Ugh. I'm freezing. I've been in the garage for a few hours this morning, and I need a break to warm up. It's 34 degrees according to my thermometer, and I'm losing dexterity in my fingers.

1) I think I've been using the wrong pin with the blinker. I think I may have reported codes from pin 23 (ATA)
2) Using the blinker, I get a "1" (no errors) from the infrared remote locking system, so I have some confidence that I can use the blinker.
3) It appears that carsoft reports a fault of "7" no matter which system I scan in analog mode.
4) Carsoft has never successfully connected to a digital system.


Finally, and most importantly- When I connect the blinker correctly to pin 30, I get no blinks. How should I be using the blinker to read SRS codes? I feel like I've been chasing my tail for the last three weeks.

On a boring, and possibly unrelated side note: I wanted to test several different SRS control modules, so I powered on the car with several different modules. when the module is not making a good ground contact, I get no warning light. It doesn't even flash at key position 2. When the module is finally installed with the grounding strap, I get a solid SRS light at position 1 and 2.

You should use the ground terminal in the socket under test to avoid earth loops, you are asking for problems if you try anywhere else

I have a code reader with a ground. I am using the ground and 12V from the 38 pin socket. I am able to read codes on several systems. I get no codes from the SRS system.


My last comment was in reference to the SRS control module specifically. There is a ground strap in the wiring at the control module, under the center console. When that ground is not in place, I get no SRS warning lamp.
