4. Is resistance within specifications? 

YES  



Substitute with a known-good PCM/TCM and check for proper operation. If the problem is 
corrected, replace PCM/TCM as necessary and then go to "VERIFICATION OF VEHICLE 
REPAIR" procedure.  

NO  



Replace "TRANSAXLE RANGE SWITCH" as necessary and Go to "VERIFICATION OF 
VEHICLE REPAIR" procedure.  

VERIFICATION OF VEHICLE REPAIR 

After a repair, it is essential to verify that the fault has been corrected. 

1. Connect scan tool and select "Diagnostic Trouble Codes (DTCs)" mode.
