Antitheft and Alarm Systems

PATS Fault Codes

For the various PATS modes/faults listed in the table, the IC will store a DTC and indicate this to the customer during the detection period defined in the 'when logged' column, by illuminating the indicator as described for 60 seconds and then flashing the LED 10 times as appropriate. The indication will stop immediately the ignition is turned to off any time during the fault indication sequence. Up to 4 DTC's could be stored per key read (1 - !0 read attempts). No DTC's will be stored until all retry attempts are complete. Only the highest priority fault code will be flashed.

The PATS LED will be commanded on as shown under 'indication'. Normal PATS operations are complete within 400 ms of the ignition switch transition from off to run or start, worst case for ECM communication problems will be less than 2 seconds. If PATS is not complete during the 2 seconds the ECM will terminate PATS and await the next ignition run/start event. PATS faults will be indicated via the LED as soon as possible and will terminate the LED prove out. At key off all previous flashing will cease and the perimeter anti theft system will control the LED when the vehicle is locked and armed.







Following part replacement the following codes maybe applicable, these are not normal customer mode fault codes.







1. If an obvious cause for an observed or reported concern is found, correct the cause (if possible) before proceeding to the next step.
2. If the cause is not visually evident, verify the symptom and refer to the Jaguar Approved Diagnostic System.
