瀚慐ither 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:
瀚慖f DTC B0081 39 sets in the SDM then replace the PPS module.
* SDM DTC B0081 71:
