Intermittent Loss Of Communication with several U-Codes and possible symptoms. Most common codes are the U1300, U1301 and U1305, U1016, U1064, U1096, U1169, U1161and U1162. Symptoms are one or all of the following; ABS Light On, Security Light On, Multiple Indicators On in the IPC, Heated Seats inoperative, Drivers and/or Passengers Door Window(s), Lock(s) and Mirror(s) are Inoperative. This concern can be intermittent and at times difficult to diagnosis yet communication is not always lost with the Tech 2. This concern when present, can be cleared by cycling the ignition to the "OFF" position, pause for a moment, then restart the vehicle. This could be the result of a module software concern and only applies to vehicles equipped with Memory seats (AAB), Heated seats (KA1), Electric Pedals (JF4) or a combination of them<a href=""http://service.gm.com/servlets/#ss2-1766589
]

An updated calibration was released for this concern. This calibration only applies to vehicles equipped with Memory seats (AAB), Heated seats (KA1), Electric Pedals (JF4) or a combination of them. The software was released on Monday February 20th 2006 through "TIS-2-WEB". It will be necessary to reprogram the Drivers Door Module (DDM), Passenger Door Module (PDM) and Drivers Seat Module (DSM).
1st - Reprogram the Drivers Door Module (DDM). Use SPS programing procedures and select the calibration that states
New software to address intermittent loss of power mirror, power window, and heated seat functionality which may be temporarily corrected by cycling the ignition".
2nd - Reprogram the Passenger Door Module (PDM). Use SPS programing procedures and select the calibration that states
New software to address intermittent loss of power mirror, power window
3rd - Reprogram the Drivers Seat Module (DSM). Use SPS programing procedures and select the calibration that states...
"New software to address DSM no communication issue during factory testing
Note: Prior to programming the Drivers Seat Module, make sure the LGM/DSM fuse is installed. This will only be a concern if TIS had a message advising to remove LGM/DSM fuse for programming the Drivers or Passengers door module.
If there are programming concerns, the TIS version numbers are listed below. Verify your TIS version numbers as necessary
TIS 2000

Please follow this diagnostic or repair process thoroughly and complete each step. If the condition exhibited is resolved without completing every step, the remaining steps do not need to be performed

GM bulletins are intended for use by professional technicians, NOT a "do-it-yourselfer". They are written to inform these technicians of conditions that may occur on some vehicles, or to provide information that could assist in the proper service of a vehicle. Properly trained technicians have the equipment, tools, safety instructions, and know-how to do a job properly and safely. If a condition is described, DO NOT assume that the bulletin applies to your vehicle, or that your vehicle will have that condition. See your GM dealer for information on whether your vehicle may benefit from the information
mechanic110 : Basically the vehicle control module needs to be updated by a GM dealer or an independant shop that has the capabilities of doing this.
It appears to be a technical issue but not a recall.

2002 Jeep Liberty heater works, but defroster blows cold air


on all cars made
(you can read the FSM at any time and see exact way and tests)
1: damper stuck or its actuator bad. ( 3 kinds uses on all cars)
2 ;controls to damper actuator bad.
3: wires between both faulty.

3 types are motor, vacuum servo and cable.
you have 2 of the 3.
the blend is a motor actuator
the recric is vacuum servo
the motor types are very hard to test, read the FSM.

ill post the calibration

quote

Use this procedure to ensure that the A/C-heater control is correctly calibrated to the blend door actuator. If the calibration is not correct, the heating-A/C system may experience a condition where full heating or cooling capabilities cannot be obtained.
Manual calibration of the A/C-heater control should be performed if the blend door actuator is not functioning properly, or if the temperature of the conditioned air is too warm with the temperature control in the full cold position or too cool with the temperature control in the full hot position.
NOTE This calibration procedure can only be started within the first ten seconds after the ignition switch has been turned from the OFF position to the ON position. Make sure that the battery is fully charged prior to beginning the calibration procedure. NOTE The length of the pause made at each end of the temperature control rotation (sweep) is important. 5 seconds) or too long (greater than 1.5 seconds).
  1. With the ignition switch in the OFF position, move the temperature control to its middle (12 o'clock) position.
  2. Turn the ignition switch to the ON position (do not start the engine).
  3. Within 10 seconds of turning the ignition switch from the OFF to the ON position, perform the following rotations (sweeps) of the temperature control.
    • From the 12 o'clock position, rotate the temperature control counter-clockwise to the full cold position. Pause one second.
    • Rotate the control clockwise to the full hot position. Pause one second.
    • Rotate the control counter-clockwise to the full cold position. Pause one second.
    • Rotate the control clockwise to the full hot position. Pause one second.
    • Rotate the control counter-clockwise to the full cold position.

