BCM Output Displays

Output displays are operated as defined under SELECTING TEST  . When trouble shooting a malfunction, ECM and BCM output cycling can be used to determine if output tests can be actuated regardless of inputs and normal program instructions. Once a test in outputs has been selected, test will display "HI" and "LO" for three seconds in each state to indicate the command. The following are a summary of each parameter for BCM:

1. BO00 - NO OUTPUTS
   
   The display will not display "HI" nor "LO" as this is a resting spot where no outputs will be cycled.
2. BO03 - RETAINED ACCESSORY POWER (RAP)
   
   The relays display is "LO" when the relays are on (energized).
3. BO07 - PARK CONTROL
   
   Will cycle the Park output to the memory seat. Reads "LO" in Park and "HI" in all other gears.
4. BO09 - REDUNDANT RELAYS
   
   Will cycle the Redundant Relays with the headlamp switch on, which will light the left low beam headlamp and left rear tail lamp. The relays are activated with the "HI" reading.
5. BO10 - CHIME OUTPUT
   
   Cycles chime output to chime module. Chimes will not be activated with key on.
6. BO11 - CENTRAL DOOR UNLOCK
   
   Will cycle the unlock coil of the door lock relay.
7. BO12 - THEFT DETERRENT DISABLE
   
   Cycles the disarm output to the theft module. The display is "LO" when disarm is commanded. The engine must be running for this output to cycle.
