System Operation
PASS-Key(R) CCM Inputs/OutputsThe CCM monitors the following as inputs affecting PASS-Key(R):
^ PASS-Key(R) input.
^ PASS-Key(R) return.
The CCM controls the following outputs for PASS-Key(R):
^ Theft deterrent relay.
^ "SECURITY" lamp.
^ Fuel enable (FEDS).
PASS-Key(R) Time-Out
When it has detected an invalid key, the PASS-Key(R) system disables cranking and fuel enable for a time-out period of approximately three minutes. If a key is inserted or the ignition is turned "ON" before the three minute time-out is complete, the timer will reset to three minutes. Disconnecting the battery or pulling fuses will not disable the time-out; the CCM stores the PASS-Key(R) state in EEPROM, and will restart the three minute timer when the battery is reconnected. Even if the proper resistance key is inserted during the time-out the vehicle will not start until the total time period has expired.
