What Does C1507 Mean?
The traction control system's brake-based intervention has exceeded its maximum allowable operating time. The system applies individual wheel brakes to limit wheel spin, but prolonged activation can overheat brake components and cause damage. This code indicates the traction control braked one or more wheels continuously for longer than the designed safety limit, so it shut itself off. The driver likely experienced sustained wheel spin on a slippery surface, and the traction control light will flash or remain on.
Common Causes
35%
Sustained driving on extremely slippery surfaces (ice, mud, deep snow) causing continuous traction control activation
25%
Mismatched tire sizes or types causing constant wheel speed differences interpreted as wheel spin
20%
Faulty wheel speed sensor providing an incorrect speed reading that triggers continuous traction intervention
15%
ABS/traction control hydraulic modulator valve sticking in the apply position
5%
Traction control module calibration or threshold error
Diagnostic Steps
1
Review freeze frame data for this code — check which wheel(s) triggered the traction intervention and whether the wheel speed difference was legitimate or caused by a sensor error.
2
Inspect all four tires for matching size, tread depth, and type. Even small differences in rolling diameter can cause the traction control to see phantom wheel spin. Measure tread depth with a gauge at multiple points.
3
Check all four wheel speed sensor signals with the scan tool while driving — all sensors should read within 1-2 mph of each other during straight-line driving on smooth pavement.
4
If a specific wheel speed sensor shows erratic readings, inspect the sensor air gap, tone ring for damage or debris, and wiring for chafing.
5
Clear the code and test drive under normal conditions. If the code returns without extreme driving conditions, a sensor or modulator valve issue is likely. If it only occurs on very slippery surfaces, it may be a normal protective response.

The most common cause of C1507 (Traction Control of Brake Exceeds Time-Out) is: Sustained driving on extremely slippery surfaces (ice, mud, deep snow) causing continuous traction control activation
Typical repair costs for C1507 range from $0 to $600, depending on the vehicle, location, and whether you do it yourself or go to a shop.
The traction control system has temporarily disabled itself to prevent brake overheating. Normal braking and ABS functionality should still work. If this occurred during extreme driving conditions (deep mud, ice), it may be normal operation. If it occurs during normal driving, a wheel speed sensor or tire mismatch needs to be addressed. The vehicle is safe to drive but traction control may not be available until the system resets.
Start by connecting an OBD2 scanner to read the code and any freeze frame data. Then follow the diagnostic steps specific to C1507 to identify the root cause.
