1. Clear the DTC using the HDS (see HOW TO CLEAR DTCS ).  

2. Turn the ignition switch ON (II).  

3. Verify the DTC. 

Does the ABS indicator come on, and are DTCs 31, 32, 33, 34, 35, 36, 37, and/or 38 indicated?

YES: Check for loose terminals in the VSA control unit 47P connector. If necessary,

DTC 41, 42, 43, 44: WHEEL LOCK 

1. Test-drive the vehicle, and check for brake drag by duplicating city driving at speeds over 30 mph (50 

km/h). Use the brakes often. 

Do the brakes drag? 

YES: Repair the brake drag.  

NO: Go to step 2.  

2. Check the installation of the appropriate wheel sensor (see Fig. 55 ) (see WHEEL SENSOR 

INSPECTION ). 

Is it correct? 

YES: If the DTC does not reappear, the most probable cause for the DTC is that the vehicle 
might have lost traction in poor weather and spun around.  

NO: Reinstall or replace the wheel sensor (see WHEEL SENSOR REPLACEMENT ).
