If the module detects that the sensor input is less than 3.4 +/- 0.6% of the Seat Weight Sensor 5 Volt circuit voltage. This Diagnostic Trouble Code (DTC) will also set if the Seat Weight Sensor 5 Volt circuit is shorted to ground. However, this condition would prevent communication with the Occupant Classification Module (OCM) and cause a Lost Communication With OCM DTC to set in other modules. Also, this DTC will remain active after the condition that set this fault is no longer present. This condition is referred to as latching the DTC for the ignition cycle. Cycling the ignition key will change the status from active to stored if the condition that set the fault is no longer present.
