The class 2 serial data circuit is used in order to communicate between the powertrain control module PCM and the vehicle theft deterrent VTD body control module BCM systems. When the Passlock portion of the VTD system has sensed the proper operation of the ignition switch and lock, or determined that the switch and lock have not been tampered with, the BCM transmits a password to the PCM.

Fuel delivery is enabled if this password matches the password stored in the modules memory. If a component in the theft deterrent system has been replaced, the modules need to relearn the password of the new components. If the relearn procedure was not performed, this DTC will set. The BCM remains in Fail Enable Mode, for the current and future ignition cycles, until the fault is corrected and a valid password is received, or until battery power is removed.

If the battery is disconnected or the codes are cleared, the vehicle will lose its Fail Enable status and will not start until the fault is corrected, the minute timer expires, and the PCM receives the correct fuel delivery password. The PCM records the operating conditions at the time the diagnostic fails. If a fault or tamper has been detected, the BCM will not forward the correct password to the PCM for a period of 10 minuteseven if the condition is corrected during that time period.

This timer can be monitored in the Passlock Data parameter of the scan tool. Once the time has elapsed, the BCM will determine if the condition is still present. The Passlock state and the auto learn timer can be viewed in the Passlock Data parameter of the scan tool.

These may cause an intermittent malfunction. This Procedure will take approximately minutes. In some vehicles, the Battery and Security light will blink for several seconds, and then shut off.

Then the Security light will then remain ON. This will take more than 5 mins. Once this entire procedure has been completed three times your vehicle will start on the fourth attempt. Note: Some vehicles perform the relearn in a different sequence.

The problem is caused by the variable cylinder management system switching on and off during light throttle conditions, at cruising speeds, or when driving on flat roads. The constant switching causes excessive oil consumption and the trouble codes appear when oil pressure drops to the point where it can no longer operate the VCM system. If the change in pressure is outside of the calibration the DTC will set.
