ABS/ESP lights on and Cruise control works?
Couple of days ago ABS/ESP lights came on the dash. Checked the codes with Delphi and got a code C1310. Can’t remember correctly, but it had something to do with undervoltage. Cruise control still works.
Will STAR show more info? Any help is welcome.

Mercedes C-Class ABS pump and module failure will cause the ABS warning light to remain active. The most common fault code to be found when scanning the vehicle is C1310 – pump motor malfunction.

Hi ryan1g, I hope this will help. The C1310 code related to undervoltage in the ABS/ESP system could indicate several potential issues with the electrical system of your vehicle:
- Battery Condition: Often, a weak or failing battery can trigger undervoltage warnings in various vehicle systems, including the ABS/ESP. Ensure that your battery is in good condition, holding a charge, and is properly connected.
- Faulty Alternator: A malfunctioning alternator may not be providing sufficient power to recharge the battery or maintain voltage levels in the vehicle's electrical system. Have the alternator tested to ensure it's functioning correctly.
- Poor Electrical Connections: Loose or corroded connections, especially those related to the ABS/ESP system, can cause voltage irregularities. Check the connections to the ABS sensors, control modules, and related wiring for any signs of corrosion or damage.
- Faulty ABS Module: In some cases, the ABS control module might be malfunctioning, causing the undervoltage issue. Diagnosing this would typically require professional diagnostic tools to pinpoint the exact cause.
