2001 Mercury Villager Air Bag Parts Q&A

• Q: How to arm and disarm the air bag system on 2001 Mercury Villager?

  A: System proofing commences when you switch from off to run with the ignition while checking the air bag indicator through the installed air bag modules and safety belt pretensioners or restraint system diagnostic tools. Visual observations of symptoms during checks should result in analysis of the air bag supplemental restraint system concerns through the symptom chart if the system does not produce diagnostic trouble codes. Diagnostic trouble codes become available when checking fault codes through the air bag warning indicator located in the instrument cluster. Diagnostic testing takes place through two modes which users can select through sending signals from the LH front door courtesy lamp switch and ignition switch. The warning indicator for the air bag system will activate for seven seconds under user mode when you turn the ignition switch to on or start position yet it will extinguish when the system operates without issues. When a fault appears it will make the indicator visible for seven seconds before starting an ongoing flashing sequence. The continuous air bag warning indicator pinpoint test should be run when the air bag module shows illumination or the air bag diagnostic monitor detects a fault during the on state of the ignition. An entry into diagnosis mode requires selecting the ignition switch on position while pressing the LH front door courtesy lamp switch more than five times within seven seconds. The air bag indicator shows current fault data through specific indicator lighting sequences which begin with two seconds of darkness and proceed to two-second illumination followed by one-second darkness and two additional seconds darkness. The air bag indicator emits succession of brief flashes during fault code retrieval before flashing the start signal which plays repeatedly until the ignition becomes off or the user activates the air bag diagnostic monitor.
