Passlock Code - Range

RANGE: OPEN/SHORT/TAMPER/NUMERIC
The Passlock TM code displayed indicates the internal Passlock TM sensor resistance value. The Passlock TM Module determines if the Passlock TM code received is valid or invalid. The Passlock TM Module has 10 valid Passlock TM codes, an OPEN Passlock TM code, a TAMPER Passlock TM code, and a SHORT Passlock TM code. The scan tool will display any valid Passlock TM code as a numeric value. The value displayed on the scan tool should be within 1-10 (i.e.valid code 7), SHORT, TAMPER or OPEN.
