1995 Bonneville SSE

I recently purchased an Actron CP9145 Super AutoScanner which, as their website states, is one of the ones required to read the engine codes however I still can not communicate. Actron service tech has yet to be helpful or shed any light onto the problem.

Driving home from work check engine light came on and car feels as though it has a miss, checked all sparkplug wires with inductive pickup and they all appear to be getting a signal. Plugs, wires, and O2 sensor changed ~1-2 years ago. Would love to be able to read the engine code to point me in a direction.

Also have the problem with the car shutting off while driving, will not start for what appears to be random amounts of time - sometimes 5 minutes sometimes 3 days. Would this still indicate a crank position sensor problem since it does not appear to be heat related?

Temperature display on climate control flashes for like a minute or so when key is turned on and/or car is started and then stays on, asked dealer and was told to wait until it completely fails as trouble shooting would cost more than car is worth. By the way AC is not working I believe it to be an interlock somewhere. It does hold a charge and I believe the compressor and clutch to be in working order.

Driver information center blinks in and out causing trip mileage etc. to reset, plus the occasional loud obnoxious noise emitted from one of the rear speakers.

Seems like a bunch of electrical issues, maybe the ground connect under the carpet? Water leak on passenger rear side, carpet gets very wet and am not sure where it is coming from although suspect the rear window.

Sorry for the long post.
Help to any or all of my issues would be greatly appreciated....Anyone want to buy a car?

I'm not sure why its not communicating I know you can use the Actron CP9110 (with gm cartridge and gm obd2 style cable) to read codes as well as stream data.

it should work with a 84-95 as well. with the correct cable. CP9145 works fine with other members here with the OBD 1.5 cars.

I went back to re read the site and i was wrong.

jr's3800 has an Actron 9145 and a '94 or '95. I have an older Actron 9110 with a GM cartridge and a homemade cable that I use on my '95.

Also, my '95 did the random stalling thing. Turned out to be the PCM. Computers for '94 and '95 are more troublesome than other years.

for the electrical issues i would check the Ground Buss....

as for the water leak issue I would suspect the door seals shrinking or the sunroof (if equipped) having the drains blocked or disconnected

Ground buss.. yes.. Pat..it'* possible (but you need to say where it is.. )

There is one under the front carpet on each side of the car. This is a rectangular item that is taped to the wiring harness. Water issues under the carpet will corrode the ground and cause isses.

On the misfire..double check that no plug wires are touching the wires for the O2 sensor. That will cause a mislike feeling.

I do feel that this sounds much like a PCM though. Await Jr's3800 to see this, he'* like the resident expert on bad pcms and knows the usual symptoms.

Climate control has sensed a fault in the system somewhere. Try searching on calibrating it etc. Echo SSEi is one of the experts with that system.

Hang in.. you'll get it going right soon.

Corroded battery cables (inside the sheathing/shielding) are also quite common for the stalling issue.

For your DIC, try the Techinfo link at the top of the page. There'* an article regarding removing the cluster and cleaning the contacts.

The CP9145 should communicate with no problem. Make sure the key is in the "ON" position, then enter the vehicle type, etc. I scanned a 95 this weekend and noticed that it asked for an engine type 1 or 2. IIRC, you need to highlight and select "1".

The tech-help at actron also suggested selecting engine type "1" I tried that and still got no communication. Should the tool be hooked up prior to turning the key to on or should the key be turned on and then the tool connected. I think I already tried both ways with no luck.
