F 150 supercrew lariet 2001 lost instrument lights, brake lights

Do you know anything about automotive electronic's ? Control modules ?
Vehicle Security Module
The vehicle security module receives inputs from the following:

• Door ajar switches
• Keyless entry keypad
• Ignition switch
• Remote keyless entry (RKE) transmitter

The vehicle security module uses these inputs to control an output signal to the instrument cluster which controls the battery saver relay and interior lamp relay. The battery saver relay and the interior lamp relay are internal to the instrument cluster, and are not replaceable. There could be a faulty switch input to the I/C - insturment cluster , causing the vehicle security module to activate the lock's an light's .
Interior Lighting Systems
The instrument cluster grounds the battery saver relay and interior lamp relay coils when any door ajar switch is opened, or the interior lamp (headlamp) switch is closed. The interior lamp relay then supplies voltage to the interior lamp circuit. Vehicle speed must be less than 24 km/h (15 mph) for the instrument cluster to ground the interior lamp relay. The interior lamps remain illuminated for up to 25 seconds after all doors are closed unless the instrument cluster receives an input from any of the following:

• voltage from the ignition switch.
• a vehicle speed signal.
• input from the keyless entry keypad through the vehicle security module.
• input from the RKE transmitter unlock or panic switch through
• the vehicle security module.

Do you know what DTC'S - diagnostic trouble codes are ?
Could have DTC'S stored in the following Modules

Door ajar switch problem more then likely or wiring issue . The BCM - body control module won't turn off interior light , let door lock because it think's the door is open . The door ajar switch is a input to the BCM .

The first thing would be to have it checked for DTC'S - diagnostic trouble codes . Also check with an enhanced scan tool to see if the BCM shows ajar switch data (open or closed ? Do you know about body electronics ?

Is your 'door ajar' or 'dome light' staying on? Forum members suggest various methods that they fixed their issue. The methods include:

• Adjusting the dimmer

• Spraying the switch with a lubricant

• Replacing the switch

• Replacing the relay

The door switch doesn't go to the dome lights , the switch (door ajar switch ) is an input to the SMJ - smart junction box or body control module take your pick .
Principles of Operation
When the SJB detects a request for lighting, it turns on the interior lamps by supplying power to the lamps. The request for lighting can be an open door signal from a door ajar switch, an interior lighting on command from the instrument panel dimmer switch or an unlock command from a remote keyless entry (RKE) transmitter.
The door ajar switches are hard-wired directly to the SJB. The 2 door ajar switches are normally closed when the doors are closed. The decklid ajar switch is normally closed when the decklid is closed. All door ajar switches receive voltage from the SJB and each has its own ground circuit.
The instrument panel dimmer switch receives a ground signal from the SJB. The instrument panel dimmer switch provides variable resistance for backlighting the instrument cluster and a toggle ON/OFF function for the interior lights.
The RKE receiver is contained inside the SJB. When the SJB receives an unlock request from an RKE transmitter, it unlocks the doors and turns on the interior lamps. There could be DTC'S diagnostic trouble codes stored in the SJB ! You can not access these codes with a OBD2 code reader , need a factory scan tool .

B2550 Dome Lamp Output Circuit Short to Ground Go To Pinpoint Test A . B2554 Dome Lamp Output Circuit Failure Go To Pinpoint Test D . Do you know B-codes -body control .
Your best bet is to take to a ASE certified repair facility or a Ford dealer .

Is the door ajar light in the cluster illuminated ?

Could be the door ajar switch ( part of the door latch ) is gummed up, and needs to be WD-40 sprayed into it, and close open the doors a few times, and repeat.

The autolock uses the same input, to know to lock the doors when you press the brake pedal while moving.

SOUND LIKE THE INTERIOR LIGHTS RELAY GOING BAD.

spray the door latch with WD - 40 on both doors then open and close multiple times. Sometimes they get stuck ond this help if they free up once a month should keep it away

The door switch is stuck on or the wire is shorted to ground.

Don't know what to do with the adhesive except to carefully remove with a long screwdriver, putty knife, etc. However, before you do that you should remove the screws in the door handle crevice. The two lower screws seem to come loose on their own so I replaced with one size larger stainless. The upper screws by the door handle are critical to remove the panel AND to secure it...

This is the problem with door switch on the car , you need to change the door switch in the car..


Good luck...
