09 Cayenne S ABS Warning Light and Error Code 1324

[Davet18]

After a 3 hour highway drive, stopped at a traffic light, vehicle jerked while stopping and ABS warning light came on.  Pulled into a gas station and filled up.  After filling the sequence is as follows:

Started the vehicle

• ABS light came on immediately
• Speedometer floated up to 85 mph then slowly returned to 0
• Put the vehicle in reverse then drive and it would not move

• Shut off vehicle and waited a minute

Started the vehicle

• No ABS light
• Speedometer registered 0
• Put vehicle in reverse backed out and drove away normally.

Two days later drove 3 hours back home hoping it would make it. No problems and no ABS warning light.  Analyzed with Durametric, Only Error Code 1324 Transfer Box Control Unit

 

Recent repair: I had Error Code 2042 and no 4 wheel drive in November so I replaced the Transfer Case Controller and servo motor.  Code Cleared and 4 wheel drive works fine.

Only other issue is I occasionally have sluggish or hard steering.  I’m thinking that I may have a failing wheel speed sensor because ABS is dependent on wheel speed sensor input, speedometer is driven off the ABS module, and variable steering is also based on vehicle speed, which I think is driven off either the vehicle speedometer or ABS.  Seems that the issues are all tied back to vehicle speed and wheel speed sensors.

Does anyone know if an intermittent wheel speed sensor fault would be stored in ABS memory and detectable by Durametrics?  Any suggestions for analyzing the problem would be appreciated.
