How to Deactivate Airbag system on Ford Ranger?

If you are replacing cruise control related parts or removing steering wheel or replacing clock spring etc etc.
Then in that cases,first the Airbag system needs to be deactivated

The procedure to do this is as follows :----

Here are the instructions for depowering and repowering the air bags.

NOTE :---The fuses listed are in the under dash fuse panel.

First read Deactivating procedure:--

Turn all vehicle accessories OFF.
Turn the ignition switch to OFF.
At the central junction box (CJB), located on the LEFT HAND end of the instrument panel, open the kick panel cover and remove the restraints control module (RCM) fuse F2.2 (10A) and F2.26 (10A) from the CJB. 

Turn the ignition ON and visually monitor the air bag indicator for at least 30 seconds. The air bag indicator will remain lit continuously (no flashing) if the correct RCM fuse has been removed. If the air bag indicator does not remain lit continuously, remove the correct RCM fuse before proceeding.
Turn the ignition OFF.

WARNING: To avoid accidental deployment and possible personal injury, the backup power supply must be depleted before repairing or replacing any front or side air bag supplemental restraint system (SRS) components and before servicing, replacing, adjusting or striking components near the front or side air bag sensors or RCM, such as doors, instrument panel, console, door latches, strikers, seats and hood latches.

To deplete the backup power supply energy, disconnect the battery ground cable and wait at least one minute. Be sure to disconnect auxiliary batteries and power supplies (if equipped).

Now go through the Re-powering Airbag activating procedure:

Make sure all restraint system diagnostic tool(s) that may have been installed during the repair have been removed from the vehicle and all SRS components are connected.
Turn the ignition switch from OFF to ON.
Install the RCM fuse F2.2 (10A) and F2.26 (10A) to the CJB and close the cover.

WARNING: Be sure that nobody is in the vehicle and that there is nothing blocking or set in front of any air bag module when the battery ground cable is connected.Connect the battery ground cable.
Prove out the supplemental restraint system (SRS) as follows:
Turn the ignition key from ON to OFF. Wait 10 seconds, then turn the key back to ON and visually monitor the air bag indicator with the air bag modules installed. The air bag indicator will light continuously for approximately six seconds and then turn off. If an air bag supplemental restraint system (SRS) fault is present, the air bag indicator will either:
- fail to light.
- remain lit continuously.
- flash.
The flashing might not occur until approximately 30 seconds after the ignition switch has been turned from the OFF to the ON position. This is the time required for the restraints control module (RCM) to complete the testing of the SRS. If the air bag indicator is inoperative and a SRS fault exists, a chime will sound in a pattern of five sets of five beeps. If this occurs, the air bag indicator and any SRS fault discovered must be diagnosed and repaired.
Clear all continuous DTCs from the restraints control module using a scan tool.
A scan tool is required for this procedure.
Its easily available at local auto part store.
You can either buy the tool or get it for rent.Many auto part store provide this tool for rent.
