FORD PATS (PASSIVE ANTI THEFT SYSTEM) INITIALIZATION WITH THE 2534 GLOBAL PROGRAMMER

Download There are five types of PATS implementations from Ford (A, B, C, D, E). Refer to Table 1 (page 11) to identify what type of PATS your vehicle is equipped with. PATS initialization is generally performed after programming. The A or D version of PATS does not store the key information in the PCM, therefore NO PATS KEY RELEARN IS REQUIRED after programming. The B or C versions of PATS store the key information within the PCM and MUST be transferred to the new PCM, or relearned on the vehicle after the new PCM is installed. The E version of PATS also stores the key information within the PCM, but CANNOT be transferred to the new PCM. This type MUST be relearned on the vehicle after the new PCM is installed. Note: If you are just updating the existing PCM calibration with an update calibration, you must select the MODULE REPROGRAMMING function (not Programmable Module Installation).… Read More

1997 Buick Riviera Camshaft Position (CMP) Sensor Performance

Download 1997 Buick Riviera | Aurora, Riviera (VIN G) Service Manual DTC P0341 Camshaft Position (CMP) Sensor Performance. Circuit Description The camshaft position PCM input is produced by the ignition control module. The ICM produces the camshaft position PCM input by filtering the camshaft position (CMP) sensor pulses when the engine is running and CKP sync pulses are also being received. The PCM uses the camshaft position PCM input pulses to initiate sequential fuel injection and to determine crankshaft position for the misfire diagnostic. The PCM constantly monitors the number of pulses on the camshaft position PCM input circuit and compares the number of camshaft position PCM input pulses to the number of 18X reference pulses and the number of 3X reference pulses being received. If the PCM receives an incorrect number of pulses on the camshaft position PCM input circuit, DTC P0341 will set and the PCM will initiate injector sequence without the camshaft position PCM input with a one in six chance that injector sequence is correct.… Read More
