Question about 1996 Saab 900

Open Question

The receiver is not receiving the signal from the remote.

All locks operate when the drivers door is manually operated, but nothing happens when I use the remote. I have changed the battery in the fob for a new one. The light goes on in the fob when it is operated. Paul

Looking for location of the keyless remote control module on a 2010 Chevrolet Avalanche LT


Remote Control Door Lock Receiver (RCDLR)
The remote control door lock receiver (RCDLR) is a multifunction module that operates both the keyless entry system as well as the tire pressure monitoring (TPM) system. When an RF message is received from a keyless entry transmitter, the RCDLR interprets this signal and will request via serial data that the body control module (BCM) perform the specific function, i.e. door lock, door unlock, or vehicle locate. The RCDLR also sends messages out to the 2 Way Advanced Remote Start transmitter.

Remote Control Door Lock Receiver (RCDLR) (AP3 or AP8, without E52)
Top rear of the passenger compartment above the rear window


Remote Control Door Lock Receiver (RCDLR) (AP3 or AP8, with E52)
Left rear of the vehicle behind the D-pillar trim panel

Body Control Module (BCM)
On the lower left side of the I/P to the left of the steering column


Good luck !

My hatch won't release from the remote or the door switch. No solenoid sound at the hatch. How do I get it to open if it's not a bad fuse?


There are actually three relays , an there are controlled by the BCM - body control module !
When a door lock switch is activated in the lock or unlock position the BCM will receive a voltage signal on either the door lock switch lock or unlock signal circuits.
The BCM, upon receipt of a lock switch lock or unlock signal, will switch the appropriate lock relay control circuits to battery positive voltage. This will energize the appropriate lock or unlock relays. The relay will supply voltage to the door lock actuator lock or unlock control circuits to one side of the lock actuator. Since the opposing side of the lock actuators are connected to ground through the other lock actuator control circuit and the normally closed contacts of the lock or unlock relay, the doors and liftgate will then lock or unlock appropriately.
Three relays are used to operate the locks. DRV DR UNLCK relay, PASS DR UNLOCK and DR LCK relay. This is done to isolate the driver door lock actuator so it can be unlocked by itself using the keyless entry transmitter.
Rear Hatch/Gate Description and Operation
The liftgate can be opened by operating the switch on the instrument panel. Battery voltage is supplied to the liftgate actuator through the body control module (BCM). The BCM will pulse the liftgate actuator when a release input is received through the key fob, or the instrument panel switch.
Door/Lift gate Latch Assembly
  1. Install a 20-A fused jumper wire between the control terminal 3 and 12 volts. Install a jumper wire between the ground terminal 2 and ground.
  2. Verify the actuator turns on & off.
?‡'
If the function does not perform as specified, replace the applicable door latch.

I have a problem with opening car doors with remote for 1997 pontiac sunfire. I noticed that when you are in the car and you activate the open and close switch from drivers side the locks at the rear open...


Try this procedure...

KEY FOB PROGRAMMING INSTRUCTIONS
Transmitter Programming
No Tools Required
In the event that a transmitter is lost, program the old & the new transmitters into the memory of the remote control door lock receiver. Up to 4 transmitters may be programmed.


Important
Once the keyless entry receiver enters the programming/diagnostic mode, the programming of the first transmitter erases all previous transmitter programming information. You must then program all of the transmitters.

Program only 1 vehicle remote control door lock receiver at a time. If u program multiple receivers simultaneously, the same transmitter could possibly be programmed to more than 1 remote control door lock receiver.


Perform the following steps:

Sit in the vehicle driver is seat. (actually it’s much ezr from the front pass seat)
Remove the ignition key from the ignition lock cylinder.
Close all of the vehicle is doors.
Remove the MALL PGM fuse from the fuse panel. Refer to Electronic Diagnosis in Body & Chassis.
Turn the ignition lock cylinder to the ACC position.
Turn the ignition lock cylinder OFF, then back to ACC within 1 second.
Open & then close any vehicle door. You will hear a chime when the remote control door lock receiver enters the programming/diagnostic mode. If u do not hear a chime, start again at step 1.

Important
After 7 seconds, you may hear a chime confirming successful synchronization. After approximately 14 seconds, you will hear a chime confirming successful programming.


Press & hold the transmitter LOCK & UNLOCK buttons simultaneously for 14 seconds.
Repeat step 8 in order to program each additional transmitter.
Remove the ignition key from the ignition lock cylinder.
Install the MALL PGM fuse back into the fuse panel. Refer to Electrical Diagnosis in Body & Chassis.
Validate that all the transmitters that were programmed operate properly. Refer to Keyless Entry System Operation

Hope this help (remember comment and rated this).

