What this code means

Common causes

  • Electric A/C compressor failure
  • Thermal storage evaporator issue
  • Auxiliary coolant pump fault
  • Electric heater element failure
  • Control module communication error

Diagnostic steps

  1. Check auxiliary A/C compressor operation during engine stop
  2. Monitor cabin temperature drift rate
  3. Test auxiliary coolant pump
  4. Check electric heater circuit
  5. Monitor start-stop inhibit reasons

Repair notes

Replace auxiliary A/C compressor or electric heater. Repair auxiliary coolant pump if cabin heating affected.

⚠ STILL BEHIND THE PAYWALL
The 2016 Honda Pilot repair data is incomplete because no one has sponsored it yet. For $99, we generate the full step-by-step procedures, then fact-check them with a second AI pass and your expert review. Your name on every procedure, permanently.
The same data would cost $169/mo from Mitchell1 or $30/year from ALLDATAdiy — and you'd be renting access, not freeing it. Sponsor once, free forever.
