hey guys.....maybe somebody can help, got a 2000 FRC, took it to the local chevy dealer to get my traction/active handling repaired and the service advisor told me it was some hydralic pump or the like.....also advised me to take the skip shift bypass out, I told him to leave it alone....when I picked up the vette the bypass was sitting on the passenger seat...anyway I reinstalled it the other day and now my engine light is on, I think there might be a certain order in installing but can't remember which post on the battery to disconnect...I have a code reader that also clearscodes but it comes back on after driving it awhile....sorry so long but any help would help

 

I don't think you need an external code reader to look at your codes; this ability is built into the C5's diagnostic mode which can be accesessed by pushing buttons in the sequence specified in your owner's manual. Anyway, take a look at the code(s), write them down and post them here. I believe the ECM looks for a resistence value that is provided by the CAGS bypass. For some reason, it may not be seeing it.

 

thanks Dave....I bought the code reader because it can reset/turn off check engine light etc., the cars internal code reader won't do that...anyways the code was for the cags system, the solution I need is the sequence for installing the bypass the correct way so the car will not reject it and turn the check engine light on

 

Normally, there is no special sequence; see:

By the way, I can read AND reset codes without an aftermarket code reader. The code will come back if the car's computers sense the same condition after a certain number of cycles.

The iCAGS does not have a sequence to install. With the car shut down you simple pull the connector wire from the CAGS loom out of its socket on the trans., then plug in the iCAGS to the trans and plug in the wire loom you just removed to the other end of the iCAGS: you just put it in series with the stock wires. It's done.

Check if you inverted the connector (it has a polarity and the connector is not symetrical). You may have a bad iCAGS - the unit has to have a specific resistance that matches the stock solenoid's I don't recall what it is, but regardless, matching ohms is the only "smarts" the iCAGS, but if that is off, if the connector is not pushed in hard for a good connection, or if it is inverted, you will get an error code.

by the way, there is a way to clear codes in the vehcile by pushing the right sequence of buttons without a controller, but I do not remember it. somewhere on this forum, way, way back, I posted a link to a site that has all the instructions. but it has been a year (from today, ironically) since i sold my vette, and I have just forgotten. Should be around on the 'net if you goggle, though.

 

Here is how to look at and delete codes:

When I installed the Diablo performance tune on my car it eliminated the 1-4 shift skip.
