The BCM controls the lights. wipers door locks some of the HVAC, security sytem and so forth. If this goes out you could find yourself stranded if the security system lock you engine down or won't allow the doors to unlock, you lights inside could go crazy, windows will quit working, your car could become Haunted!

It's not too difficult to replace the Body Control Module. If you know what you are doing you can do it in about 2 hours. The BCM is mounted on the back of the fuse box under the dash on the driver's side.

1. Disconnect the battery.
2. Remove the under-dash panel (plastic cover panel, metal panel, and metal brace.) You will also need to disconnect the handle for the emergency brake.
3. Remove three large screws holding fuse box in place (two on right and one on left.)
4. Remove the electrical connections at the bottom of the BCM. Avoid breaking the plastic retaining clips if possible. To release the clips push in at the tip.
5. You should now be able to pull the fuse box down a few inches, which is all you need.
6. Remove the screws holding the BCM to the fuse box, two screws on the right and one on the left.
7. Slide the BCM down and out to remove it from the back of the fuse box.

Reverse the procedure to put the new BCM in place. If you broke the retaining clips on the connectors you will need to use duct tape to hold them in place.

Check engine light reduce engine power and traction controll off.


It could be the APP sensors or the throttle body throttle position sensors . What DTC'S - diagnostic trouble codes . Need to test the electrical wiring , 5 volt reference voltage. Drive by Wire Function and diagnostics by Wells
REDUCED ENGINE POWER - mass airflow sensor has nothing to do with this problem .
Throttle Actuator Control (TAC)
Reduced Engine Power Mode When the PCM detects a condition with the TAC system, the PCM may enter a reduced engine power mode. Reduced engine power may cause one or more of the following conditions:
?€¢
Acceleration limiting--The control module will continue to use the accelerator pedal for throttle control; however, the vehicle acceleration is limited.


?€¢
Limited throttle mode--The control module will continue to use the accelerator pedal for throttle control; however, the maximum throttle opening is limited.


?€¢
Throttle default mode--The control module will turn off the throttle actuator motor and the throttle will return to the spring loaded default position.


?€¢
Forced idle mode--The control module will perform the following actions:


-
Limit engine speed to idle by positioning throttle position, or by controlling fuel and spark if throttle is turned off.


-
Ignore accelerator pedal input.


?€¢
Engine shutdown mode--The control module will disable fuel and de-energize the throttle actuator.

I have a Saturn 2001 4door s series the security light is on and won't start what can I do


Passlock
The passlock system is a vehicle theft deterrent system which deters drive-away vehicle theft by disabling engine operation if the ignition lock cylinder is not rotated with the proper mechanically cut key.
The passlock system is made up of an ignition switch assembly, passlock sensor, body control module (BCM), instrument panel cluster (IPC), and a powertrain control module (PCM).
The ignition switch contains a magnet mounted on the lock cylinder and a passlock sensor assembly which consists of security hall effect sensor, tamper hall effect sensor, and output resistors. A drill proof metal shield is also staked over the sensor housing.
The passlock sensor mounted to the ignition switch assembly is located inside the upper right side of the steering column. The passlock sensor contains two hall effect sensors: a tamper hall effect sensor and a security hall effect sensor. The tamper hall effect sensor is mounted on top of the security hall effect sensor. Should someone attempt to defeat the system by use of magnetic experimentation, the tamper hall effect sensor will activate first.
The BCM has the passlock controller integrated into it which controls the majority of the security systems logic. The BCM reads the data from the passlock sensor continuously. If the data is correct and has been received by the BCM within a specified time, the BCM will send a coded password to the PCM. The PCM will then allow the fuel injectors to operate.
The coded password for the security system is sent from the body control module to the PCM via the class 2 data link. If the password is correct and received within the specified time, the PCM will allow the fuel injectors to operate.
The IPC contains the security telltale. The security telltale has three modes of operation, OFF, FLASHING, and ON.
SECURITY TELLTALE will be off if:
?€¢
Ignition is in the OFF position


?€¢
Ignition is in the RUN, START, or ACC position and security system diagnostics have all PASSED

SECURITY TELLTALE will be on if:
?€¢
The BCM is performing a bulb check at vehicle start


?€¢
Security system diagnostics have not yet completed at vehicle start


?€¢
A security system diagnostic trouble code (DTC) is set in the BCM or PCM

SECURITY TELLTALE will be flashing if:
?€¢
The tamper hall effect sensor has been triggered


?€¢
Incorrect passlock sensor data to BCM for more than 5 seconds during vehicle start


?€¢
No passlock sensor data to the BCM for more than 5 seconds during vehicle start


?€¢
Incorrect password from the BCM to the PCM after 5 seconds during vehicle start

2001 saturn lost keys to it. Got it to crank cut right back off secrity lights on bought a brain box for it and got 2keys with it. Still want crank I need to know what to do t could the box be bad ..


No ,the box is probably not bad , but you need to have it programmed . The dealer is the only one that can do that ? The keys don't matter .

Sorry but you can't just replace parts , you need to know how the system works . You need to take this to a ASE certified repair facility that knows how it works .

P2104 - Throttle Actuator Control (TAC) System - Forced Idle Description: The TAC system is in the failure mode effects management (FMEM) mode of forced idle. Possible Causes:
  • Open or short in multiple accelerator pedal position (APP) sensor circuits.
  • Damaged APP sensor.
  • Damaged powertrain control module (PCM).
Diagnostic Aids: This DTC is an informational DTC and can be set in combination with a number of other DTCs which are causing the FMEM. Diagnose other DTCs first. Application Key On Engine Off Key On Engine Running Continuous Memory All

P2112 - Throttle Actuator Control (TAC) System - Stuck Closed. Description: This powertrain control module (PCM) fault status indicates the throttle plate is at a lower angle than commanded. Possible Causes:
  • Binding throttle body, stuck closed.
  • Damaged PCM.
Diagnostic Aids: Application Key On Engine Off Key On Engine Running Continuous Memory All GO to DV1 Are you familiar with electronic throttle control ? You have a dc electric motor on the throttle body an at the gas pedal there are APP pedal position sensors that send voltage signals to the PCM which in turn controls the electric motor opening an closing the throttle ! By what this P02112 states the throttle plate is binding , which means it could be bad or just needs to be cleaned ! You will need to disconnect the electrical connector an see if it is binding by pushing it with finger or thumb . which is ever easiest !

Where is the body control module


Fieros do not have a 'Body Control Module'. They have an ECM for the engine, V6s with cruise control have a module behind the carpet by gas pedal, 87-88s have a headlight motor control module behind the driver's side fender, and there is an Ignition Control Module in the distributor.
So take your pick of other modules, but sorry, no 'Body Control Module'. You must have gotten some bad info.

Car bogs down epc light comes on, then goes off car runs then normally, I replaced mass air flow, front and back 02 sensors, but continues to bog and epc light goes on and off


epc is short for electronic pedal control, the throttle is controlled by an electric motor and has two angle sensors in the throttle body. the pedal it self has two sensors as well, sometimes after a battery replacement or replacement of certain parts (ecm throttle body pedal controls) the control modules need to be reset or "relearned" to one another. the dealer or independent shop with correct softwear can do this, if problem persists possible bad throttle body pedal sensors or ecm (engine control module)
