Ltpws

[jgmotto]

I have a LTPWS light on. Is there any way to determine which wheel sensor is faulty other than dismounting tires one at a time? Any other tests that can be done to troubleshoot this system?

Read out the DTCs by connecting DLC terminal 6 to 5 to flash LTPWS. Look for 23, 33, 43, 53 or 24, 34, 44, 54. All codes will be preceded with DTC 12. DTC 99 is possible receiver fault.

Thanks for the reply. I guess I should have mentioned that this is on a 1989 model. I'm not familiar with those terminal numbers. Are there similar ones on the '89?

Well I guess you know what happens when I assume. I should have asked what car you had to begin with. With an '89 I'm not sure. I will have to do some reading on that and defer right now.

look here for a good tutorial for '89 LTPWS diagnostics.

Thanks for the feedback. The article has some great methods to troubleshoot the system. I will give it a shot.
