Condition
Some owners may comment on the "Low Tire Pressure" message appearing or illumination of the "Low Tire" lamp. After checking the vehicle tire pressures, owners have indicated that none of the tires were found to be under inflated 12 psi (83 kPa) or more in comparison to the other three assemblies. This condition typically can be duplicated by operating the vehicle over a rough washboard type road surface.
Correction
Replace the existing EBCM/EBTCM with a new component selected from the table below. To determine the correct part number to order, locate the ECU PN (1) as shown in figure below, on the existing EBCM/EBTCM label. Then refer to the chart below to determine the correct service part number.
