (calculador) producing the information may have an internal software or hardware fault. Troubleshooting and Repair Steps

: The adaptive cruise control radar is typically located behind the front bumper. While the unit itself rarely fails, common issues include:

When the DF357 code is active, you're unlikely to notice a loss of engine power. Instead, the issues will be centered around the vehicle's electronic safety and assistance systems. Reported symptoms include:
