Has anyone ever gotten this error before? When vehicle is coming to a stop and brake pedal is close to fully depressed, the ABS activates and pulses for a moment then the ABS light comes on and stays on even though I am on dry pavement. Upon retrieving the code, I get an ABS error code of 26-1 All Wheel Sensor No Pulse and a VTM-4 code of 24-1 RR Wheel Sensor Failure. Do you think it could be something more than just a sensor replacement? Just curious before I spend $75 on a new part. Also do you think a bad ABS sensor could be causing my VTM-4 code 78-1 VTM-4 CTRL Unit Failure? Or my 77-1 Powertrain System Failure? I already have the gallon of VTM-4 fluid and will go tomorrow to pick up the differential temp sensor for $20 and replace it to give that a shot first. I'm really hoping it's not a bad control unit. Colorado native here and would really like to have 4WD for winter. TIA

When the shop did the alignment on my Pilot last time they damaged the sensor. I found it out by taking a multimeter and measuring across the orange plug on the sensor side. It read open while the normal is 1.4 kOhm.
I also got the matching code and replaced the sensor with Rock Auto's NTK. The light went away but I did not scan for nor cleared the codes. Been fine ever since.
I cleared the codes much later when I bought the scan tool and I immediately got the VSA light and code and had to do VSA sensor neutral position reset procedure. Look for my thread on that here for details.

Keep in mind that the ABS sensor goes through the ABS Control Unit before it hits the VTM-4 control module. You might want to check the connection between the two first.
I'm a little skeptical about all the wheel sensors failing at the same time or one sensor causing an "All wheel sensor no pulse" error, but anything is possible.

I was able to buy a salvage VTM-4 control module and ABS Control Module on line for about $60 each. Unfortunately I'm still chasing an intermittent VTM-4 wheel sensor error.

Where is the ABS module located on the car?

I did double check to make sure the connectors are plugged in and snug. I'm leaning towards the people who did the alignment and broke it since I didn't have the issue until after that.

If it's like an alignment place I first went to before finding a reputable one, brace yourself for those guys' capacity for CYA denials after a job they know full well they botched.
