Weird one - have you tried resetting the error and seeing if it comes back? If not, good. Temporary hiccup.
If it comes back, maybe source a used/no error SRS module and swap out with yours and see what happens. The codes are recorded in the SRS module so a good one will have no codes.

Alternatively, it might be corrosion in one of the wiring looms - if you can trace out the wires (and ohm them out) going through the door to the car, the problem might be in there too.

The SRS module is allegedly easy to swap with four bolts and 20 minutes to spare. Depending on how cheap they are to get, that could be worth a shot.
Good luck, and please post a comment if/when you find a solution to help others. :)

SOURCE: volvo v40 stalling when idling

If the car shakes and stalls at lights stop signs etc. I would check the egr ( exhaust recirculator valve) first this valve should open when in driving mode and close immediately when engine comes back to idle. to check this find the valve on the intake manifold ( looks like a mushroom) remove vaccuum line and plug hose drive the car and see if it fixes the problem. If it does get one from local parts store. Most brands such as standard are universal and come with baffles that must be installed. do not leave the valve disconnected the engine will "ping" when driving forcing you to buy higher octane gas. It is also illegal to remove this unit for emission reasons.

If you have SRS and "brake failure" it should be taken to a dealer. a shadetree mechanic will screw more up than he will fix in this case. trust me on this! you will pay a price, but will save you more $ and less headache in the longrun.

SOURCE: Volvo V40 heater does not work properly

First check if you have enough coolant in your car. If it's low, it might not reach your system. When the engine is off it should be just under MAX.

2006 GMC Envoy: I tested all of the fuses and all of them check out but my power locks, cabin lighting, dash panel lights, etc. aren't working.


Which fuse box ? Do you know what a DDM -is ? Driver door module . Do you have any idea what all is involved in making these thing's you have listed work ? A lot more then a fuse , there could be DTC'S - diagnostic trouble codes stored in the principal Control module ,the BCM , That could save a tech. valubale time in diagnoising this problem !
Door Lock System Components
The power door lock system consists of the following components:
• Driver Door Module (DDM)
• Passenger Door Module (PDM)
• Liftgate Module (LGM)
• Door lock relay
• Door unlock relay
• Body Control Module (BCM)
• Reversible door lock actuators in each of the doors
• LR/RR LOCKS 10A fuse (relay supply voltage)
• Door lock switches in driver and passenger doors (switches are integral components to the DDM and PDM)
Did you know there is a fuse box in the rear of the vehicle ?
Fuse Block - Rear
Beneath the left rear seat
The inside lights are also controlled by the BCM , and the fuse's are also located in the rear fuse box .
The body control module (BCM) directly sends a 5-volt reference voltage to the instrument panel (I/P) dimmer switch which is then adjusted based on the I/P dimmer switch position and returned as a low reference and a signal to the BCM. The BCM uses this signal to directly control the desired level of instrument panel illumination lamp intensity.
DTC Descriptor
This diagnostic procedure supports the following DTC:
DTC B2620 Display Dimming Pulse Width Modulation (PWM) Input Circuit. There are several DTC'S that can set !
DTC B3801 Passenger Compartment Lamp Request Circuit
DTC B2610 Passenger Compartment Dimming 1 Circuit plus others for power locks .

My right side passenger door does not lock automatically anymore. Is there a fuse that operates this.


no all is related to one fuse you can remove the door internal controls and decore and remove center lock motor plug and test two connectors with multimeter with set on 12v and then lock un lock door and check the reading of the multimeter if it read signal then all plugs and wires from central lock control unit to the door central lock unit is okay it this cae you have to replace the door central lock unit with the same if no signal is readed while you lock unlock the door then you have to check central control unit and all wire plus out of it to the door plug

2- you can remove central control unit from driver door and test it in passenger door (usually the same unit ) if it works with lock unlock its then the replaced unit is faulty and needs to be replaced if it not work then check plugs wires from central lock unit (usually found inside driver door ) to the central lock unit in passenger door

3- check signal for said door fro the output of central door unit if no signal then it mean that faulty central lock control unit

In some cases you may need to unlock the door but leave the key turned to the unlock position for a few seconds. Aside from that your RF receiver for the signal from the keyless could be at fault. Hope that helps.

Doorlocks dont work except from passenger side. mirrors dont work. windows dont work from anywhere


First, check all fuses to make sure that none are blown.

If the door lock switch works on the passenger side, then the drivers side door lock switch is probably faulty. Use a multi-meter to test the Drivers Side Door Lock Switch (Black and Pink/Light Green wires unlock the vehicle, and the Black and Pink/Yellow wires lock the vehicle)
If the switch is tested and found to be operating properly, you may have a faulty Body Security Module or Drivers Side Door Lock Actuator.

If neither of your Power Mirrors are working, you probably have a faulty Exterior Rear View Mirror Switch, Power Mirror Module, or blown Central Junction Box Fuse.

If none of your Power Windows are working, you probably have a faulty Accessory Delay Relay or a blown fuse in your Central Junction Box or a faulty Master Window Adjust Switch (all of the Power Window Switches feed through this Master Window Switch). If the Power Windows didn't stop working at the same time, you may have faulty Window Adjust Switches, or faulty Power Window Motors, this is very unlikely though. It would also be a good idea to inspect the wiring for any obvious damage.

