It has to go to the dealer are someone that repares them. You can not check them yourself.
The module is located on the transmission hump in front of the gearshift under the dash. If you check under the cup holder, you will find two sets of wires going in and these will lead you to the module. The module also has the crash sensors built into it. Good luck
Hi, The Powertrain Control Module (PCM) is located inside the Air Cleaner Housing Assembly (the box that holds the air cleaner). This is located under the hood, on the driver side of the van. Good Luck
I can't make any promises, but I've got 94 Chevy using OBD1, like yours probably has too. In my manual this is what it says: Code 42:Ignition Control Module - "Check the wiring and connectors between the ignition module and the ECM. Check the ignition module. Replace the ECM".Code 43:Electronic Spark Control - "ESC module is not receiving a knock signal from the knock sensor. Check the knock system sensor, or the ESC module. Have the module checked by a dealer service department." Hope that helps, good luck!
ignition control moduel common problem ..
Check power to ignition switch with ignition turned on check the on position at back of barrel for power for starters, EA falcons have a thick film module which i think is located in the dizzy, which if faulty could burn a coil out.. good luck
First check all your fuses. If they are good, then check for voltage from the headlight switch. If you have that, then the Light Control Module is bad. There is a brown wire coming from that module that controls the tail lights, licence plate lights, and running lights. You can also check by applying 12 volts to the brown wire and ground. If your lights come on, then for sure it is the light control module located under the dash by the steering column.
There are a couple of things to check. Since I doubt both coil packs would fail at the same time, I would check the Crank sensor and EDIS Ignition Control module on the driver-side fender. The easiest way to check the crank sensor is with a DVOM at one of the pins at the module. I cant remember which one off of the top of my head though. If you are getting a signal from crank sensor, then check power and ground at the EDIS module. These usually fail and show signs with intermittent starting when hot and cold. Also check the crank sensor harness if you are not getting a crank sensor signal.
There should be some oversized fuses in a fuse block under the hood. Often they are on the firewall, behind a cover or near the battery in a fuse box. It's all just a guess since there isn't enough information to figure out what's really going on. There is a "lock out" in the control module. Disconnect the battery. disconnect the control module. Wait. reconnect the control module. reconnect the battery. Voltages should be correct.
Do you have xenon lights? The brighter/white light? what do you mean when you say the headlight has spark? If so you might have a control module, or wiring problem. Even if they are not xenon bulbs you still might have a control module problem, the headlights are controled by the front sam control module, located in the drivers side rear of the engine compartment. Re-check to see if you have power at the fuse, is it fuse 51? 7.5 amp. I believe this is the fuse to check, in the front fuse box under the hood.
it's located behind the headlight switch and push button 4wd control. the plastic piece just pops out to reveal the transfer case control module. good luck
Another thing to check is the actual cable from the cruise control module to the throttle body. It will be right next to the accelerator cable on the throttle body.
You take it in to the dealership and have them do it for free. My 2005 Vibe's control module recently needed to be replaced and it was covered under warranty. It's an extended warranty on '04-'07 models of the Matrix/Vibe and the Carolla. It's good for 8 years or 80,000 miles, whichever comes first. Check it out.
