IDM Input Circuit Malfunction/ Ignition Coil Control Circuit High Voltage

Severity

Medium

Can I keep driving?

Usually drivable, but get it diagnosed without delay.

First step

With the coil unplugged and the ignition off, measure resistance from the control wire to ground to confirm the short

What does it mean?

P1360 is a Powertrain (engine, transmission, fuel system) fault code. It indicates: Cylinder 2 Ignition Circuit Short to Ground .

Symptoms

  • Cylinder 2 misfires heavily or drops out entirely, shaking the engine at idle
  • Check engine light on, flashing when the misfire is severe
  • Noticeable power loss and hesitation when accelerating
  • Fuel odour from the exhaust and elevated fuel consumption
  • Rough idle that may worsen after driving through water or washing the engine bay

Likely causes

  • Chafed control wire grounding against the cylinder head, valve cover or a mounting bracket
  • Coil for cylinder 2 with an internal short between the primary winding and the coil body
  • Oil or water in the coil well shorting the connector pins to ground
  • Melted harness section close to the exhaust system
  • Terminal displaced in the connector and touching a grounded surface
  • Damaged harness clip letting the loom rest on a sharp metal edge
  • Module coil driver damaged by the continuous ground fault

How to fix it

  1. With the coil unplugged and the ignition off, measure resistance from the control wire to ground to confirm the short
  2. Inspect the coil well, boot and connector for oil and moisture, and dry the area completely
  3. Test the cylinder 2 coil between its control terminal and the coil body to detect an internal short
  4. Follow the harness from the coil to the module, checking clips, brackets and any section near heat
  5. Repair the damaged insulation properly and re-secure the loom clear of sharp edges and hot parts
  6. Verify with a scope or test light that the control line switches normally after the repair
  7. Replace the coil if it is internally shorted, and only assess the module after the circuit is confirmed clean
