Tech Tips (Routan Turn Signals Will Not Activate after TIPM Replacement): The replacement Totally Integrated Power Module (TIPM) contains revised software that changes the TIPM operation and alters the front exterior lighting of the vehicle. The vehicle wiring may need to be modified to maintain turn signal operation. This document informs how to modify the vehicle wiring.
What a TSB means. Technical service bulletins are repair guidance manufacturers send to dealers — they are not recalls, and repairs are not automatically free (warranty extensions are an exception worth checking). The full document is available via NHTSA’s vehicle lookup.
