Thread: ABS Light, no code - EBCM?

Hello again, all.

So on the new (to me) 98 GTP, it had both airbag lights and ABS lights. I couldn't pull any codes for either with my scan tool. (Palmer ScanXL, with Elm 327 bluetooth connector.) I have scanned and found ABS codes on a couple of different 2004 Impalas, and a Monte Carlo, so I'm 90% sure it should find the codes here, but not 100%

Anyway, I replaced the airbag module with an ebay unit quite cheaply (old one had the classic corrosion from the blower motor water intrusion). SRS system is fixed.

So, when I key on, the light comes on solid and immediately. No flashing, no going out and then coming back. It is on constantly from the moment the key is turned to ON. It doesn't go out for anything. But no codes. With my voltmeter, I tested the pins of the module connector... the two red wires are delivering power, and the pink wire (which I believe is ignition signal) is getting power. Checked that all fuses were good as well, particularly the A/C / ABS fuse under the hood. Connector pins are in great shape on both sides of the module.

I've read that this module (Bosch 5.3?) is pretty common to fail, but I haven't had it on one of my cars before. Is it pretty safe to say that my module is shot, since it won't feed back any codes, or do I really need to get another scan tool and try again? I feel like I should at least be getting a code from the BCM saying that it can't communicate with the EBCM, but I'm really not positive. Thoughts?

98 abs info like you are looking for is not in the pcm, it's in the body or abs modules. HPT wouldn't give me anything until about 2000. Then it's in pcm.

Sh*t guys, major f-up in my description. It's a 2003 GTP. I have no idea why I said 98. I'd fix OP but for some reason, I'm having issues editing it. It just gives me a blank box.

And I have repaired the wiring harness to the hubs before on other models...but those generate a specific code, and usually the ABS light goes out, then comes back on. At least, from my recollection that's the case.

I have HPT also...think I should try to find ABS codes with that as well?
