U0167 Lost Communication With Vehicle Immobilizer Control Module

Check engine lightUsually off
EmissionsNot relevant
Drive cycleNot required
Limp modeNo

U0167 means the vehicle immobilizer control module, which checks the transponder in the key and then releases the engine controller, can no longer be heard on the bus. Since the key handshake cannot complete, the engine typically cranks without firing or does not crank at all. Ford's 2014 Boss 302S code list and the Saab 9-5 code list contain U0167. Triumph reported it in 2024 on Speed 400 and Scrambler 400 X motorcycles after an immobiliser software update: the bike would not start, and switching off fully and repeating the calibration download was the remedy. Chrysler deviates from the J2012 name: a 2011 Jeep field report filed with NHTSA assigns U0167 to an intrusion transceiver module. U0168 is the separate security module.
