So far I have NOT seen any success turning on PCM optional equipment. Can't get shaker head end DSP to turn on bass out. Show rear differential temp, or turn on the diff cooler pump.
I think part of the problem is even though we've fiddled some address's in the PCM. At startup the system checks all systems. With the DSP it doesn't see valid signal on amp enable. On rear cooler it does get a signal from the pump shaft turn line.
To check this we need someone with 12 speaker system to monitor the amp line. Also to watch see if rear oil cooler does spin check at key on.
How about look for error codes. unplug kicker amp, unplug rear diff cooler before key on to see if any DTC's are set
