Voltage at Pin 14 should be equal to battery voltage. If the voltage at Pin 14 drops to less than 8 volts, the air bag diagnostic monitor will flash out on the air bag indicator a DTC 12. If the voltage at Pin 14 drops to less than 5 volts, the DTC 12 will also be stored in memory. Should the loss of battery voltage at Pin 14 be intermittent or repaired, the air bag diagnostic monitor will flash out a DTC 52 (or higher priority code if one exists) on the next ignition switch cycle.Low voltage at air bag diagnostic monitor Pin 14 can be caused by:<ul> <li data-xf-list-type="ul"> An open in the battery circuit that would prevent battery voltage from reaching air bag diagnostic monitor Pin 14.</li> <li data-xf-list-type="ul"> A short to ground on the battery feed circuit between the fuse and Pin 13 or Pin 14 of the air bag diagnostic monitor.</li> <li data-xf-list-type="ul"> A concern in the charging system causing battery voltage to drop below 8 volts.</li> </ul></blockquote>