Where is the blower motor relay located on a 2010 jeep liberty


on all speeds, is it dead sounding or only no air flow???
wow no symptoms posted only this goose chase deal.

use the scan tool yet? see all DTC errors.
2008 cars can report most cause of lost power etc,
not scanning, invites expensive gue$$ing.!!

HVAC 101: (
gdoes the motor have 12vdc on high? at connector to it>?
on all speed's (now that is a KEY FACT there)

  1. defeat air bag first or die , fiddling these parts.
  2. do the HVAC calibration yet? per FSM.
  3. scan it yet ,if not you will guess wrong. I promise,
  4. i have to stop my online page ,is missing the wiring sections.

Check engine light on..code short runner valve control malfuction


P1004 - SHORT RUNNER VALVE CONTROL PERFORMANCE

Sound like something came loose. If you cannot find it you need to take it to the dealer so they can perform these diagnostics. Should be under warranty.

The engine performance and power output is enhanced through the use of the "short runner valve" (SRV) system. The SRV system allows the intake charge air to bypass the long intake manifold runners between the intake manifold plenum and the intake manifold interface to the cylinder heads by providing a shorter runner directly between the plenum and the cylinder head interface.

The SRV position is controlled by a pneumatic/spring actuator and electronic solenoid valve. When the solenoid is not energized (the "rest" position), the SRV is held in the closed position. When the solenoid is energized the SRV is moved and held in its opened position. There is a set of enable conditions including a minimum engine coolant and ambient temperature, SRV enable, and Powertrain Coordinator load enable condition. If any of these conditions are not met, then the SRV valve is de-energized (closed).

* When Monitored: With the engine run time above a calibrated value, battery voltage greater than 10.4 volts, ECT within a specific range, and the Short Runner Valve Assembly (SRV) control active.
* Set Condition: The Powertrain Control Module (PCM) compares the circuit feedback to a calibrated closed range, between 75% & 85% Pulse Width Modulated (PWM) duty cycle, when the circuit is de-energized or to a calibrated open range, between 35% & 55% PWM duty cycle, when the circuit is energized. If the value is determined to be out of the calibrated range in either the de-energized, greater than 85% duty cycle or less than 75% duty cycle, or energized, greater than 55% duty cycle or less than 35% duty cycle, state for more than a calibrated amount of time, this DTC will set.

Possible Causes
(F344) ASD RELAY OUTPUT CIRCUIT OPEN OR HIGH RESISTANCE
(K237) SHORT RUNNER VALVE (SRV) SIGNAL CIRCUIT SHORTED TO GROUND
(K237) SHORT RUNNER VALVE (SRV) SIGNAL CIRCUIT OPEN OR HIGH RESISTANCE
(K238) SHORT RUNNER VALVE (SRV) CONTROL CIRCUIT SHORTED TO GROUND
(K238) SHORT RUNNER VALVE (SRV) CONTROL CIRCUIT OPEN OR HIGH RESISTANCE SHORT RUNNER VALVE (SRV) ASSEMBLY

2001 Lincoln LS. Selecting seat/mirror/steering wheel positions works for all except the driver seat. Could this be a fuse/breaker problem? If so, where are they? Is there other possible cause for this?


you may need to have the dealer calibrate the seat with his diagnostic tool. I would guess ariund 1 hr labor time.

info:

