I hope this is right place:

Can anyone please recommend a semi-professional scanner tool that has bi-directional capability? I'm a DIYer but want to get more into diagnostics. My daily driver is an 06 Suburban, but also have a 99 NBS, a 13 Chrysler Town and Country and a '20 Express passenger van.

My mechanic replaced the heater core on my suburban and I have to reset the airbag because the light is illuminated on the dash. Also has the tmps light.

I parked the Chrysler months ago because the battery was not charging. I recently bought an older scope and diagnosed it as a bad pcm ( no PWM signal from PCM.) Ordered a new remanufactured PCM and battery is now charging, but it seems I need to relearn the TPS? My basic Innova handheld doesn't do this. I'm pretty much my own mechanic nowadays out of necessity.

Thanks in advance!

 

Not sure if this works with other makes...

The way to reset the GM TPS sensors is to unplug the sensor > turn key to the run position for 30 seconds > turn off key > re-plug TPS sensor.

 

I like the Autel MK808. I almost bought a Tech 2 clone but after a lot of thinking I went with the Autel.

 

Well, I got to messing around with my Innova 5610 handheld scanner and it turns out it has SRS and some other features I wasn't aware of.

I hooked it up to my Suburban and found a bunch of Bxxx codes on the passenger side airbag. Open, out-of-range and something else. Found a yellow connector under the driver seat unplugged (that was me when I removed my center console,) and a yellow connector near the passenger side airbag module unplugged (probably my mechanic.)

I cleared those codes and no more airbag light! I'm down to the TPMS light. 🤭

 

I also messed around with the Mopar minivan, but no progress on that one. I have some TCC and other transmission codes, and the accelerator pedal codes. I was hoping to do a TPS relearn, looks like this scanner has that capability. But I can't connect to some modules, including the transmission module. 🤔

The gas pedal has no response if I depressed it.

So to recap on this vehicle: the ECU was replaced with a remanufactured one (because the alternator wasn't charging, which now seems fixed) programmed per the VIN. All of these codes popped up after that. One of those ratcheting ECU connectors got stripped when I removed it. I put a zip tie thinking maybe it wasn't making good contact, but no dice.



Any Mopar guys around? I'll swap back the old PCM and see what happens 🤞

 

Well, I'll be damned. I popped in the old ECU on the 3.6 and everything works! Gas pedal, no TCC codes and I'm able to see the modules. I do have a permanent low voltage code, which was obviously the problem to begin with. It's looking like I got an ECU not programmed for this vehicle. Doh!

I'll call the ECU folks and hopefully they can send me the right one.

 

Unfortunately this happens...

 

I got my ECU in the mail. They warrantied it. I just had to fill out a form on diagnostics, symptoms, and codes.

I just hooked it up and everything works! I have to button everything thing back up, but I think she's fixed!



No more money light!

 

So I ordered the Autel TS508 kit with 8 sensors from AES Wave for $285 for the annoying TPMS reminder on the cluster. It was cheaper than anywhere else. I need to figure out how to use it now.

My brother has a sensor bad on his Ram, so I'll probably sell him a sensor and reprogram it for him.

 

I finally got the 2 front TPMS sensors replaced on my Suburban. Programming them was pretty easy and it was $10 at my local tire shop to swap them. No more annoying dash lights!

In other news, this week I drove the Chrysler for a job I had in Lufkin and leaving my battery light came on. I went to the local O'Reilly's and they said my alternator was bad. The manager was nice enough to call some local shops but no one was available. Long story short, I had to replace it in their parking lot in the hot summer heat. Took me like 2 hours, taking it slow. They loaned me some tools. I got home okay. Sometimes you gotta do what you gotta do. 😒
