I recently installed 2 amps in my accord sedan EXL. 1 in trunk for sub, 1 under (what was going to be under when put back in) the passenger seat. Normal install, power wire (0ga down driver side to rear trunk spare tire area(spare tire removed) to a power distribution block, 2 8ga. Trunk 800w 2ch grounded to rear body panel common ground point just to the left of the rear body panel trim.

Power wire for 1200w 4ch from power block travels under center of back seat (secured and covered) up the side of the cabin middle hump that rests center console. Then out to cut slit just to the side of the passenger seat console gap. Grounded to common ground point right under that carpet.

NOW, after that was fully installed. And working perfectly for 4 hours. I installed back the center console. placed back radio dash with pioneer touchscreen.

I go to start my car. Turns on then suddenly 3 seconds later, my instrument cluster goes dark. Turned off my car, Turned it on again, no sign of power in instrument cluster, then engine stalls out fast 3 seconds later.



(I have already done:
----- replaced 3 relay fuses under driver side dash Fuse box
----- Tested battery and alternator, also current of battery for the 3 seconds car is fully on
----- Verified all fuses on vehicle are good (They are)


I pulled out the instrument cluster and found (what looks like to me) is a shorted out section of the green board, right behind the fuel level reading dial.

I pulled these trouble codes from the OBDii

U0155 - F-CAN Malfunction \ ECM/PCM Gauge Control
(shows to be Lost Communication With Instrument Panel Cluster (IPC) Control Module)




The issue still continues, starts, then stalls. After i replaced the ACCESSORIES relay in teh fuse box under driver dash, the illuminated interval rings light up. But when car starts no red dials/mileage power.

Anyone help?

Hello
You might have to reset your ECM, refer to your manual. Or just unplug the neg or both to make sure out of battery for 15-20 minutes then try again. Maybe it needs to reprogram itself. Update please. See if that fixes this issue.

SORRY for the late update. It turns out that there was in fact a short somewhere in the system. Somehow, someway, the PCM internally fried. I ended up after doing the PCM reset the manual way and also hooked up to a friends Honda Service Tool that the PCM was now bad. I ended up replacing the PCM with a used PCM, yep, a used PCM for $60 bucks. All that needed to be done was change the VIN in the PCM and perform the ILP after. Car up and running wonderful for 2 months now.
