What Leeds you to believe it faulty? I would think if you go to AZ AUTO OR PEP BOYZ ADVANC. AUTO that any one of them could tell you very easily, good luck Bret

How do you tell if a brain box is out on a 97 mucury sable


brain box is out ?????? What problem are you having , what's not working ? Normally hooking up a scan tool to see if it will communicate . Checking for DTC'S - diagnostic trouble codes Etc.... Checking power and ground circuits to the PCM / ECM powertrain control module or electronic control module . Not brain box . If you are unfamiliar with this , do yourself a favor and take it to a qualified repair shop .

How do i change the Electronic Computer Module (ECM) in a 1996 pontiac 2.2 automatic sunfire


I would get a second opinion , there not the brightest people . Take it to a ASE certified repair shop or dealer . Does your vehicle start an run ? If the brain box was bad it probably would not .
Powertrain Control Module/EEPROM Replacement/Programming

Powertrain Control Module (PCM)
Notice: In order to prevent internal damage to the PCM, the ignition must be OFF when disconnecting or reconnecting the PCM connector.
Service of the PCM should normally consist of either replacement of the PCM, EEPROM re-programming or a KS module change.
If the diagnostic procedures call for the PCM to be replaced, the PCM should be checked first to see if it is the correct part. If it is, remove the KS module from the faulty PCM and install it in the new service PCM. The service PCM will not contain a KS module. DTC P0601 indicates the EEPROM programming has malfunctioned. When DTC P0601 is obtained, re-program the EEPROM. If a DTC P0325 is set, check the KS module for proper installation. If it is installed correctly and DTC P0325 is still displayed, replace the KS module.
The ignition should be OFF for at least 10 seconds before disconnecting power to the PCM so the IAC valve has time to move to the engine OFF position.

2002 chevy camaro diagnostic port not working I cant get reading when I plug into diagnostic port.


Check your grounds. Check on top of the port. I found a penny on the top of mine and it shorted out the brain box. Take to autozone, orielly's or advance auto to get hooked uo for FREE. They might help. I had to replace the brainbox.

Where is the brain box jack for the honda accord 1997 model


Oh, you must mean the diagnostic connector. I think on all post '96 vehicles it's just beneath the dash on driver's side, protruding out a little from bottom edge of the dash.

My chrysler cirrus 2000 model is not starting, a mechanic said the brain box is bad, we have tried over 7 other brain box without any luck, what can i do to get the car working?


It seems that if you tried that many brain boxes, one of them would have worked.

Here are some things to check. (I am assuming you have gas in the tank, the battery is good and the engine cranks over but doesn't catch and run.) Perhaps one of these items was overlooked in the trouble-shooting:
Engine cranks but won't start:
Charcoal canister full of fuel, faulty MAP or MAF sensor, faulty engine coolant temp sensor, faulty EVAP canister vent valve, EGR valve stuck open, lack of or incorrect fuel pressure (fuel filter, fuel pump, fuel pump relay), water in fuel, fouled spark plugs, faulty ignition module, severe vacuum leak, severely clogged fuel injectors, wrong size o-rings on fuel injectors (prevents compression), faulty airflow sensor (if equipped), Idle Air Control (IAC) valve defective, disconnected-broken-loose wires for all of the above.
