Deville troubleshooting flow chart for b0041 code on a 2000 deville

Take your vehicle to a qualified repair shop as from your post you don't have a clue . And you never ever remove a battery cable while the vehicle is running . http://www.troubleshooters.com/dont_disconnect_battery.htm

DTC B0041 will set when one of the following conditions occurs:
- The SDM detects the LF side impact module deployment loop resistance is greater than 4.8 ohms for 500 milliseconds.
- The SDM detects the voltage at LF side impact module high control is less than 2.4 volts and LF side impact module deployment loop resistance is 6 ohms or greater for 500 milliseconds. it will continue to reset till the fault is repaired.

Code 446 means the evap system is not working correctly. You would need to find the actual troubleshooting chart for the code and work thru it to find the problem.
The evap system is how the computer vents the gas tank to the vapor canister.

• B0041

CIRCUIT DESCRIPTION
The inflatable restraint side impact module-LF deployment loop consists of the inflatable restraint side impact module-LF, the inflatable restraint side impact module wiring harness, and the side impact module-LF high and low circuits. A shorting bar used within the side impact module-LF connector shorts together the side impact module-LF high and low circuits when the connector is disconnected. This helps to prevent unwanted deployment of the inflator module during servicing. During a side or frontal crash of sufficient force the inflatable restraint Sensing and Diagnostic Module (SDM) allows current to flow through the deployment loop in order to deploy the side impact module-LF. When the ignition is turned ON, the SDM performs continuous diagnostic tests on the deployment loops to check for proper circuit continuity and for shorts to ground or voltage. If a malfunction is detected, a Diagnostic Trouble Code (DTC) will be stored in memory.

CONDITIONS FOR RUNNING THE DTC
Ignition 1 voltage is within the normal operating voltage range.

CONDITIONS FOR SETTING THE DTC

• DTC B0040 will set when the side impact module-LF deployment loop resistance is less than 1.3 ohms for 500 milliseconds .
• DTC B0041 will set when one of the following conditions occurs:
• Side impact module-LF high circuit is less than 2.4 volts and the side impact module-LF deployment loop is more than 6 ohms for 500 milliseconds .
• Side impact module-LF deployment loop resistance is more than 4.8 ohms for 500 milliseconds .
• DTC B0045 will set when one of the following conditions occur:
• Side impact module-LF high and/or low circuits is short to ground or short to voltage for 500 milliseconds .
• Side impact module-LF high circuit is less than 2.4 volts and side impact module-LF deployment loop resistance is less than 6 ohms for 500 milliseconds .

ACTION TAKEN WHEN THE DTC SETS
The SDM commands the AIR BAG indicator ON via Class 2 serial data.

CONDITIONS FOR CLEARING THE DTC

• The condition responsible for setting the DTC no longer exists and the scan tool Clear DTCs function is used.
• A history DTC will clear once 255 malfunction free ignition cycles have occurred.

DIAGNOSTIC AIDS
The following are possible causes of the malfunction:

• A short between the side impact module-LF high and low circuits
• An open or a high resistance in the side impact module-LF high or low circuits
• A short to ground or a short to voltage in the side impact module-LF high or low circuits
• The side impact module-LF connector
• The SDM connector
• A malfunctioning side impact module-LF
• A malfunctioning SDM

For Isuzy KB250 D in South Africa it is for the right hand driver pretensioner. Connects also at right front kick panel.

if you could be so kind as to give me the code..........I can give youa flow chart on what to check okay?

Take a look at aboutautomobile.com and click on the DTC section on the right hand side.. You can type your codes in and it will give you a description of each of them. Help this helps
