The light is on because the control module for the system has detected a fault in the system. You must now have the TCS scanned by the dealer to see what fault codes show up and then based on the fault codes do the diagnostics required and locate the problem. Once it is repaired the light will shut off. Right now you have no traction control system, it is turned off.

You have to drop the gas tank if that is your question.

The neutral safety switch which also powers the backup lights is a black switch mounted on a metal plate, so I would guess it is mounted to the shifter or the transmission. If you have a column shift check the bottom of the column, if it is in the console look around near the shifter.Otherwise it would be on the transmission near the shift lever.

Have a friend lay/sit/crouch by the back of your truck(Where the tank is), and turn the key on. they should hear a "whirring" sound.If they do, the pump is fine(Check fuel filter). If they hear nothing, replace your fuel pump!

HelloWhen the service engine soon light (Also called the check engine light) is turned on this is to alert you to the fact that Powertrain Control Module (computer) has detected a failure somewhere in the systems it controls, this can be the transmission or the engine or emission system, there are fault codes set in the modules memory for these faults. What needs to happen now is to have the powertrain control module scanned with a special tool called an OBD2 electronic engine control scanner or a OBD2 code reader. Once the code(s) are read then you must perform the diagnostics for each code and make the appropriate repairs based on the findings of the diagnosis that was performed, this is called doing "Pinpoint" testing.
