Car Forum / Oldsmobile Cars / June 2005a/c code....what does it mean???
Gentlemen; a/c quit working and i’m getting a code 38 (serial data line)......what do i need to do to fix this? The heater and blower all work....its just that the a/c compressor doesn’t want to kick in. Any help would be greatly appreciated. Its a 1991 olds 98........... Thanks Northstar Where did code 38 come from, the bcm or pcm, code 38 is a TCC circuit problem, did you access through the a/c control like Cadillac? > Gentlemen; > [quoted text clipped - 6 lines] > Thanks > Northstar > Where did code 38 come from, the bcm or pcm, code 38 is a TCC > circuit [quoted text clipped - 24 lines] > ----= East and West-Coast Server Farms - Total Privacy via > Encryption =---- Shep..... The code came from the climate control unit.....(a/c contols).....The manual i have says a code 38 from the a/c unit is a "serial data link problem".... but after that, the manual says nothing.....Thanks for any info you can share... Northstar Generally this refers to the communication from the bcm to the control unit, specifically what is wrong , you will need the Cad manual, or an Alldata subscription. > > Where did code 38 come from, the bcm or pcm, code 38 is a TCC > > circuit [quoted text clipped - 34 lines] > > Northstar Generally this refers to the communication from the bcm to the control unit, specifically what is wrong , you will need the Cad manual, or an Alldata subscription. > > Where did code 38 come from, the bcm or pcm, code 38 is a TCC > > circuit [quoted text clipped - 34 lines] > > Northstar > Generally this refers to the communication from the bcm to the > control unit, [quoted text clipped - 71 lines] > ----= East and West-Coast Server Farms - Total Privacy via > Encryption =---- Shep...... Specifically, everything works except the a/c....fan/heat....but the compressor does not engage. I got a flashing temp light on the control unit signaling a problem, entered the climate control computer, and it gave me a code 38. I’m just looking for a place to start.....Thanks again Northstar |
