What Does U0415 Mean?
The ABS control module is sending corrupted or illogical data over the vehicle's communication network. Other modules receiving this invalid information cannot properly coordinate braking and stability functions.
Safety Warning
ABS, traction control, and stability control may be disabled or function erratically, significantly increasing accident risk especially in emergency braking or slippery conditions. Vehicle should not be driven until repaired.
Common Causes
35%
Faulty ABS control module with internal corruption or component failure
30%
Corroded or damaged CAN bus wiring between ABS module and other control modules
15%
Low vehicle battery voltage causing module communication errors
12%
Software glitch or outdated calibration in ABS module requiring reprogramming
8%
Water intrusion or physical damage to ABS module housing
Diagnostic Steps
1
Step 1: Check battery voltage with engine running; should be 13.5-14.5V to ensure stable module operation
2
Step 2: Inspect ABS module connectors for corrosion, bent pins, or moisture intrusion
3
Step 3: Use scan tool to monitor live data from ABS module while operating vehicle to identify corrupted parameters
4
Step 4: Check CAN bus voltage and resistance between ABS module and other control modules using multimeter
5
Step 5: Attempt ABS module software update/reflash if available; replace module if data remains invalid
Estimated Repair Cost
$200 - $1,500
Parts + labor, varies by vehicle and location
The ABS control module is sending corrupted or illogical data over the vehicle's communication network. Other modules receiving this invalid information cannot properly coordinate braking and stability functions.
The most common cause of U0415 (Invalid Data Received From Anti-Lock Brake System Control Module) is: Faulty ABS control module with internal corruption or component failure
Typical repair costs for U0415 range from $200 to $1,500, depending on the vehicle, location, and whether you do it yourself or go to a shop.
ABS, traction control, and stability control may be disabled or function erratically, significantly increasing accident risk especially in emergency braking or slippery conditions. Vehicle should not be driven until repaired.
