锟斤拷 Either an incorrect replacement PPS module or SDM was placed in this vehicle. Check and make sure the part #'s are correct for each



module. If both part #'s are correct clear this DTC and see if DTC B0081 3A resets as a current DTC. If DTC B0081 3A resets then



replace the PPS module. Clear DTCs again and check if DTC B0081 3A sets as current again. If DTC B0081 3A sets again then



replace the SDM.



* SDM DTC B0081 39:



锟斤拷 If DTC B0081 39 sets in the SDM then replace the PPS module.



* SDM DTC B0081 71:



锟斤拷 If DTC B0081 71 sets in the SDM check and see if the SDM also sets DTC U0170. If DTC U0170 is set in the SDM then diagnose



DTC U0170. Refer to Diagnostic Trouble Code (DTC) List - Vehicle (See: Diagnostic Trouble Code Descriptions/Diagnostic



Trouble Code (DTC) List - Vehicle). If DTC U0170 is not set in the SDM then check the connections at the SDM and PPS module.



Clear DTC's and check if DTC B0081 71 sets as current. If DTC B0081 71 sets as current again then replace the PPS module.
