An issue was discovered with StarSCAN version 8.02 when performing the “Vehicle Configuration Update” procedure on 2008 Jeep Commander models. This version of the StarSCAN erroneously set a MIL illumination for DTC P0481 (cooling fan 2 control circuit). Version 8.03 of StarSCAN corrected this condition.

If the vehicle comes in with DTC P0481, ensure that StarSCAN is operating with version 8.03 and performs a “Vehicle Configuration Update” procedure.

Connect the StarSCAN to the vehicle and with the ignition in the run position, activate the high speed radiator fan relay.

Read the DTCs, and if the DTC returns, further diagnosis is required.
