Parking w/ brake Control Module location?

[c34webb]

I purchased this module to repair my wrecked 24 integra. Can't seem to find out where in the world it goes. Any ideas? part number 39670-3S5-A05

Not sure whether this will be of any help, but on the RDX it's in the rear left C- (or D-?) pillar, according to the link below. May be a good place to start looking on the Integra.

The diagram on Dreamshop also shows the Integra one toward the left rear side, although it's not as specific as to where it's located. Good luck!

Interior Trim Area File it will be listed as "AC" in the diagram

EDIT: realize the file doesn't look as easy to read as the online format lol, but if you scroll down you'll see it under the AC sub procedure. Ill attach a picture for your convenience

Thanks so much! Found it, replaced it and still an issue. Dang.

What code are you getting from the module? Or is it a no communication issue

B2600-54. Not sure what that equates to.

 

[jayy_swish]

B2600-54 is parking sensor not initialized, try doing the rest on the parking module:

EDIT: just saw your other thread. Can you try erasing the code and seeing if it’s selectable? If not I would go into the data list in the module and see if all sensors are providing data

Yeah I’m not able to reset the PSR system via the dash since the function is in red. The data shows every sensor at 0 yrds even on a moving graph while moving objects closer to the sensors.

 

[jayy_swish]

If there's no data being transmitted when you move something closer or further away then I would verify power and grounds at the module and then at the individual sensors.

As an added check I would verify the connection from the sensors to the module by Ohms checking the wires, just to rule out an open circuit, and check for a short also.

Excellent stuff. Running the multimeter on the control unit connector I'm using the power source (10) to the ground control units ground (15) 12.3v, Ground for from sensors (5) 10v, and Ground from rear sensors (16) .002v. Not sure why I'm getting such a variance but I assume somethings going on with the rear sensor which is weird because there was never any damage in the rear only the front.

Hoping you might have some ideas.
I owe you big time.!

For the rears try placing the cars in reverse and see if you get the 12v while using the ground (16). next step might be tedious, but you gotta check out each individual sensor and see if they’re getting the 12 V to be sure

edit: I dont see any indication whether the sensors are ground switched or power switched. But my guess is like most modules it’s ground switched

I ran ohm resistance on all of the parking sensors and on one side of a sensor isn't reading anything as all of the others run similar resistance on both sides of the sensor. I'm assuming that could be the issue. Does that sound right?

When testing the rear make sure all connectors and module is disconnected at all components, same when testing the front sensors.

Right Rear Corner Sensor Connector:
3: is your communication line (have 1 test lead connected here and the other at right rear center sensor connector #2, Ohms should be under 2, ideally around or less 0.8Ohms)
4: Test Power (+)
1: Test Ground (-)

Right Rear Center Sensor Connector:
2: is your communication line with RR Corner Sensor
4: Test Power (+)
1: Test Ground (-)
3: is your communication line (have 1 test lead connected here and the other at Left Rear Center sensor connector #2, Ohms should be under 2, ideally around or less 0.8Ohms)

Left Rear Center Sensor Connector:
2: is your communication line with RR Center Sensor
4: Test Power (+)
1: Test Ground (-)
3: is your communication line (have 1 test lead connected here and the other at Left Rear Corner sensor connector #2, Ohms should be under 2, ideally around or less 0.8Ohms)

Left Rear Corner Sensor Connector:
2: is your communication line with LR Center Sensor
4: Test Power (+)
1: Test Ground (-)
3: is your communication line (have 1 test lead connected here and the other at Parking Module #17 , Ohms should be under 2, ideally around or less 0.8Ohms)

This rules out any open in the communication wires and you test make sure power and grounds are getting to the sensors. Do the same with the front. I never liked testing resistance on the components itself. But if sensors are receiving power and grounds as well as the the line's not being open in the communication lines then I would rule it being that sensor you tested. You are able to talk to the parking and back up module with the scanner right? To rule out F-Can line issues.

Pulling 12.36v on all connectors and .7ohms or lower from each connector communications line to the #2 reciprocal on all front and rear sensors. From 17 on the parking module plug to the rear left I'm getting .5 ohms.

I have the car completely taken apart so I'm open to trying anything else. I've also replaced the rear left sensor and still the same issues.

I’m away from my work computer so won’t be able to do much, but for shits and giggles.. to rule out any stupid setting preventing you from initializing your sensors. Do a vehicle setting’s reset from the radio
