Background Information In order to support owners who are more frequently using non OEM tyres Honda have changed the software to ensure the i--DWS system works within paramaters. This will enbale onweners to take advantage of increased functionality and give more flexibility to choose non O.E tyre and wheel sizes. From technical analysis of CR-V I-DWS (Intelligent Deflation Warning System) it has been found that in some cases the I-DWS MIL has been illuminated due to the use of Non O.E (including winter) types of wheel / tyre sizes.The current i-DWS system is programmed specifically for use of O.E wheels / tyres only. In order to allow customers greater flexibility with Non O.E wheel / tyre sizes, a Non O.E wheel size option has been added to the HDS I-DWS menu.In cases where a owner has complained about repeated I-DWS MIL on and are using Non O.E wheels / tyre sizes, the ABS / VSA modulator should be updated using HDS software version 3.012.033 February 2014 or later to allow the Non O.E Wheel Size option to be selected. Note: Before the VSA modulator is updated the vehicle should be inspected to eliminate a genuine tyre deflation warning due to a puncture or incorrect tyre pressure settings. To Check the tyre pressures correctly following the recommendations below. 1. Measure the air pressure when tyres are cold. - This means the vehicle has been parked for at least three hours, or driven less than 1.6 km (1 mile). If necessary, add or release air until the specified pressure is reached. 2. If checked when hot, tyre pressure can be as much as 30 – 40 kPa (0.3 – 0.4 bar, 4 – 6 psi) higher than if checked when cold. 3. Set the tyre pressures according to the tyre pressure sticker on the vehicle door opening area. 4 Initialise the I-DWS system after any change to the tyre pressure regardless of pressure value change. Note: The I-DWS should also be initialised if the wheels are rotated such as in routine servicing operation. If you plan to use non OEM tyres please visit your dealer to get the VSA Modulator Updated to the latest code. Owners within standard warranty will received this update for free, outside warranty you may be charged for this. I would suggest to all CR-V owners regardless of what tyres you will use in the future get this update so you have backward compatibility and a trouble free operation with a wider selection of tyres. This will also be filtered down to other Honda vecihiles equipped with I-DWS.