My Volvo S60 Fuel flap won't lock or unlock,


The pin solenoid that activates the remote locking is not receiving any electrical signal, it must have been unhooked. This solenoid is right by the filler door, inside the boot. The alarm activates on electrical differences, such as dome light, boot light or filler door electrical demand when it is activated. Hence, the alarm wont trip off if door is opened manually from the outside.

I have a 98 GMC JIMMY. Remotes and Dome Lights stopped working. Car would start then immediately die. Took it to the dealer and they stated it was the Body Control Modual (BMC). Picked up the vehicle...


Keyless Entry System Circuit Description
The Power Door Locks/Remote Keyless Entry control system provides several functions. The driver operates the vehicle door locks and rear window release from outside the vehicle using a hand-held radio transmitter. The transmitter sends coded signals to the remote control door lock receiver. The remote control door lock receiver detects and decodes the signal from the transmitter. The remote control door lock receiver issues signals to the body control module (BCM) through a serial data link. The BCM actuates relays to lock and unlock the doors and liftgate. The BCM can also release the liftglass. The power door lock switches provide manual control of the door locks.


Transmitter Programming
Important: Different keyless entry systems are used on General Motors vehicles. The parts are not interchangeable even though the parts may appear to be similar. Observe the back of the transmitter in order to properly identify the system. On 1998 S/T pickups and utilities, use a transmitter identified with GM/UTA preceding the part number.
With the driver door closed, hold down the power unlock button on the door panel.
Turn the ignition switch to the ON position.
Turn the ignition switch to the OFF position.
Turn the ignition switch to the ON position.
Turn the ignition switch to the OFF position.
Release the power unlock button on the door panel.
The remote control door lock receiver will respond in the following manner in order to indicate that the receiver is in the programming mode:
6.1. Locking the doors
6.2. Unlocking the doors
Important: All extra transmitters must be programmed at this time. When a new transmitter is programmed, it will deactivate the old transmitters.
Hold down the lock and unlock buttons on the transmitter until the remote control door lock receiver will respond in the following manner:
7.1. Locking the doors.
7.2. Unlocking the doors.
Repeat step 7 for each additional transmitter.
Turn the ignition switch to the ON position in order to exit the transmitter programming mode.

I think you need to reprogram the module, you deleted the horn chirp and light flash confirmation. he dealer can reprogram for you.

Principles of Operation
Power Door Locks
The generic electronic module (GEM) controls the power door lock and keyless entry system. Lock and unlock operation is achieved through the use of internal relays in the GEM. The relays are all door lock, all door unlock and driver door unlock. The normal path of the relays is to ground.
Pressing the door lock control switch to lock or unlock sends a ground signal to the GEM. The same GEM pin is used for unlock and lock input. The unlock signal is a direct connection to ground. The lock signal is altered by an internal resistor in the door lock control switch. This varied resistance identifies lock or unlock command to the GEM.
The door locks can also be controlled by the door key cylinder switches. For the liftgate door lock switch, turning the key to lock or unlock sends a ground signal to the GEM. The GEM will then ground the all door lock or all door unlock relay supplying voltage to the actuators. Turning the driver door key cylinder to the lock position sends a ground signal to the GEM. The GEM will then ground the all door lock relay supplying voltage to the actuators. Turning the driver door key cylinder to unlock sends a ground signal to GEM. The GEM will ground the driver door unlock relay and supply voltage to only the driver door actuator. If a second unlock ground is received within three seconds of the first, the GEM will ground the all door unlock relay supplying voltage to the passenger door actuators (if 2-stage unlock is equipped).
Keyless Entry
The keyless entry remote transmitter sends a signal that is received by the GEM internal antenna. Depending on the signal received, the GEM module will ground the appropriate internal relay and lock all doors or unlock the driver door. If the unlock signal is received again within three seconds of the first unlock, the GEM will ground the internal all door unlock relay unlocking all doors. The lock and unlock relay output to the actuators is controlled by the GEM, the same as power door lock operation from the control switch.
If the signal received is for the panic button, the GEM will cycle ground to the park lamp relay coil and horn relay coil. The park lamps and horn will continue to cycle until the panic button is pressed again or the ignition switch is turned to the RUN position, or after the timer expires.

Honda Element doors auto lock when keys in ignition.how to stop?


Actually, some other Honda models have a similar function, actuated by a combination of drive gear and road speed, but no Honda Element was ever factory equipped to automatically lock the doors when running. Its's a feature provided by some aftermarket keyless entry and/or security systems.
The Honda Elements' normal operation re-locks the doors if they are remotely unlocked, but a door isn't physically opened within 15-30 seconds. This is only supposed to happen when the keyless remote receiver signals the multiplex control unit to open the drivers door.

Open the drivers' window, take the battery out of the remote control fob, and see if the problem persists. If so, unplug the connector of keyless receiver module., and test again. If there's not a good electrical connection on all 4 pins of the KRU, or if the KRU is bad, that could cause your problem. Alsocheck G501. .
