Works on 2007 Honda Odyssey AC Relay
I had the dreaded intermittent AC failure on my 2007 Honda Odyssey. I've also had a long term parasitic draw that could be related that I have been unable to track down. I took it to the mechanic; the system was low on charge with a leak at the Schrader valves.Valves replaced, system charged, and the compressor would still not stay on. I came in as the mechanic (very good and honest guy) was scratching his head and diagnosing the wiring to the compressor and asked, "do you think it could be the relay?" He swapped the relay to the compressor with a jumper and the compressor kicked right on. He swapped a known good relay in and the problem was solved.I bought the ES 193 so that I can save time and effort by quickly checking the relay myself in the future. Is it cheap, no, but neither is AC diagnosis and repair. Is it quick and easy to check myself (I'm handy and can lookup how to bench test a relay, but I want easy right now), absolutely yes. I checked all the remaining relays (five in total) in about 3 minutes; they all passed (the suspect one failed but it does have a small hole in the side from me pulling it out with a pair of hose pliers to replace it with a new relay after we had already diagnosed it as probably bad).

Complete kit
It worked very good. Harder to get relays out than it is to test them ! Only thing is having to hook up to 12v source. But you don’t have to worry about batteries going bad.

Amazing!!!
This is an amazing tool and a is must to have in your tool box for 12/24v electrical diagnostic. I had it for several months and used it many times, works as it should every time. I regret not buying it years ago. Strongly recommend.

Great tools
It works really great. It is identical to MATCO just a 1/3 of the price.
