Code B11BA Lincoln Description

Voltage is sent from the Audio Control Module (ACM) or Accessory Protocol Interface Module (APIM) to the steering wheel controls, and the same module grounds the return circuit. The VOL-, VOL+, SEEK- and SEEK+ switches share signal and return circuits, while the VOICE, MEDIA, PHONE and OK switches share separate signal and return circuits. For all configurations, when a switch is pressed, the voltage is routed through a specific resistor value for each function. The ACM (or APIM) then uses the reference voltage to determine which control input function has been selected. The OBDII code is set by the ACM when the reference voltage to the steering wheel controls is out-of-range. This can be caused by a number of different failures on the steering wheel controls circuit except for a stuck switch or a short to ground in the signal return circuit.