The doors lock automatically on my daughter's '99 Cougar. This has happened to me when I left the keys in the ignition and closed the driver's door. After AAA came and unlocked the doors, I removed the...


shorted wiring in doors or shorted door lock actuator in door. A grounding of a wire makes them lock normally. SO, any bare wire touching metal will ground it and lock the doors.

Principles of Operations
The Door Switch Lock Function When a door lock switch is moved into the lock position or a door lock cylinder is rotated to the lock position, the door lock switch grounds the lock circuit input to the central security module (CSM). The CSM then provides 12 volts to one side of the door lock actuators contained in the door latch unit and simultaneously grounds the other side of the door lock actuators. This completes the door lock actuator circuit, causing the door lock actuators to rotate a cam assembly, which then locks the doors. The 12 volts that the CSM provides to the door lock actuators are provided to both door lock actuators from a single pin on the CSM electrical connector.
The Door Switch Unlock Function When a door lock switch is moved into the unlock position, the door lock switch grounds the unlock circuit input to the CSM. The CSM then provides 12 volts to the opposite side (relative to locking the door) of the door lock actuator(s) contained in the door latch unit and simultaneously grounds the other side of the door lock actuator(s). This completes the door lock actuator circuit, causing the door lock actuator(s) to rotate a cam assembly in the opposite direction, which the unlocks the door(s). The 12 volts which the CSM provides to the door lock actuator(s) are provided to each door lock actuator from the individual pins on the CSM electrical connector.
--------------------------------------------------------
CSM Self-Test The CSM has a self-test which can be entered into by using a diagnostic tool. This self-test will monitor the following CSM door lock inputs:
  • Unlock switch (DTC B1311)
  • Lock switch (DTC B1300)
  • Exterior lock switch (DTC B1309)
  • Exterior unlock switch (DTC B1341)
Before running the self-test, the following conditions must be met:
  • The ignition switch must be in position II
  • The driver and passenger doors must be unlocked
  • The driver and passenger doors must be opened
  • The hood and liftgate must be closed
  • The set/reset switch, and liftgate release switch are not actuated
It is important to note that all of the diagnostic trouble codes (DTCs), with the exception of B1551 and B1553 can be retrieved with the self-test. DTCs B1551, and B1553 are continuous and will only be retrieved if the liftgate release is operated prior to retrieving the continuous DTCs.
Inspection and Verification
  1. NOTE: Make sure that the battery is fully charged before starting electrical diagnosis.
    NOTE: Prior to carrying out the CSM Self-Test, make sure that both the driver and passenger doors are open.
    Verify the customer concern.
  1. Visually inspect for obvious signs of mechanical and electrical damage.


Visual Inspection Chart Mechanical Electrical
  • Binding latch mechanisms
  • Binding linkage
  • Misaligned door
  • Central junction box (CJB) fuse(s)
  • Wiring harness
  • Electrical connector(s)
  • Door lock switch(es)
  • Door lock actuator(s)


Module Controlled Functions
The central security module (CSM) covers the following functions:
  • Central door locking
  • Double door locking
  • Anti - theft alarm incorporating
    • forced entry
    • radio theft
  • Radio frequency remote control of
    • central door locking
    • panic alarm

For additional information, refer to Section 419-01A Anti - Theft - Active, Section 501-14A Handles, Locks, Latches and Mechanisms, and Section 501-14B Keyless Entry/Computer Operated Locks.

The CSM is in the passenger side kick panel I think.

Good luck

Driver's side door won't open in the cold


.
Power Door Lock Operation (Front Doors)
The front doors do not have traditional door lock actuators. They have electronically controlled door latches that will operate depending on the status of the door lock system. This status is determined by the front door modules and the last known state of the lock system. If the last known state is LOCK, the latches will not release when the door handles are operated. If the last known state is UNLOCK, the latches will release when the door handles are operated. The front doors are also equipped with red door lock status indicators. The front door modules will supply power and ground to the indicators to illuminate them when the lock system is in a virtual state of lock. The indicators will not continuously illuminate when the vehicle is locked. They will illuminate for approximately 5 seconds after a lock switch activation or after a door handle has been operated and the front door modules are in a virtual state of lock. For further information on the front door latches, refer to Power Door Latch Description and Operation .
I would assume they check for DTC'S - diagnostic trouble codes ?
DTC B3062 Front Door Key Lock Switch Circuit
• DTC B3067 Front Door Key Unlock Switch Circuit
DTC B3849 Exterior Door Handle Switch Circuit
The left front exterior door handle and right front exterior door handle switch signal circuits provide inputs to the driver door module (DDM) and passenger door module (PDM) when an exterior door handle switch is activated. These inputs allow the door module to detect a door open request. The door modules provide voltage to the door handle switches. If the door module detects that a ground is applied for greater than 30 seconds continuously, a DTC is set and the door module will ignore the door handle switch input.

REAR DOOR LOCK


you either have a faulty central locking motor or the wiring harness may be damaged.
Remove the door panel and check if you have a live feed to the central locking motor when you use the fob to lock or unlock. If you have power, then it will most likely be the motor that is at fault.
