Code U0174 Jeep Description
The U0174 diagnostic trouble code (DTC) for Jeep vehicles indicates that there has been a loss of communication with the Left Side Satellite Acceleration Sensor 3. This sensor is responsible for detecting lateral acceleration on the left side of the vehicle and relaying this information to the vehicle's electronic control module (ECM). When communication with this sensor is lost, it can have significant implications for the vehicle's performance and safety systems.
Common Causes of U0174 Jeep
- Faulty Left Side Satellite Acceleration Sensor 3.
- Damaged wiring or connectors leading to the sensor.
- Corrosion or moisture intrusion in the sensor or its connections.
- ECM software issues affecting communication with the sensor.
- Physical damage to the sensor due to impacts or improper handling.
Symptoms of U0174 Jeep
- Illumination of the stability control or traction control warning light on the dashboard.
- Increased difficulty in maintaining control of the vehicle during sharp turns or sudden maneuvers.
- ABS system malfunctions, such as pulsating brakes or extended stopping distances.
- Decreased overall stability and handling of the vehicle, especially on slippery road surfaces.
How to Fix U0174 Jeep
- Begin by conducting a thorough visual inspection of the wiring and connectors leading to the Left Side Satellite Acceleration Sensor 3. Repair or replace any damaged or corroded components.
- Test the sensor itself using a multimeter to ensure it is functioning correctly. Replace the sensor if it is found to be faulty.
- Clear the DTC from the vehicle's ECM using a diagnostic scan tool.
- Test drive the vehicle to verify that the stability control system is functioning properly and that the U0174 code does not return.
- If the code persists, further diagnostics may be necessary to identify any underlying issues with the ECM or other related components.
Cost to Fix U0174 Jeep
The typical repair costs for addressing a U0174 code on a Jeep vehicle can vary depending on the specific cause of the issue and the labor rates at the auto repair shop.

Precautions for SRS “AIR BAG” and “SEAT BELT PRE-TENSIONER” Service
- Never probe the electrical connectors on air bag, side air curtain modules or seat belts.
- Never disassemble or tamper with safety belt buckle/retractor pretensioners, adaptive load limiting retractors, safety belt inflators, or probe the electrical connectors.
- Do not use electrical test equipment to check SRS circuits unless instructed to in this Service Manual.
- Before servicing the SRS, turn ignition switch OFF, disconnect both battery cables and wait at least 3 minutes. For approximately 3 minutes after the cables are removed, it is still possible for the air bag and seat belt pre-tensioner to deploy. Therefore, do not work on any SRS connectors or wires until at least 3 minutes have passed.
Failure to follow this instruction may result in the accidental deployment of these modules, which increases the risk of serious personal injury or death.
