What Does C1415 Mean?
The ABS/traction control module has detected that its configuration parameters do not match the vehicle's actual hardware setup. This can include mismatches in wheel size, axle ratio, drivetrain type (AWD vs FWD), or installed option content. The module may disable some or all functions because it cannot accurately control systems with incorrect parameters.
Safety Warning
ABS and traction control systems may be disabled or operating with wrong parameters, which could cause incorrect or dangerous brake intervention behavior. Do not rely on ABS or stability systems until the module is properly configured. Drive cautiously and have this addressed immediately.
Common Causes
40%
ABS module not properly configured after replacement or reprogramming
25%
Vehicle configuration data lost or corrupted in module memory
20%
Module transplanted from a differently-equipped vehicle of the same model
15%
Aftermarket wheel/tire size change without module reconfiguration
Diagnostic Steps
1
Read the module configuration data using the manufacturer's diagnostic tool. Compare the stored configuration (drivetrain type, wheel size, axle ratio, option codes) against the vehicle's actual build sheet or door jamb sticker.
2
If configuration parameters are incorrect, use the manufacturer's module configuration/setup procedure to reprogram the correct vehicle parameters into the module.
3
Check if the vehicle has had aftermarket wheel/tire size changes. Some ABS modules require reconfiguration when wheel speed sensor pulse rates change due to different tire circumferences.
4
If the module was recently replaced, ensure the complete post-installation setup procedure was performed, including VIN programming, vehicle configuration, and any required sensor calibrations.
5
After reconfiguration, clear all codes, perform a steering angle sensor calibration if equipped, and road test to verify ABS and traction control function correctly.

The most common cause of C1415 (Incorrect Module Configuration) is: ABS module not properly configured after replacement or reprogramming
Typical repair costs for C1415 range from $150 to $800, depending on the vehicle, location, and whether you do it yourself or go to a shop.
ABS and traction control systems may be disabled or operating with wrong parameters, which could cause incorrect or dangerous brake intervention behavior. Do not rely on ABS or stability systems until the module is properly configured. Drive cautiously and have this addressed immediately.
Start by connecting an OBD2 scanner to read the code and any freeze frame data. Then follow the diagnostic steps specific to C1415 to identify the root cause.
