But from my reading in the service manual on system operation, I understand its operation to be something similar to the following.
PKE has basically four modes, they are:
Transmitter Not in range, receiver asleep. In this mode the PKE receiver does not have a transmitter in range and has gone into a power down state. The receiver has not seen a transmitter for 5 seconds, and is waiting for another transmitter.
Transmitter Not in range, receiver awake. In this mode, the PKE receiver does not have a transmitter in range but has not gone into power down state. This mode occurs when the transmitter has left the range, but the receiver has not timed out, due to a door reamining open, a key being in the ignition or if 10 seconds have not elapsed. The passive locking functions originate from this mode.
Transmitter In range, Key Not in ignition. This mode is reached when a tansmitter is brought into range while the ignition key is out of the ignition. If the passive mode has been enabled, the passive unlock features are accessed thrugh this mode. THe passenger door unlock feature and the hatch release feature are also accessive through this mode.
Transmitter In range, Key In ignition. This mode occurs when the PKE receiver has recognized a transmitter and the ignition key is inserted. When this mode occurs, passive locking and unlocking features are disabled. The motion sensor feature, which unlocks the doors will still work. Most of the incidental features (i.e., programming, diagnostics, and selection of all doors unlock or just passenger door unlock) are accessed from this state. (BTW I think this is a typo in the manual, I think they mean 'just driver's door unlock' because I'm only aware of both doors unlock or just driver's door unlock.) If the key is in the ignition switch, either with the ignition ON or OFF, the PKE system will disable all passive lock and unlock functions except for the key-in ignition unlock feature. If the key is in the ignition, the manual controls on the transmitter will be functional oonly when the ignition is OFF.
Ok now other aspects of the system are UTD Universal Theft Deterrent. PKE sends signals to arm and disarm UTD. The resistor in the key is part of the UTD.
In the last mode, second to last sentence discusses the 'key-in ignition unlock feature'. The only note in this section is that is says "A valid transmitter DOES NOT have to be in range." I understand that to mean that if one is or is not in range (sending out a signal) no matter, with the key in the ignition and door locked and shut they will auto unlock.
Unless the PKE system is malfunctioning, it should command the last know condition (unlock driver door or both doors) when a key is in the ignition and the doors are closed and locked. From what I'm reading it does not seem to have any relationship with passive mode or non-passive mode lock/unlock function. My understanding on the passive/non-passive mode is enabled or disabled by holding the door button down on the transmitter with the key out of the ignition.
A transmitter sends out a coded signal for 21 seconds after it is moved. As long as there is power to the vehicle the receiver listens constantly for a transmitter.
So I would think that just waiting and not allowing any movement in the vehicle for at least 21 seconds ensures the "hidden" transmitter is silent now.
Also something to note about bulb tests and when it doesn't illuminate. If the passive unlock/lock feature has been disabled, the PASSIVE KEYLESS ENTRY telltale lamp will NOT illuminate for bulb check upon ignition ON.
So if your passive mode is disabled, and you turn the key to ON to do a bulb test it won't illuminate. It must be in the enabled mode for this to test. I believe I remember reading earlier in the thread someone tested with a known good bulb and it still was not illuminating. So this may be a partial answer to your system diagnosis, in that your passive unlock/lock mode is disabled.
To resolve the functioning issues, the troubleshooting procedures need to be followed so that components and functionality can be isolated properly. I hope this helps, and does not imply an argument.
