Question about 2002 Ford Explorer
Check the battery voltage, should be more than 12.6 volts with engine off, and at least 14volts with running engine. If is less than 12.6 V then you have to replace the battery. A voltage less then 14V with running engine, indicates problems in charging system, and you might need a new alternator. If you have good battery and alternator, then you have to scan the codes, and turn the security light off. Sometimes disconnecting the battery for 30 minutes clears the code. Hope this might help.
