Hi I am new to this site & I hope you can help me I have a 1994 Volvo 850 Turbo I had a transmission problem on the weekend where the shift light would come on after 120 KMS ( Canadian) then it would lose gears once I stopped. I would have to stop & start the car to limp myself home. Once there I proceeded to check any code @ the A1 port which in the past the LED light would always came on dimly only to have a broken test lead, Today I replaced the test module with one from a 1994 non turbo 850 only to have the LED come on once I plugged the lead into port A1 brightly and would not give me any codes Any suggestions on the module light would greatly help, Thanks
