Two things. You have a power wire to the cluster that is shorted to ground or the cluster itself is shorted.

SOURCE: Instrument cluster failure causes fuse #29 to blow.

ok it could be quite simple
lets look at wrong size fuse
example 15 and you need a 25 fuse
also if you did any work on vehicle its quite possible that you grounded something out wrong retrace your work and fix accordingly
bad cluster relay is another problem that would cause these problems

The 2002 F-250 PStroke 4x4 had the instument lamps poping the fuse intermittently .
Turned out to be a wire getting pinched btween the emergency brake lever and the release stop .
Had to remove the keft kick panel and there was a yellow wire coming from the lower harness up toward the dash . the wire was pinched /hung up in the emergency brake mechanism . Good Luck

SECTION 419-01: Anti-Theft - PATS 2002 F-150 Workshop Manual
DESCRIPTION AND OPERATION Anti-Theft -PATS The passive anti-theft system (PATS) contains the following components:
  • theft indicator
  • encoded ignition key
  • transceiver module
  • instrument cluster
  • powertrain control module (PCM)
  • standard corporate protocol (SCP) communication network
The PATS uses radio frequency identification technology to deter a driveaway theft. Passive means that it does not require any activity from the user. This system is known as SecuriLock® in North America, Safeguard® in the U.K. and PATS in continental Europe. This information can be found in owners literature.
The PATS uses a specially encoded ignition key. Each encoded ignition key contains a permanently installed electronic device called a transponder. Each transponder contains a unique electronic identification code, with over 72 million billion combinations.
Each encoded ignition key must be programmed into the vehicle's instrument cluster (the instrument cluster is also known as a hybrid electronic cluster [HEC]), before it can be used to start the engine. There are special diagnostic procedures outlined in the workshop manual that must be carried out if new encoded ignition keys are to be installed.
The encoded key is larger than a traditional ignition key. The key does not require batteries and should last the life of the vehicle.
The transceiver module communicates with the encoded ignition key. This module is located behind the steering column shroud and contains an antenna connected to a small electronics module. During each vehicle start sequence, the transceiver module reads the encoded ignition key identification code and sends the data to the instrument cluster.
The control functions are contained in the instrument cluster. This module carries out all of the PATS functions such as receiving the identification code from the encoded ignition key and controlling engine enable. The instrument cluster initiates the key interrogation sequence when the vehicle ignition switch is turned to RUN or START.
The PATS uses the PCM to enable or disable the engine. The instrument cluster communicates with the PCM over the SCP network in order to enable engine operation. The instrument cluster and the PCM use sophisticated messages in order to prevent a theft. The instrument cluster and the PCM share security data (when first installed together) that makes them a matched pair. After this security data sharing, these modules will not function in other vehicles. The shared PCM ID is remembered even if the battery is disconnected. The instrument cluster also stores the vehicle's key identification code even if the battery is disconnected. There are special diagnostic procedures outlined in this workshop manual that may be carried out if either a new instrument cluster or PCM needs to be installed.
All elements of PATS must be functional before the engine is allowed to start. If any of the components are not working correctly, the vehicle will not start.
PATS uses a visual theft indicator. This indicator will prove out for three seconds when the ignition switch is turned to RUN or START under normal operation. If there is a PATS problem, this indicator will either flash rapidly or glow steadily (for more than three seconds) when the ignition switch is turned to RUN or START. PATS also "blips" the theft indicator every two seconds at ignition OFF to act as a visual theft deterrent.
The PATS is not compatible with aftermarket remote start systems, which allow the vehicle to be started from outside the vehicle. These systems may reduce the vehicle security level, and also may cause no-start issues. Remote start systems must be removed before investigation of PATS-related no-start issues.

