How do i get the collision alert signal to work ?

Automotive vehicles are increasingly being equipped with collision avoidance and warning systems for predicting the potential collision with an external object, such as another vehicle or a pedestrian. Upon detecting a potential collision, such systems typically initiate an action to avoid the collision and/or provide a warning to the vehicle operator. The aim is to design and develop a control system based on an automatic, intelligent and electronically controlled automotive braking system for automobiles is called as "INTELLIGET BRAKING SYSTEM". This Braking system consists of IR transmitter and receiver circuit and the vehicle. The IR sensor is used to detect the obstacle. There is any obstacle in the path, the IR sensor senses the obstacle and giving the control signal to the microcontroller, which in turn sends a signal to the motor to stop and also to the solenoid so as to stop the vehicle as programmed. This project facilitates electromagnetic braking system using solenoid. Here in fabrication module include a circular disc associated with a dc motor and a solenoid. Embedded system module includes micro controller with a solenoid and sensor

You can Disable that warning. The body shop probably unhooked the battery and this reset the warning. In any collision, the body shop is supposed to have a mechanic check the rest of the vehicle. Take it back to the shop. The temp sensor could be having issues on the air flow sensors.

did i miss anything

Check the reset switch near yo icu. reset it if off

There is nothing in the wiring diagram that would cause the pump not to run because of a wreck. The pump is powered by a relay and a fuse, the relay is activated by the computer.
If the pump relay is not getting a ground signal from the computer the computer may have to be flashed with a scanner.

You must understand that collision stresses the ENTIRE vehicle. Just because it was hit from behind, does not mean that there is not collision damage in the front. I had a vehicle in my shop several years ago that was hit from the rear. The engine began knocking shortly after. It turned out that the collision had jarred the engine hard enough to cause the crankshaft to crack. This type of damage is extremely rare, but can happen. Trying to convince the insurance company that this was collision damage was a real trick.... On the other hand, fuel sending unit failures are quite common (without any collision) and can cause your fuel gauge to stop working.

The only way to determine if your problems are caused by the collision would be to first diagnose the problem. Only then can it be determined if the current failure is caused by collision or possibly caused by a more commonly known failure type.

Sounds like a ground problem, and the turn signal is trying to use another path to ground, causing the other lights to glow.

Check the left side bulb socket for a good ground.

The other test is to pull the L & R Stop / Turn fuses for the trailer tow adapter, to make sure the problem is not with the 4 or 7 pin trailer adapters.

have ur abs checked one of the sensors may be corroded or damaged causing the abs to activate at low speed and usually doesnt give an abs light need the resistance read on sensor

run a new ground to this light and see if it works!!
