P1380 Code: Misfire Detected, Rough Road Data Not Available (GM)

On General Motors (Chevrolet, GMC, Buick, Cadillac), the P1380 code means the computer is not getting the rough road data it needs to tell misfires from bumps. The ABS light often comes on too. It does not point to an engine fault by itself.

What the P1380 code means

P1380 is a manufacturer-specific code: the 1 in the second position means each automaker defines what it stands for, not the generic standard. The most widespread definition is the one used by General Motors (Chevrolet, GMC, Buick, Cadillac). If your vehicle is another brand, confirm the code text with a scan tool that supports that manufacturer.

General Motors (Chevrolet, GMC, Buick, Cadillac)Misfire detected: rough road data not available

GM uses the wheel information supplied by the ABS module so that it does not mistake bumps in the road for misfires.

The P1380 code shows up when the computer does not receive that data from the ABS. It often comes with ABS or communication codes. By itself it does not indicate an engine fault.

Before you repair anything, confirm the make, model, year and engine. With manufacturer codes, the same number can change even between engines from the same brand.

P1380 code symptoms

  • Check engine light on.
  • ABS light often on.

Likely causes of the P1380 code

  1. ABS fault that stops it from sending the data.
  2. Communication between modules. Confirm it with the tests in the diagnosis section.
  3. Wheel speed sensors. Confirm them by comparing their readings with the actual values.

How to diagnose the P1380 code step by step

  1. Read the ABS codes and resolve them first.
  2. Check the communication.

How to fix the P1380 code

  • Repair the ABS.
  • Clear the codes, then confirm the P1380 code does not return.

Technical reference data

  • The wheel data arrives over the communication network.
  • P1xxx codes are manufacturer-specific: confirm the definition with a scan tool that supports your brand.
  • Values are approximate: check the manufacturer data for your vehicle.

Brand-specific notes

Common on Chevrolet, GMC, Buick, Pontiac and Cadillac vehicles.

If your vehicle is another brand, check the table above for the meaning its manufacturer gives the code, and confirm it with a scan tool that supports that brand.