The instrument cluster and the PCM share security data (when first installed together) that makes them a matched pair. After this security data sharing, these modules will not function in other vehicles. The shared PCM ID is remembered even if the battery is disconnected. The instrument cluster also stores the vehicle's key identification code even if the battery is disconnected. There are special diagnostic procedures outlined in this workshop manual that may be carried out if either a new instrument cluster or PCM needs to be installed.
All elements of PATS must be functional before the engine is allowed to start. If any of the components are not working correctly, the vehicle will not start.
PATS uses a visual theft indicator. This indicator will prove out for three seconds when the ignition switch is turned to RUN or START under normal operation. If there is a PATS problem, this indicator will either flash rapidly or glow steadily (for more than three seconds) when the ignition switch is turned to RUN or START. PATS also "blips" the theft indicator every two seconds at ignition OFF to act as a visual theft deterrent.
The PATS is not compatible with aftermarket remote start systems, which allow the vehicle to be started from outside the vehicle. These systems may reduce the vehicle security level, and also may cause no-start issues. Remote start systems must be removed before investigation of PATS-related no-start issues.

  • The anti-theft indicator is always/never on — no three-second theft indicator prove-out
  • Instrument cluster.
  • Theft indicator.
  • GO to Pinpoint Test B .
  • The vehicle does not start — theft indicator proves out for three seconds as normal
  • Less than two keys programmed to the system.
  • Transceiver not connected/defective.
  • Circuitry.
  • Transceiver internal antenna damaged.
  • NON-PATS key, damaged key or no code received.
  • Partial key read of PATS key.
  • Unprogrammed PATS key.
  • PERFORM instrument cluster on-demand self-test. RETRIEVE DTCs. If DTCs are present, GO to Instrument Cluster Diagnostics Trouble Code (DTC) Index. If no DTCs are retrieved, CHECK for other possible no-start causes.
  • No PCM ID stored in PATS.
  • PATS/PCM ID do not match.
  • Problem with SCP link.
  • CLEAR the stored DTCs. CYCLE the ignition key from off to run. RETRIEVE continuous DTCs. If DTCs are present, GO to Instrument Cluster Diagnostics Trouble Code (DTC) Index. If no DTCs are retrieved, CHECK for other possible causes.
  • The alarm system does not operate properly — the vehicle starts but flashes a fault code on theft indicator at key on
  • Incorrect PCM calibration.
  • GO to Pinpoint Test C .

--- Key Programming —Program a Key Using Two Programmed Keys NOTE: This procedure only works if two or more programmed ignition keys are available and it is desired to program additional key(s). If two keys are not available, follow the procedure in Key Programming—Erase All Key Codes and Program Two Keys .
NOTE: PID SPARE_KY must be enabled for this procedure to operate. If this Parameter Identification (PID) Index is not enabled, follow the security access procedure and select Spare Key Programming Switch: Enabled.
NOTE: If the programming procedure is successful, the new key(s) will start the vehicle and the THEFT INDICATOR will illuminate for approximately three seconds.
NOTE: If the programming procedure is not successful, the new key(s) will not start the vehicle and the THEFT INDICATOR will flash. If the programming procedure was not successful, repeat the key programming procedure from Step 1. If the failure repeats, check Circuit 729 (RD/WH) (hot at all times) in instrument cluster for proper battery voltage. Repair the circuit if voltage is not present. For additional information, refer to Diagnosis and Testing to review diagnostic trouble codes (DTCs) and perform pinpoint tests as required.
NOTE: A maximum of eight ignition keys can be programmed to a passive anti-theft system (PATS) equipped vehicle. Use PID NUMKEYS to determine how many keys are programmed to the vehicle.
NOTE: If the steps are not performed as outlined, the programming procedure will end.
NOTE: Ignition keys must have correct mechanical key cut for the vehicle and must be a PATS encoded key.
  1. Insert the first programmed ignition key into the ignition lock cylinder and turn the ignition switch from OFF to RUN (maintain the ignition switch in RUN for one second).
  1. Turn the ignition switch to OFF and remove the first key from the ignition lock cylinder.
  1. Within five seconds of turning the ignition switch to OFF, insert the second programmed ignition key into the ignition lock cylinder and turn the ignition switch from OFF to RUN (maintain the ignition switch in RUN for one second).
  1. Turn the ignition switch to OFF and remove the second key from the ignition lock cylinder.
  1. Within 10 seconds of turning the ignition lock cylinder to OFF, insert the unprogrammed ignition key (new key) into the ignition lock cylinder and turn the ignition switch from OFF to RUN (maintain the ignition switch in RUN for 1 seconds

Is there any way eliminate the anti-theft system on my 1999 windstar cause mine is malfunctioning and not allowing it to run (start). How many parts and connectors make up the system,anyways?


