rockfangd Posted July 6, 2015 Report Share Posted July 6, 2015 The code IIRC means that 2 outputs occured at the same. It will throw a code. Someone else may confirm on this. As for the squealing noise I would check your belt and tensioner. Also check the fluid level GM FAN FOREVER Nice, clean, luxury= fine automobile Link to comment Share on other sites More sharing options...
Bruce Nunnally Posted July 6, 2015 Report Share Posted July 6, 2015 Ref http://drupal.caddyinfo.com/?q=node/150 One of the audio buttons on the steering wheel is stuck Eight steering wheel control switches are used to control four audio and four HVAC functions. When the vehicle is equipped with the cellular telephone option, four telephone switches take the place of the HVAC steering wheel controls. The steering wheel controls are configured as a resistive ladder network connected to the dash integration module (DIM) across connector C1 terminal B3 and connector C2 terminal A1. When the vehicle is in ON, ACCY or RAP, battery voltage is provided from the DIM on CKT 1796 (DK BLU) to the steering wheel controls. Pressing a switch (or switches) causes a voltage to appear on return CKT 1375 (PPL) which has a value unique to the switch(es) pressed. Conditions for Setting the DTC DTC B2511 only sets if B1982 or B1983 is not current in DIM memory. DTC B2511 sets if the DIM determines that one of the audio steering wheel controls switches is stuck.
