Why the Dodge DTC U1113 Code Matters in December

If you’re a collision repair shop, used car dealer, or salvage title vehicle owner in Lewisville, TX, the diagnostic trouble code (DTC) U1113 isn’t just a random string—it could be a warning sign that your Dodge’s air suspension system or safety electronics are malfunctioning. With colder weather in December and the holiday season increasing road time, ensuring your vehicle’s safety systems are fully functional is more important than ever.

What Does DTC U1113 Mean on a Dodge?

The U1113 code specifically refers to a “Sensor Supply 1 Voltage Circuit Short to Ground.” In plain language, this means the air suspension control module (ASCM) has detected a short circuit in the 5V sensor supply—typically affecting components like the ride height sensors. When this 5V reference signal shorts to ground, it disrupts data communication between vehicle modules and could impair suspension performance or even safety systems.

Common Causes of U1113 in Dodge Vehicles

This code may be triggered by several issues, including:

  • A damaged 5V reference wire shorting to ground
  • Faulty ride height sensors (especially rear-left or rear-right)
  • A defective Air Suspension Control Module (ASCM)
  • Water intrusion or corrosion in connectors or wiring
  • Faulty or miscalibrated related sensors

In vehicles that have been in accidents, especially rebuilt or salvage title cars, damaged wiring harnesses are a frequent culprit.

Symptoms You Might Notice

Whether you’re a body shop prepping a vehicle for resale or a used car owner noticing unusual behavior, the signs of trouble could include:

  • Suspension warning lights on the dashboard
  • Vehicle sitting unevenly or sagging on one side
  • Poor ride comfort or handling
  • Air suspension not adjusting correctly
  • Airbag warning light illuminated (if the fault impacts other control modules)