Anti-Theft —Passive The passive anti-theft system (PATS) contains the following components:

  • theft indicator
  • encoded ignition key
  • transceiver module
  • instrument cluster
  • powertrain control module (PCM)
  • standard corporate protocol (SCP) communication network
  • starter relay
The PATS uses radio frequency identification technology to deter a driveaway theft. Passive means that it does not require any activity from the user. This system is known as SecuriLock® in North America, Safeguard® in the U.K. and PATS in continental Europe. This information can be found in customer literature such as the Owners Guide.
The PATS uses a specially encoded ignition key. Each encoded ignition key contains a permanently installed electronic device called a transponder. Each transponder contains a unique electronic identification code, with over 72 million billion combinations.
Each encoded ignition key must be programmed into the vehicle's instrument cluster before it can be used to start the engine. There are special diagnostic procedures outlined in the manual that must be performed if the encoded ignition keys need to be replaced.
The encoded key is larger than a traditional ignition key. The key does not require batteries and should last the life of the vehicle.
The transceiver module communicates with the encoded ignition key. This module is located behind the steering column shroud and contains an antenna connected to a small electronics module. During each vehicle start sequence, the transceiver module reads the encoded ignition key identification code and sends the data to the instrument cluster.
The control functions are contained in the instrument cluster. This module performs all of the PATS functions such as receiving the identification code from the encoded ignition key and controlling the engine enable. The instrument cluster initiates the key interrogation sequence when the vehicle ignition switch is turned to RUN or START.
The PATS uses the PCM to enable or disable the engine. The instrument cluster communicates with the PCM over the SCP communication network in order to enable engine operation. The instrument cluster and the PCM use sophisticated messages in order to prevent a theft. The instrument cluster and the PCM share security data when first installed together that makes them a matched pair. After this security data sharing, these modules will not function in other vehicles. The shared PCM ID is remembered even if the battery is disconnected. The instrument cluster also stores the vehicle's key identification code even if the battery is disconnected. There are special diagnostic procedures outlined in this workshop manual that may be performed if either the instrument cluster or the PCM needs replacement.
All elements of PATS must be functional before the engine is allowed to start. If any of the components are not working properly, the vehicle will not start.
PATS uses a visual theft indicator. This indicator will prove out for three seconds when the ignition switch is turned to RUN or START under normal operation. If there is a PATS problem, this indicator will either flash rapidly or glow steadily (for more than three seconds) when the ignition switch is turned to RUN or START. PATS also "blips" the theft indicator every two seconds at ignition OFF to act as a visual theft deterrent.
PATS differs from perimeter anti-theft systems in that PATS enables and disables the engine from starting. If equipped, the perimeter anti-theft system protects the perimeter of the vehicle (doors, hood and trunk) and sounds an alarm.
PATS also disables the starter motor in addition to the PCM disabling the engine. When PATS disables the vehicle, it will neither crank nor start. If the instrument cluster is removed from the vehicle, the engine will not crank.
The starter relay is used as an additional means of disabling the vehicle engine. The starter relay is disabled when the PATS cannot read a valid encoded ignition key at ignition ON. The PATS will not store a diagnostic trouble code (DTC) or flash the theft indicator if a valid encoded ignition key is read but a fault occurs in the starter relay circuit.
The PATS is not compatible with after market remote start system, which allow the vehicle to be started from outside the vehicle. These systems may reduce the vehicle security level, and also may cause no-start issues. Remote start systems must be removed before investigation of PATS-related no start issues.
