Items to check

  1. Inspect DTC code.
  2. Inspect whether N setting matches.
  • Adjust N setting (refer to automatic transmission system - "inhibitor switch")
  1. Inspect shift cable separation.
  • Adjust shift cable separation (refer to automatic transmission system - "shift cable")
  1. Inspect whether connector is connected.
  • Inspect connector thoroughly for looseness, poor connection, bending, corrosion, contamination, deformation, or damage.
  • Turn ignition key "ON" and engine "OFF" and measure the power supplied to inhibitor switch circuit and voltage between ground.

Specification : approx. 12 V

  • F i x the pin wiring when connector pin wiring is faulty (refer to ETM - "wiring repair").
  1. Inspect ground condition on reversing light circuit.
  • Check the ground location of reversing light (refer to ETM - "harness location map").
  • Reattach reversing light if ground condition is faulty.
  1. Inspect wiring connection on junction box power terminal and fuse lamp.
  • Check whether fuse holder is separated and holder is holding the fuse tight.

  • Attach tester fuse to check if it is connected appropriately.

  • Check whether fuse capacity is appropriate for each circuit.
  • Check if fuse is damaged.
  • Check pulling of fuse fixing wiring, inflow of foreign substance, and arrangement condition of terminal.
  • Relocate the terminal that has been pulled and inspect using the method explained above.
  • When problem is not solved, refer to the circuit diagram wiring repair instructions to fix or replace the terminal.
  1. Inspect inhibitor switch signal.
  • Turn ignition key "ON" and engine "OFF".
  • Measure the voltage between each terminal and chassis ground when shifting lever to "P. R. N, D" range.
