I'm going slow, and the way it used to work is that all leds step in one-by-one, beeping rate increases as more leds light up and once all lit, solid beep tone, I'd be a few inches from the object.
- Are the sensors hooked up in the wrong sequence?
- Are all 4 sensors supposed to be the same or do the outer ones have a wider angle?
- Does anyone know what the part number(s) for these are?
- Is there a wiring diagram for these somewhere?
Any help/experience with these would be greatly appreciated.
First, why not just take it back to the repair shop that fixed the damage from the accident?
All the sensors are the same (Part #05137536AA, or later revision). I don't think there is a sequence for the sensors. They all report back how close an object is - an object behind just one sensor should have the same behavior as an object behind all sensors (for the most part). It will turn off if you were going greater that 11.2 miles an hour.
Do all of the lights activate when you first start the car?
What is this object that you hit?
If it is a strange shape/height/location relative to the sensors it may not have picked it up until it was right behind the car. According to the FSM: The sensors detection length from the rear of the vehicle is 0.3 meters to 1.5 meters. This area extends around the rear side of the vehicle. The sensor detection height from the ground is 0.2 meters to about 1.5 meters. ² Ensure that the rear bumper (sensors) is free of dirt and debris to keep the system operating properly. ² Jackhammers, large trucks, and other vibrations could affect the performance of the system. ² Ensure that the parking brake is not applied.
