C1507 — Traction Control of Brake Exceeds Time-Out

OBD2 code C1507 flags a problem with the ABS / stability control (traction control of brake exceeds time-out). Short, gentle driving to a shop is usually possible. Common culprits: damaged sensor wiring or corroded connector, blown fuse or low voltage to the ABS module, damaged tone (reluctor) ring on the hub.

Is it safe to drive?

Drive with caution The base brakes usually still work, so careful driving is possible — but ABS and stability control are disabled, which lengthens stopping distances on slippery roads. Fix promptly and avoid harsh driving.

How to diagnose with an OBD scanner

Read the code and freeze frame Connect an OBD2 scanner, confirm C1507 is stored, and save the freeze frame data — it shows engine conditions when the fault was detected.
Check for companion codes and TSBs Related codes often reveal the real root cause. Also check manufacturer technical service bulletins (TSB) for your make and model — many C0xxx issues have factory fixes or software updates. Search by VIN on the manufacturer site or nhtsa.gov.
Inspect wiring and connectors Visually inspect the wiring harness and connectors related to the ABS / stability control for damage, corrosion, chafing or poor contact.
Subsystem check Read all four wheel speed PIDs while driving slowly — the faulty sensor drops out or reads implausibly.
Subsystem check Inspect the sensor and tone ring for metal debris and damage near the hub.
Verify the repair Clear the code, complete a full drive cycle including the conditions from the freeze frame, and confirm C1507 does not return.

Approximate repair cost

Repair cost depends on which component actually failed. Typical scenarios for C1507 (parts and labor, USD, independent shop rates): ABS module repair or replacement: $400–$1,200; Repair sensor wiring: $80–$250; Replace a wheel speed sensor: $120–$350. Overall, fixing C1507 usually costs between $80 and $1,200. An accurate diagnosis before buying parts saves money — the most expensive scenario is rarely the first one to check.

Common questions

What are the symptoms of C1507?

Drivers most often notice: ABS or ESC warning light on, stability control disabled message, brake pedal pulsation changes, speedometer or cruise control issues.

Will C1507 clear itself?

Sometimes C1507 clears after a few drive cycles if the fault was intermittent — for example a loose connector or a tank of bad fuel. The underlying cause usually remains, so the code tends to return. Clear it once; if it comes back, diagnose rather than erase it repeatedly.

What is the most common cause of C1507?

The most common causes are: damaged sensor wiring or corroded connector, blown fuse or low voltage to the ABS module, damaged tone (reluctor) ring on the hub.

How do I diagnose C1507 myself?

Start with a scan: confirm C1507, save the freeze frame and note any companion codes. Then inspect the wiring and connectors related to the ABS / stability control, and verify the suspect component against live data before buying parts.

What does OBD2 code C1507 mean?

When the powertrain control module logs code C1507, it is flagging a specific problem within the antilock brake and electronic stability systems. This particular fault indicates that the traction control function tied to the brake system has exceeded its expected response window — essentially, the component did not react within the timeframe the computer anticipated. The chassis control unit stores C1507 in its memory only after running multiple verification checks, which prevents false alarms triggered by temporary electrical glitches.

The module responsible for C1507 continuously watches over the wheel speed sensors, the ABS pump, and the stability control valves while the vehicle is in motion. When sensor readings fall outside programmed parameters for longer than allowed, or when a signal drops out entirely, the computer interprets this as a traction control failure. It records freeze frame data alongside the fault code, capturing real-time engine RPM, vehicle speed, load values, and coolant temperature at the exact moment the malfunction occurred. That snapshot becomes the roadmap for anyone attempting to diagnose the root cause.

Setting C1507 is not a judgment call — it is a binary response to measurable conditions. The ECU has confirmed the abnormality across successive drive cycles, which is why simply clearing the code and hoping for the best rarely works. The underlying issue must be identified and resolved, or the light will return and the safety systems will remain compromised.

Common Symptoms of C1507

The ABS or electronic stability control warning lamp illuminates on the instrument cluster
A message appears indicating that stability control has been disabled or is unavailable
The brake pedal feel changes, sometimes accompanied by unexpected pulsation during normal braking
The speedometer behaves erratically or cruise control refuses to engage
The antilock system fails to activate during hard braking maneuvers, leaving standard disc brakes to handle the stop alone

What Causes C1507?

The most frequent culprits behind C1507 are the wheel speed sensors and their associated hardware. These sensors feed critical data to the ABS module, and any interruption in that signal chain triggers time-out conditions.

A damaged or worn wheel speed sensor
Corroded or loose electrical connectors at the sensor or ABS module
Physical damage to the tone ring (reluctor ring) mounted on the wheel hub
Insufficient voltage reaching the ABS module, often due to a blown fuse
A malfunctioning ABS control module or pump motor assembly

How to Diagnose C1507

Targeted diagnosis prevents unnecessary part swapping and keeps repair costs reasonable. Follow this sequence to isolate the fault efficiently.

Plug in a compatible OBD2 scanner and retrieve all stored codes, including C1507. Record the freeze frame data associated with the fault — these readings tell you exactly what was happening when the module first detected the problem.
Look for any accompanying codes in the C-series range. Codes appearing alongside C1507 often point directly to the failing component, whether it is a specific sensor circuit or the module itself.
Perform a thorough visual inspection of the wiring harness feeding the ABS and stability control systems. Check for frayed insulation, broken wires hidden inside looms, moisture intrusion, and corrosion at every connector.
Access the live data stream for all four wheel speed sensor PIDs and observe the readings as you drive slowly in a safe area. A faulty sensor will freeze, spike, or show readings that do not match the other three wheels.
Examine the tone ring attached to each hub. Metal debris, missing teeth, or physical deformation will cause erratic sensor output and trigger C1507.
After addressing any discovered issues, clear the code and complete a drive cycle that recreates the conditions captured in the freeze frame. If C1507 does not reappear, the repair is confirmed.

Repair Options and Costs

Costs vary significantly depending on which component has failed. Labor rates are based on independent shop estimates and will differ by region.

Wheel speed sensor replacement typically runs $120 to $350, including parts and installation.
Wiring repair for damaged sensor circuits generally falls between $80 and $250, depending on the extent of the damage and whether connectors need replacement.
ABS module diagnosis, repair, or full replacement is the most expensive scenario, ranging from $400 to $1,200 depending on whether the module can be rebuilt or requires a new or refurbished unit.

How Much Does Fixing C1507 Cost Overall?

The total bill to resolve C1507 depends entirely on the root cause. Most diagnosed cases involve either a failed wheel speed sensor or simple wiring issues, both of which land on the lower end of the cost spectrum. Module replacement becomes necessary only when internal electronics have failed. Expect to spend anywhere from $80 to $1,200 when all factors are considered. A proper diagnosis before purchasing parts is the single most effective way to control total spending.

Can You Drive With C1507?

C1507 carries a caution severity rating. Your conventional brakes will continue functioning, so the vehicle remains drivable under careful conditions. However, the antilock brake system and electronic stability control will not intervene if you encounter a sudden stop or lose traction on wet or icy pavement. Stopping distances increase noticeably in these conditions. The fault should be addressed promptly, and aggressive driving should be avoided until the system is restored.
