PASSLOCK Code

Range: OPEN/SHORT/TAMPER/NUMERIC
The PASSLOCK (TM) code displayed indicates the internal PASSLOCK (TM) sensor resistance value. The EVO/PASSLOCK (TM) Module determines if the PASSLOCK (TM) code received is valid or invalid. The EVO/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.
