Body Ecu

Hello everyone. I'm wondering if someone can give me a good suggestion.

My car is 2005 4runner and for more than a year , my power windows only work on the driver side.
The windows lock button on the driver side is off

Problem:

Only driver-side window works
Rear wiper INOP
Defogger INOP
rear glass INOP

I brought the car to the dealership to fix my steering because it was binding and since I'm already there I ask them to give me an estimate to fix my windows. So after paying $712 ( 595 for the steering shaft and 117 for the window diagnosis) the tech said the problem is the body Ecu located on the dashboard. It will cost me additional 1250 to get it installed.

I guess my question is , is $1250 a total ripoff? Does anybody here dealt with this problem?

Thanks

Depending on your options package, the Body Control Module is between ~$300 and ~$600 dollars plus labor, plus programming. $1250 isn't a total rip-off but you're definitely paying a premium to have a dealer do it. The $117 diagnosis fee should credited towards the job. A trusted indy can probably knock a couple hundred bucks off that price... a really good indy will call the salvage yards and pick up a used BCM but there would be no warranty on parts.

In this case I think the warranty is worth it. Whomever does the work needs to make sure they know why the BCM failed. It's rare that they just quit (but it does happen). Usually something causes it to fail, like a short in the harness or damage. If there is a short somewhere and they don't find it, it will just fry the next BCM.

On a side note; dealers charge highway robbery prices for "programming" because anytime they flash a module there is a small (but disproportionately high) chance they can nuke the ECU (or BCM or TCU, etc.). If they bone it, it's on them and they have no recourse from Toyota corporate or the supplier. Independent shops normally cover that risk in their parts markup and include programming as a part of labor instead of a separate line item.
 
Thank so much for taking the time to respond. It sucks that it cost so much to fix a 13 yr old car regarding this issue. But still , I'm a lifelong 4runner fan and still happy with it.
 
Body ECU on 2003 4Runner 4.7

Hi, Can you anyone tell me if the Body ECU can affect starter circuit? Reason is my car is cranking on the "on" position and won't stop until I pull the neg cable. I also tried replacing the ECM but that's not the problem. Replaced the ignition switch also. Also the car doesn't fire and seems like no gas pressure too. All this happened after the car over-heated. Any suggestions?

Guess everyone is stumped. Anyone know if the immobilizer is the same as the body control module?

Immobilizer module is above the glove compartment near the alarm module. That is what remembers the chip code. It shouldn't start at all if this was the problem. Sounds like starter relay is/was stuck or starter is/was sticking on. Also assume you fixed it by now...? Also, in related matters, the key-less entry module is located in the drivers rear pillar.

Hi,

I replaced my Body ECU a couple weeks ago. I thought it was the fault of my electrical problem, but I was wrong. I purchased it for about $80 including tax and shipping from Whitey's auto wrecking in Spokane, WA. It doesn't need to be programmed. However, some options may be different. For example, my old ECU will unlock the back doors when car placed in park or whatever... the new-used one does not. So, in that sense it could use some programming but not required. Also, I used a 04 version in my 03 so it doesn't have to be the same year... but may need to stay within 03-05 and 06-09 ranges. I will be placing my old one for sale on Ebay soon once I am sure that the sun visor is my problem, lol.
 
Some things from the 2004 manual

Disconnecting the batterry will cause a loss of almost all functions that are programable to revert back to its previous state.

You can set the following automatic
door locking and unlocking functions.
(a) Locking linked with the shift position
All the side doors and back door are
locked automatically when the automatic
transmission selector lever is moved out
of the “P” position with the engine running
(including ignition switch in the “ON” position)
and all the side doors and back door
are closed. This function is the default
setting for new vehicles.
(b) Unlocking linked with the shift position
All the side doors and back door are unlocked
automatically when the automatic
transmission selector lever is moved to
the “P” position with the ignition switch in
the “ON” position.
(c) Locking linked with the vehicle
speed
All the side doors and back door are
locked automatically when the vehicle
speed reaches 20 km/h (12 mph) or higher.
However, if any of the side doors and
back door is unlocked during driving, this
auto locking function will not operate until
the unlocked door is opened once.

1. All the side doors and back door lock and
unlock simultaneously with the driver’s
door. In the driver’s door lock, turning the
key once will unlock the driver’s door and
twice in succession will unlock all the side
doors and back door simultaneously.

2.To lock: Push the switch down on the
front side.
To unlock: Push the switch down on the
rear side.
Operating the switch simultaneously locks
or unlocks all the side doors and back
door.
If you do either of the following, no side
door or back door can be unlocked with
the power door lock switch.
Lock all the side doors and back door
with the key or wireless remote control
transmitter when all the side doors and
back door are closed.
Open the driver’s door or front passenger’s
door and move the inside lock
knobs of both front doors to the lock
position, then close the front doors.
The power door lock switch can be reset
in the following ways.
Turn the ignition key to “ON”.
Unlock all the side doors and back
door with the key or wireless remote
control transmitter.
Unlock the driver’s door or front passenger’s
door with the inside lock
knob, and then unlock all the doors
and back door with the power door
lock switch.
This unlocking protection with the power
door lock switch can be disabled. For details,
contact your Toyota dealer.

3. (d) Unlocking linked with opening the
driver’s door
All the side doors and back door are unlocked
automatically when the driver’s
door is opened within 10 seconds after
the ignition switch is turned from “ON” to
the “ACC” or “LOCK” position.
SETTING THE FUNCTIONS
1. Close all the side doors and back door.
2. Turn the ignition switch to the “ON”
position.
3. Within 10 seconds after the ignition
switch is turned to the “ON” position;
To set function (a)
Push and hold the front of the power
door lock switch for 5 seconds with the
automatic transmission selector lever in
the “P” position.
To set function (b)
Push and hold the rear of the power
door lock switch for 5 seconds with the
automatic transmission selector lever in
the “P” position.
To set function (c)
Push and hold the front of the power
door lock switch for 5 seconds with the
automatic transmission selector lever in
any position except “P”.
To set function (d)
Push and hold the rear of the power
door lock switch for 5 seconds with the
automatic transmission selector lever in
any position except “P”.
All the side doors and back door are automatically
lock and unlock when you release
the power door lock switch. This
indicates that the function is set. If all the
side doors and back door do not lock and
unlock, the time the switch was held may
have been too short or too long. Perform
the procedure over again starting from
step 1.
If you want to cancel a function, repeat
the procedure. Each time you perform the
procedure, the function is set or cancelled.

4. If your rear window, defogger and wipers do not work it is usually because the back window is not closed ALL the way, and that means an 1/8th of an inch can cause this to happen, just re hit "up" to make sure.

5. The sunroof opening all the way with the push of the button once.

To normalize the moon roof, push and
hold the switch on the “TILT UP” side until
the moon roof tilts all the way up and
then tilts down a little automatically.
