avistart 6501 on accord 2000

My brother bought a car which has the Avistart 6501 installed by Good Guy and now they no longer in business so we will try to troubleshoot the problem. Basically, when he tried to do a remote start it does not start and the D4 light is flashing. After that the check engine light come on and he has to clear it by disconnecting the negative battery cable? Does anyone have any idea on where you should start checking?

Do you know if the R/S ever worked? When the D4 light comes on can the car be started with the key? A flashing D4 indicator light means that there is a fault in the transaxle electronic control system. If it worked in the past, I would check that all of the power connections are solid. You can check what code is being set by putting the ECU in diagnostic mode. Depending who you talk to it is either pin #1 (SAE standard) or pin #9 (Honda standard). In either case it is in the same location. The attached image is the Honda standard, so you are interested in pin #9. This is viewed from the terminal side NOT wire side. The procedure is as follows: 1. Make sure your ignition switch is off. 2. Ground pin #9 (brown wire) with a jumper. 3. Turn key on (engine off). 4. The D4 light will start to flash. The flashes correspond to the codes listed below. The first digit are long flashes and the second digit are short flashes. Single digit codes are all short flashes. Example - code 23 will be 2 long flashes and 3 short flashes. 5. Once complete, turn off ignition and remove jumper.

All circuits should be verified with a digital multi-meter prior to making any connections.

Thanks for the advices. I'll look at his car when I have a chance.

The remote start worked when it was first installed but after about a year, it stopped working.

did you get a chance to pull fault codes?This information is provided only as a reference.

Thanks for checking back. My brother is busy with school now so I'll check that out whenever he's available.

Finally I had a chance to do a quick check. It looks like someone has reconnected the starter wire back together (no longer connected to the Yellow - starter interrupt switch side and Violet - starter interrupt starter side). The rest of the wiring remains intact. I think that's the reason why the remote start did not work. I'll try to reconnect it this weekend and report back.

I've reconnected the starter wires according to the chart in the installation guide and I was able to remote start the car however, whenever the car is remotely started, the D4 light kept flashing constantly.  Starting with the key does not cause this problem. 

I've read the code with the scanner and the code was P0758 which is "Shift Control Solenoid "B""