Principles of Operation
Driver Power Seat The driver power seat is controlled by the driver seat module (DSM). The DSM does not need to be configured, however the drive seat does need to be calibrated when the DSM is installed. The driver seat regulator control switch provides voltage to the DSM when activated. The neutral position of each driver seat regulator control switch position is a ground state through the seat regulator control switch contacts. A voltage input causes the DSM to power the appropriate motor until the input is removed. Ground is the normal state of the motor circuits through the DSM and is not switched to control the motors. The DSM internally switches the appropriate line from ground to power to adjust the motors.
As the seat is adjusted, the DSM constantly monitors the motor position sensors to record the current seat position. The DSM will remove power from the motor upon termination of the seat regulator control switch input or if the DSM does not see movement from the motor by monitoring the position sensor. The DSM must be calibrated to the seat track it is controlling. For additional information, refer to Seat Calibration. Once the DSM is calibrated to the seat track, it will only allow movement within the calibrated range.
Seat Calibration The DSM is calibrated using a scan tool. The calibration procedure automatically powers the driver power seat through its full range of motion and records the full stop positions by monitoring the motor position sensors. Once the full stop positions or range of the seat have been recorded, the DSM will only operate within the calibrated range. Any input attempting to drive the seat beyond the calibrated range will be ignored. This calibration is used for all seat control functions including manual switch control and memory recall positioning. During the seat calibration, the DSM may identify a function that is inoperative, such as a position sensor not changing. If the DSM identifies a concern that has a related diagnostic trouble code (DTC), the DSM will set the related DTC at the end of the validation procedure.
The calibration procedure powers the seat track adjustments to the end of their travel, which is determined by the DSM seeing a change of state in the motor position sensors. If there is a concern with the seat track or motor position sensor that limits the travel, the DSM will interpret the stopping point as the end of travel and store the position. The DSM is not able to determine if the seat has moved to its full travel position. It is only capable of monitoring and storing the amount of travel seen by the position sensor changing states.
For additional information on carrying out the power seat calibration procedure, refer to the scan tool operating manual.
Memory Seat Memory seat positioning can be recalled with the memory switches on the driver door panel or a programmed remote keyless entry transmitter. In either case, the DSM receives a memory recall 1 or 2 command from the driver door module (DDM) over the SCP communication network. The memory recall switches are a hardwired input to the DDM. The DDM also receives the remote keyless entry transmitter signals. Once a valid memory recall command is received from the DDM, the DSM moves the drivers seat to the position stored in memory by powering the appropriate motors and monitoring the motor position sensors until the position is reached.
Easy Exit/Easy Entry The easy exit function moves the seat backwards about two inches when the ignition key is removed from the ignition switch. The DSM receives a key out command over the SCP communication network and powers the driver seat rearward. This function will not operate if the seat is less than the travel distance to the end of the track, or the function has been deactivated at the message center driver personality settings. The DSM will also cancel this operation if a valid input command is received, such as the seat regulator control switch or memory recall request.
The DSM will record the current seat position before powering the seat for a easy exit function. This recorded position will be used to return the seat to this position on the easy entry operation. During easy entry operation, the seat is returned to the position previous to the easy exit operation. Easy entry operation will be cancelled if a valid input command is received by the DSM.
Passenger Power Seat The passenger power seat motors are hardwired to the passenger seat regulator control switch. The circuits are normally at ground through the seat regulator control switch. The individual circuit is switched to power when the specific adjustment position is selected.
Heated Seats The driver and passenger heated seats share a common battery and ignition feed. A separate shared ignition source supplies the heated seat switches. When the heated seat switch is pressed with the ignition switch in RUN, a momentary voltage signal is sent to the heated seat module. The heated seat module then supplies power to the heating element circuit. The cushion element and seat backrest element are wired in series and powered by the same output. The heated seat module also will ground the separate indicator circuit at the heated seat switch to indicate an ON state. The heated seat module will remain on until the heated seat switch is pressed and a momentary voltage signal is received, or until 10 minutes expire. If the ignition source is removed from the module, the heated seat module will enter an off state and will not return to ON until the switch is once again pressed with the ignition switch in RUN. The heated seat module is designed to heat the seat to 37.5°C (99.5°F) and maintain the temperature until time-out or switched off. This temperature is maintained by the heated seat module monitoring the temperature sensor located in the seat cushion element, and adjusting the current flow to the heating elements.
Inspection and Verification
  1. Verify the customer concern by operating the system.
  1. Visually inspect for obvious signs of mechanical or electrical damage.
