right here are the BCM instead of instruction in the diagrams below. Inspect out the diagrams (Below). Please let us recognize if you require anything rather to obtain the trouble fixed.
I have actually the truck listed above classic model. Newly the defense light has started coming on. Occasionally it will flash on and off going under the road. Occasionally it just stays on. Periodically I journey it and also it doesn't come on. I have a friend who is a shop foreman in ~ the neighborhood dealership. He says it is a sensor, however it is expensive come replace. He claims as lengthy as the light being on is not doing anything to the truck not to worry around it. Need to I worry? Thanks!
come me the sounds favor the BCM is going out which is common however we should inspect the electric connector for corrosion as well. Below is the ar of the BCM and also how to change it. Check out the diagrams (Below). Please let us understand what you find. We space interested to see what that is.
My trucks gauges choose do job-related on there own. Temp gauge, oil kpa gauge, fuel gauge normally go the end together. Battery gauge works on the own and also when the battery gauge kicks in my push button 4x4, power windows, strength mirrors, strength door locks all walk out in addition to it and also come ago in at the same time.
Hello, If I have the right to jump in right here it sound favor the BCM is out. To be sure allows do a can scan i m sorry is the future the automotive repair you can acquire a can scanner native Amazon for around $50.00. Right here is a video clip to show you how. (no subscription needed)https://youtu.be/InIlnsjOVFAHere is a overview to assist you step by action with accuse in the diagrams listed below to show you exactly how on your car to change the BCM. Inspect out the diagrams (below). Please let us know what you find. We space interested to check out what it is.
an initial when van is turn off radio, battery light and also mileage remained on, took out the fuse for the truck body controller assessory and it addressed it, truck worked normal after ~ that, then just today the wipers job-related intermitetly in the turn off position, will not totally shut off. Is this all connected to the truck human body controller? need to it it is in replaced, ns dont have alot the money to have it scanned or serviced, ns wanna shot and settle it myself. A regional junk yard has a used controller, have the right to I simply install it or will it need to be programed to my truck. Many thanks
hi dekpenek! You need to gain a scan test this video will display you how. Girlfriend can get a preprogrammed unit just offer your VIN once ordering it.https://youtu.be/InIlnsjOVFALet me understand what codes you retrieve. If you require the BCM change the accuse to perform so room in the diagrams below.
My defense light stays on all the time and also will not revolve off, have had actually several mechanics look at including dealer and also no appears to be able to narrow under problem. They originally pointed come ignition and keys however have now said the is not the problem. Next they want to change out neutral safety and security switch and also harness by the transmission. Next they have argued one of 2 modules may be poor either BCM or PCM. Hoping someone can acquire me a better suggestion based on experience. They pointed out that some 2001/2002 models had a problem with three wires in the steering column coming undone however felt that was not that.

Hello, I have seen the BCM out which reason this problem. Right here are the security mechanism wiring diagrams so you have the right to see how the system works and the ar of the BCM which will must be programmed come work. Body regulate Module (BCM) Programming/RPO ConfigurationImportant: If the module is replaced, programming the module through the suitable RPO configurations need to be done before performing the Passlock discover procedure.The BCM must be programmed with the appropriate RPO configurations. The BCM stores the information concerning the car options. If the BCM is not correctly configured with the exactly RPO codes the BCM will not manage the features properly. Ensure the the following problems exist in order come prepare because that BCM programming:The battery is fully charged.The ignition move is in the run position.The DLC is accessible.All disconnected modules and devices space reconnected before programming.Follow the SPS indict on the Techline Terminal and scan device to regimen the BCM.If the BCM fails to accept the program, perform the complying with steps:Inspect all BCM connections.Verify that the SPS Techline Terminal and scan tool have actually the latest software version.Passlock learn ProceduresRefer to PROGRAMMING THEFT DETERRENT SYSTEM components for the appropriate learn procedure.Important: after programming, perform the following to prevent future misdiagnosis.Turn the ignition off for 10 seconds.Connect the scan tool to the data connect connector.Turn the ignition ON with the engine OFF.Use the scan tool in order to retrieve history DTCs from all modules.Clear all history DTCs.I would try unplugging the BCM and then plugging it in again which can solve a poor connection issue.Check out the diagrams (Below). You re welcome let us know what friend find. We are interested to view what the is.Cheers, Ken
