U1037 – OBD-II DTC

OBD-II DTC U1037 – SCP (J1850) Invalid or Missing Data for Wheels

DTC U1037 meaning

DTC U1037 refers to a diagnostic trouble code indicating “Invalid or Missing Data for Wheels” in vehicles equipped with the On-Board Diagnostics II (OBD-II) system. This code is specifically related to the communication network using the SCP (J1850) protocol, which is commonly used in Ford vehicles. The code suggests that the vehicle’s control modules are not receiving the expected data from the wheel speed sensors or related components, which can affect various systems, including traction control and anti-lock braking systems.

DTC U1037 symptoms

Common symptoms associated with DTC U1037 may include:

• Illumination of the check engine light or warning lights on the dashboard.
• Inconsistent or erratic behavior of the anti-lock braking system (ABS).
• Traction control system malfunctions.
• Unusual vehicle handling or braking performance.
• Potential loss of wheel speed data on the vehicle’s display.

DTC U1037 causes

Several factors can lead to the triggering of DTC U1037, including:

• Faulty wheel speed sensors or wiring issues.
• Corrupted or damaged control modules.
• Issues with the SCP communication network, such as short circuits or open circuits.
• Software glitches or programming errors in the vehicle’s control modules.
• Physical damage to the sensors or connectors due to road debris or accidents.

DTC U1037 seriousness

DTC U1037 can be considered serious as it may affect critical safety systems like ABS and traction control. If left unaddressed, it can lead to compromised vehicle stability and increased risk of accidents, especially in adverse driving conditions. Therefore, it is important to diagnose and resolve this issue promptly to ensure safe vehicle operation.

How to diagnose DTC U1037

To diagnose DTC U1037, follow these steps:

1. Use an OBD-II scanner to confirm the presence of DTC U1037 and check for any additional codes.
2. Inspect the wheel speed sensors and wiring for visible damage or disconnections.
3. Test the wheel speed sensors using a multimeter to ensure they are functioning correctly.
4. Check the SCP communication network for continuity and proper voltage levels.
5. Examine the control modules for any signs of damage or software issues.
6. Clear the codes and perform a road test to see if the code reappears.

How to fix DTC U1037 step-by-step instructions

To fix DTC U1037, follow these step-by-step instructions:

1. Start by inspecting the wheel speed sensors for any physical damage or corrosion.
2. Repair or replace any damaged wiring or connectors associated with the wheel speed sensors.
3. If the sensors are faulty, replace them with new ones according to the manufacturer’s specifications.
4. Check the SCP communication network for any faults and repair as necessary.
5. Reprogram or update the control modules if software issues are identified.
6. After repairs, clear the DTC using an OBD-II scanner.
7. Perform a road test to ensure the issue is resolved and the code does not reappear.

How to erase DTC U1037

To erase DTC U1037, follow these steps:

1. Connect an OBD-II scanner to the vehicle’s diagnostic port.
2. Turn the ignition key to the “On” position without starting the engine.
3. Access the diagnostic menu on the scanner and select the option to clear or erase trouble codes.
4. Confirm the action and wait for the scanner to complete the process.
5. Disconnect the scanner and start the vehicle to ensure the check engine light is off.
