Hello All,
I have an '05 4R Limited V6 4WD approximately 126K miles
VSC Ebrake Trac Abs lights all on (No CEL)
Speedo is working
going into gear fine
Brakes work as they should, not locking up(pedal is a little spongy but felt like that for years to me) I have have replaced front (twice) and 1 rear calipers over the 11 years of owning it.
Here are my codes: All under Toyota ABS scan
U0126 - Lost Comms w/ steering angle sensor module
U0124 - Lost Comms w/ lateral acceleration sensor module
U0123 - Lost Comms w/ Yaw Rate sensor module
U0100 - Lost Comms w/ ECM/PCM "A"
U0073 - Control Module Communication Bus "A" Off
C1238 - Metal stick to speed sensor (RR)
C1223 - Malfunction in ABS control system
C0215 - Left rear wheel speed sensor signal malfunction
C0210 - Right rear wheel speed sensor signal malfunction
C0205 - Left front wheel speed sensor signal malfunction
C0200 - Right front wheel speed sensor signal malfunction
At first the lights were on and off intermittently over the course of a week, now they stay on, for months now.
Had to personal mechanic and said they could not communicate with the ABS module via a scan tool and are assuming that it needs replacement.
They did not really dig into the issue since they were doing other work as well and wanted to see how I want to proceed.
I realize the dealer wants an absurd amount for the module/master cylinder assembly so I am willing to look at used ones.
I am trying to verify the 2005 model year correct part number.
Is this module 03-05 model years or 05-09 model years?
I see contradictory parts #'s when I search.
And from what I see will I need to bring it somewhere to be bleed through a scan tool properly after changing the unit because of the solenoids needing to be pulsed during the process.
Short of any obvious wiring issues, does this sound like something that is an "easy" fix (brake switch, zero point calibration, fuse/relay)
Anyone know of fuse or relay locations that might be the culprit?
Any known spots to check for rotted wiring to module?
Thanks in advance, I tried to provide as much info as possible so I'm not answering obvious questions all week without seeing any remedies. I unfortunately only have the weekends to tinker.
