Ecm bcm error code f32 was on smelled something burning now its not coming on and car has been stalling

Do you know what is involved in starting your vehicle ? Looking at a wiring diagram to see what's involved is the first step in the diagnostic procedure . What engine ? 2.0 l or 2.2 l Hooking up a scan tool an checking for code's for the BCM - body control module would also be a good step . The ignition switch is a low voltage input to the BCM .When start is requested by moving the ignition switch to start , the BCM sends a start request to the ECM - engine computer which will energize the crank relay sending battery voltage to the S terminal on the starter solenoid , spinning the engine over . This all happens in milliseconds ,if the ECM see's a input from the park neutral switch an no problems with the anti-theft system .

Circuit Description
Moving the ignition switch to the START position signals the body control module (BCM) through discrete inputs from the ignition transducer that engine crank has been requested. The BCM verifies that theft is not active and sends a serial data message to the engine control module (ECM)/powertrain control module (PCM) requesting engine start. The ECM/PCM receives a 12-volt signal from the park/neutral position (PNP) switch or clutch pedal start switch notifying that it is safe to start the engine. There is a splice on this circuit in the fuse block-underhood that supplies power for the starter relay coil. The starter relay coil control circuit is then grounded by the ECM/PCM closing the switch in the starter relay suppling 12 volts to the S-terminal of the starter. Ground is supplied through the engine block.


Your best bet , take it to a qualified repair shop.

Are you loosing radiator fluid. sometimes the heater core will rupture and you will smell burn odor. also check for strange rubbing sounds or screeching coming from the blower fan motor. or engine exhaust manifolds are hot when car is on, make sure nothing is leaning on them which will cause a burn odor. Any odor coming from outside will find it's way inside through the fresh air vents.

Check the ECM part number. If it is a 1228253 that is your problem. get a 16198264 the other number does just what your car is doing. I worked at a Buick dealer and know about the problematic 1228253 ecm.

Ok, check the thermostat, and it is easy to replace. Subarus have small radiators, could be clogged. Are your electric fans coming on? Are you losing water? Also may be a bad head gasket or cracked head. Of course, check all the hoses, including the heater hoses. The smell could also be oil leaking onto the exhaust pipe. Subarus are famous for this. But that will smell like oil, not antifreeze. Mainly, check to see if you are losing water. Also, there is a bleeder outlet on top of the radiator on the opposite side of the cap. usually the left side, if you add fluid to the radiator, do it very slowly and take off that bleeder, phillips head screw, until coolant comes out of the bleeder, then you know there is no air in the cooling system, If there is the subarus will overheat quickly, especially under a load.

no but a low fluid level could cause a slip telling the ecm there is a slip top it off then clear the code and drive a few miles if this code comes back i would say there is internal damage to the tranny

most auto-zone or Midas shops will do a scan for free so long as the chk engine light is on try checking all fluid levels in your vehicle 1st it could also be wise to do a visual check of your wires and vacuum lines as well as just a low level of maby oil or radiator fluid even brake fluid level start with that area 1 st

When the engine is cool, check the fluid level in the radiator. If low add 50/50 solution of water and antifreeze. Do not continue to drive your car until this is fixed or you could cause a lot of damage to the engine.

Code eo52 indicates that the "long term" memory in the ecm has been reset. You will get this code when power is removed from the ecm. B448 is low refrigerant pressure. B552 indicates that the keep alive or "long term'' memory in the bcm has been reset ans a result of power being removed forom the bcm. What is a TPC? The throttle position sensor should be set at -1.0 to +1.0. at lowest position by the ICS motor. The throttle position sensor should be set at 10.5 to11.5 when the ICS motor is at its maximum extension. This is done by the ICS plunger adjustment is at its lowest point. . A mis adjusted TPS sensor will result in a great loss of fuel mileage. It appears the converter is stopped up on yours.

Of course, check the fluid first. Running, pull the stick out, wipe it and put it in, pull out and read it. If fluid smells burned, it probably is. (indicating an internal problem) If low, add till full and try to move vehicle. Check for evidence of leaks underneath & repair before driving. Even if it does move, it's likely that something has been damaged somewhat from driving with low fluid... At the least, have the fluid changed, to prevent burned fluid from causing more damage.
