U0415 on Jeep: How to Diagnose & Fix
Invalid Data Received From Anti-Lock Brake System (ABS) Control Module

U0415 on Jeep by model: symptoms, diagnosis and fix
Quadra-Lift is a closed, electronically controlled air-suspension system, so a Service Air Suspension message, a low corner, or a denied height change does not identify one universal failed part. The factory diagnostic path covers electrical and communication faults, fuses and voltage, pinched or damaged lines, leaking springs, disconnected sensor linkages, water or blockage in the compressor intake, air-mass loss, valve/compressor faults, software, and the Air Suspension Control Module. The prior card also incorrectly treated SRT and Trackhawk as automatic Quadra-Lift applications; applicability should be established by sales code SER or the vehicle build sheet.
Common Symptoms
- Service Air Suspension message
- One corner or one axle sits low
- Ride-height change is slow, denied, or inoperative
- Quadra-Lift height indicators flash or normal leveling is disabled
How to Fix
Confirm the vehicle is equipped with Quadra-Lift sales code SER, record the exact ASCM DTCs and environmental data, and check VIN/build-date-specific FCA bulletins before ordering hardware. Follow the factory sequence: repair voltage or communication faults first; inspect fuses, air lines, springs, height-sensor linkages, compressor intake/filter, and visible plumbing; then use a capable scan tool to run the Air Mass and Air Ride Height routines and follow the DTC-specific tree. On 2011-2012 vehicles built before May 1, 2012, U0415-00 or C159E-15 with a Service Air Suspension message may be addressed by FCA TSB 08-034-12's ASCM software update. Replace only the component proven failed. A completely depleted system requires the specified refill equipment, scan-tool procedure, and purity-class-5 nitrogen; do not fill it with ordinary shop air or shotgun-replace springs, sensors, and the compressor.
Owner tips & cautions
- WarningDo not replace a compressor because the vehicle sits low. A leaking spring or line, sensor/linkage fault, intake restriction, valve fault, low system air mass, or software condition can create overlapping symptoms and can overwork a replacement compressor.
- TipAsk the shop to record the ASCM DTCs, air-mass result, ride-height routine result, and verified leak location. Those findings should select the part, not a generic model-level shopping list.

Frequently asked questions
What does U0415 mean on a Jeep?
U0415 stands for "Invalid Data Received From Anti-Lock Brake System (ABS) Control Module." Sets when a receiving module gets invalid or implausible data from the ABS Control Module over the bus. Because stability/traction systems rely on this data, it is treated as safety-critical. On Jeep it is documented across 1 model: Grand Cherokee.
What are the most common causes of U0415?
The most common causes of U0415 are: CAN bus wiring fault or poor ground, Weak battery / low voltage, Faulty ABS module or wheel speed sensor data, Connector corrosion, Software/calibration mismatch. The specific cause varies by vehicle.
How much does it cost to fix U0415 on a Jeep?
Repair costs vary widely with the root cause and Jeep model; each issue on this page carries its own estimate where one is published.
