Testing Electric Fuel Pump Problems with Voltage Drop Test

Possible causes
- Faulty Powertrain Control Module (PCM)
- Powertrain Control Module (PCM) harness is open or shorted
- Powertrain Control Module (PCM) cicuit poor electricl connection
- Low battery voltage

reset the CPU using a code reader as the program may be corrupted

i would say tis is an electricl problem

im not sure what your talking about, it sounds like you want the wiring for the cluster, but this doesnt control brake,tail or headlights, the brake lights operate through the brake light switch and go through the signal light switch to power those up. the headlights and tail lights work through the head light switch, what system do you need, or what doesnt work.

if its not the lamp lense gone cloudy then I would just try replacing the bulb first.

you should be able to just unplug the wiring harness by pushing in the tab and pulling apart

Yes, this should work, all you need to do is to un bult the 4 bolts on the bottom of the seets that are attached to the floor board. And just unplug the electricle

you likely just need to change the relay in the fuse box... i'm not sure which one it is tho
