P1C86 in short

On Jeep and Dodge models with an electronic shifter, P1C86 means the gear-position (PRNDL) display circuit drew current outside its expected range. Owners see a 'Service shifter' message, sometimes with every gear lamp lit. FCA points to harness connections, the display bezel or the shifter; ask a dealer to check it.

Jeep and Dodge models with an electronic shifter run a small circuit that lights the P-R-N-D display on the shifter. The shifter module watches the current in that circuit.

P1C86 sets when that current is out of range. FCA's Jeep Cherokee bulletin tells dealers to inspect the harness connections first and, if the code is still active, to replace only the display bezel rather than the whole shifter. A separate bulletin says that servicing the shifter without disconnecting the battery can store the code.

Owners of 2016-2018 Cherokees report the 'Service shifter' message and repeated visits, with the fault returning after the harness, bezel or shifter was replaced. Keep the repair order showing what was replaced.

Pick your make

P1C86 is a manufacturer-specific code: its meaning depends on who built the car.

Other makes: meaning not verified. Check with a scan tool that reads manufacturer definitions.

Most likely causes

  1. Harness or connector at the shifter

    Supported by vehicle data
    Why it ranks here
    FCA's Cherokee bulletin has dealers inspect the harness connections before replacing parts, and one owner says a harness replacement did not hold.
    What would change this
    Likelier if the message comes and goes or follows a bump or console work.

  2. Display bezel (PRNDM) or shifter assembly

    Supported by vehicle data
    Why it ranks here
    The bulletin names the bezel as the part to replace if the code stays active after the harness check; owners report the shifter replaced and the fault returning.
    What would change this
    Likelier if the code is active with the harness connections good.

  3. Code stored during shifter or console service

    Supported by vehicle data
    Why it ranks here
    A Dodge Durango and Jeep Grand Cherokee bulletin says servicing the shifter without disconnecting the battery can store P1C86-14, and the code should be cleared before replacing the shifter.
    What would change this
    Likelier if the code appeared right after shifter or console work and clears with no other fault.

What to test first

Start at step 1. Each result tells you what it means and where to go next.

  1. Read the code with its suffix (-1D, -14, -92) and note whether it is active or stored, and any U1465 or other network codes

    Low riskTool: OBD-II scan tool that reads the shifter module

    • IfAppeared right after shifter or console work

      It meansClear it and see if it returns; the Durango/Grand Cherokee bulletin says to clear before replacing the shifter.

      Go to step 2

    • IfActive, with the 'Service shifter' message

      It meansAsk a dealer to inspect the harness connections before replacing parts.

      Points to: Harness or connector at the shifter

  2. After shifter or console work, disconnect the negative battery cable, wait two minutes, reconnect, then clear the code and recheck

    Use cautionTool: Wrench, scan tool

    Warning:Park with the parking brake set and the key out; disconnecting the battery resets other settings such as the radio and windows and can set unrelated codes.

Symptoms

  • 'Service shifter' message in the cluster
  • Every gear lamp on the selector lit (PRND)
  • Check engine light

How to fix

  1. Photograph the 'Service shifter' message and the gear display so the dealer can see which lamps are lit.

  2. Ask the dealer whether the harness-connection check in FCA bulletin 9003789 was done before the shifter or bezel is replaced.
