Oil Indicator light on dash board not working, the wire connections have been checked

LIGHT INDICATOR AND WIPER ALL PART OF YOU SWITCH ON THE STEERING COLUMN .BUT FIRST READ YOU MANUAL AND CHECK ALL THE FUSES.INSIDE AND OUTSIDE THE JEEP.NEXT FOLLOW THE GROUND WIRE FROM THE BATTERY AND MAKE SURE THE WIRE IS CLEAN AND TIGHT TO THE BODY.MORE GROUND WIRE WILL FIND UNDER THE DASH BOARD CLOSE TO THE DOOR HINCH.
GOOD LUCK

make sure all the connections are good and check ground wires also..

1. If your oil pump is not working you need to replace it,
   there is an light indicator on your dash board, if the light stay on then you know for sure that's the problem, go to a reputable mechanic.

If you can't pull the codes from the pcm it has either died or lost it's ground assuming it has power. I would try to get a wiring diagram and check both the power and the ground for the computer itself, because it is what turns on the pump and the wait to start light.

Check for fuses and fusible links that may be tripped or blown.

Next, check for grounding issues someplace easy to reach like the heated seat connectors.

Most dummy lights work by choosing the warning light path over the circuit path when the circuit path is higher resistance. Which may explain your dash warning lights.

So, what I am trying to say is...you are looking for a open ground in a big big place....like under the hood at one of the major fuse/relay/fusible link points.

Check it out. Good luck and be careful.

If you mean that the oil light was illuminated on the dash, it means the vehicle has no oil pressure, or it is dangerously low. You should check the oil level immediately, and if it is full, you should have a mechanic look at it. It cannot be run or driven if the oil light is on! Being a 2008 I would assume it is under warranty, atleast the 60 month 60,000 mile powertrain warranty. The old Tundra 4.7 engines had problems with the oil pressure sending units, but I havent seen any new trucks with that problem, and no service bulletins.

wires are pinched and shorting together near the left (drivers side) trunk hinge. brake light power is feeding back through the reverse light wiring. this will also turn on the check engine light with a neutral safety switch malfunction code as the computer also sees this voltage in the reverse light circuit. Find and repair the wiring, pull the EFI fuse in the panel under the hood to clear the code. Hope this helps

Dash lights are fed through the headlight switch. If the headlights work, then you could have a bad switch. Before you go replacing the switch, get a wiring manual for the car and see if you are getting 12v at the wire that supplies the dash lights. I forgot the color of it.

Use OBE to read codes, find fault code and erase, you can buy OBE's at auto stores for around $120.00, brake light probably needs replaced, see a good mechanic to open dash...
