Question about 2009 Nissan Altima 2.5

1 Answer

2009 Altima, 2.5. We recently had the BCM and radio replaced, transmission control module reprogrammed, engine torque rods and buffer assembly replaced by Nissan under an extended warranty. After getting the car back from Nissan the heater/AC only blows from the dash vents. Took it back to Nissan, they looked at it and said "found piece of HVAC case broken off which attaches to the mode door lever, recommend replace case". My question is: is the BCM and/or TCM anywhere near the mode door lever or do you see accidently breaking the piece by doing any of the above service?

Sorry to tell you this, but neither of those computers would require any work on the HVAC case. The BCM is located above the instrument cluster. The TCM is located under the hood [which is a very poor location] I'm a 35 year professional mechanic. Sorry to tell you this, but my opinion of the Altima is very poor. These things have all sorts of problems, are hard to work on and the parts are very expensive. Lots of recalls and TSBs [technical service bulletins] TSB is dealer speak for "oops, we goofed". You can't blame the dealer for this one.

Do bcm need to be reprogramed


Has to be programmed ,yes .
Body Control Module (BCM) Replacement
If the BCM is replaced, the following procedures must be performed in the subsequent order:
• BCM Reprogramming--Refer to Body Control Module (BCM) Programming/RPO Configuration in Computer/Integrating Systems for replacement, setup, and programming.
• Theft Learn--Refer to Programming Theft Deterrent System Components in Theft Deterrent.

A new body control module (BCM) must be programmed with the proper regular production option (RPO) configurations. The BCM stores the information regarding the vehicle options and if the BCM is not properly configured with the correct RPO codes, the BCM will not control all of the features properly. The Tech 2 software will automatically prompt you with the RPO available for the vehicle. Ensure that the following conditions exist in order to prepare for BCM programming:
• The battery is fully charged.
• The ignition switch is in the ON position.
• The data link connector (DLC) is accessible.
• All disconnected modules and devices are reconnected before programming.
To setup a new BCM, access the Vehicle Control Systems in Computer/Integrating Systems menu on the scan tool to program the BCM. Select Module Replacement/Setup and follow the instructions on the scan tool.
If the BCM fails to accept the program, perform the following steps:
• Inspect all BCM connections.
• Verify that the scan tool has the latest software version.

My 2009 Pontiac G5 started doing this about 3 months ago. On startup, the door locks make noise and it takes a while to shift out of park


Have the vehicle checked for DTC'S diagnostic trouble codes stored in the BCM - body control module . Everything is electroniclly controlled .
Automatic Transmission Shift Lock Control Description and Operation
The automatic transmission shift lock control system is a safety device that prevents an inadvertent shift out of PARK when the engine is running. The driver must press the brake pedal before moving the shift lever out of the PARK position. The system consists of the following components:
• The automatic transmission shift lock solenoid (serviced as the automatic transmission shift lock actuator), as well as the body control module (BCM) and the engine control module (ECM). The shift lock solenoid is located within the floor shift control assembly with vehicles equipped with floor shift.
• The BCM controls the voltage to the shift lock control solenoid through the shift lock control solenoid controlled voltage circuit. The following conditions must be met before the BCM will remove voltage from the shift lock solenoid:
- The ignition is in the ON position.
- The engine control module (ECM) sends an input via GMLAN serial data to the BCM indicating the transmission is in the PARK position.
- The BCM determines the brake pedal is applied according the brake pedal position.
Since the shift lock control solenoid is permanently grounded, the BCM supplies voltage to the automatic transmission shift lock control solenoid, mechanically locking the shift lever in the PARK position as the solenoid energizes. When the brake pedal is applied, the BCM turns the control voltage output of the shift lock control solenoid OFF, de-energizing the shift lock control solenoid. The de-energized solenoid releases the mechanical lock allowing the driver to move the shift lever out of the PARK position. When the transmission is out of the PARK position, the shift lock control solenoid remains de-energized.
During remote start operation, the BCM will energize the shift lock control circuit, locking the shift lever in the PARK position.

The BCM supplies and monitors a reference voltage to the door lock switch through the door lock switch lock/unlock signal circuit. The door lock switch also receives a constant ground source. If a door lock switch is placed in the lock position, the reference voltage is taken directly to ground and the BCM senses 0.0 volts on the signal circuit. If a door lock switch is placed in the unlock position, the reference voltage is taken to ground through a 15k ohm resister that is internal to the door lock switches and senses approximately 2.9 volts on the signal circuit. This is how the BCM determines what portion of the door lock switch was activated.

I hsve a 2008 saturn sky base 2.4L. The dealer says I need a new body control module. My question does the new BCM require reprogramming? If it doesn't then I will replace myself. Thanks


Body Control Module (BCM) Replacement and Reprogramming
If the BCM is replaced or requires reprogramming, the following procedures must be performed in the specified order:
BCM Setup -- Using a scan tool, go to Vehicle Control Systems » Computer/Integrating Systems » Module Setup » Body Control Module. Select Setup BCM and follow the on-screen instructions, making sure to select the proper RPOs and input the VIN correctly.
BPP Sensor Calibration--Refer to Brake Pedal Position Sensor Calibration
Program Key Fobs--Refer to Transmitter Programming
Setup SDM Part Number in BCM -- Using a scan tool, go to Vehicle Control Systems » Computer/Integrating Systems » Module Setup » Body Control Module. Select Setup SDM Part Number in BCM and follow the on-screen instructions.

How do i replace the transmission fluid of 2009 nissan altima


two ways to do it
1-- drop the pan and drain half the oil and check / clean the filter
2---take it to an accredited auto transmission shop and have it changed with the engine running--- changes all the oil including what is in the torque converter with no need to drop the pan
method 2 is more expansive as you have to use more oil but the result is better as it removes any contaminants from the torque converter that method 1 does not do

Two codes coming up on car even after fixing alot on car now need to figure out low cost ways to fix P0744 & P0722 code issues spent 1,800 on car & have spent 1,400 already in parts & labor.


you need a better mechanic that traces ALL of the possibilities of each code, not just read the code and trow in a part hoping that it's fixed ~ it can be wiring as well, not just plug in a new part as mentioned on the 2nd trouble code to the vehicle speed sensor

P0744 Torque Converter Clutch Circuit Intermittent


P0722 Output Speed Sensor No Signal

the first of the 2 looks to be more intensive to trace and find out the problem & the 0722 is the easier job for an intermediate mechanic to trace the wiring for continuity

Does the BCM control anything with the keyless system? Mine will not work once the delay lighting is off, can set it but not unlock it when you come back. Once you unlock with the key and open the d


NO, BCM stands for body control module, you car also has a PCM who controls the engine management and also transmission.
You might need to replace the BCM module and get it reprogrammed as it is the one who holds in the memory the car mileage and other info.

obviously refers to auto trans , could just need the trans fluid level topping up or even changing , if this does'nt resolve the problem then a more in depth diagnosis would be required at a repair shop as could be the ECU for example but do the fluid checks and go from ther ,keep me posted
