Hello all, been a while since I last posted but I have been browsing around silently. As the topic suggests, I have had my VSA warning light come on. I have browsed around a bit and know that the VSA module isnt exactly the most reliable component on these cars (gen 7 2006 diesel). Car has been absolutely perfect over the years however decided to throw its toys out of the cot. Arrived home the other night, all was fine with the car, turned it back on the next morning and the VSA light was on. I did the basics, checked the fuses etc, all of these were fine. I have worked on many cars but never with stability control systems. I have an OBD reader however, as I soon learned, it doesnt read ABS/VSA codes, only engine ones. I tried the old trick of jumping the OBD plug (connectors 9 and 4), which took the care into service mode. The dash flashed up "DTC - NO" which, from my research means that there are no active error codes. Is this correct? The ABS light, being now in service mode, started flashing its code, and counting them up, came with 61 and 66. Further research has suggested that 61 is a power issue of the VSA modulator either being too high or too low and that 66 is a pressure sensor issue within the modulator. The ABS light is not on and the ABS system works fine (tested it) I see that a member has changed this themselves before VSA Module Change (Diesel) • Honda Karma Does the new modulator need to be programmed in at all or can I just get a refurbished one and change them over? For the past year or so, every time I have started the car from a cold start, it clicked whenever I hit 10-15 mph, clicked in the sense where it would hesitate ever so slightly for a split second. Sounded like a relay was kicking in,but it would cause hesitation. Ever since the VSA system has disabled itself a few days ago, this click no longer happens, so I am starting to think that it was the VSA module that was already showing signs of failure, but something that I could never pin point. Is this possible? Anyway, found a new module here HONDA ACCORD 2.2 ABS (PUMP & ECU/MODULE COMBINED) - Part No: 57110-SEF-E610-M1 / 06210906613 Which coincides with my exact part number. Can someone explain to me how the DTC shows that there are no errors, but the old fashioned method of the flashing ABS light shows two error codes. Does the DTC over write itself? Does it remove an error if that error then fixes itself? If I take the car to Honda for a scan, are they likely to just say there are no DTC's recorded or, I am assuming from reading on here, the systems they use are much cleverer than that and can discover faults regardless? Thanks all, sorry for all the questions, just trying to get my head around this VSA.
