Inspection flow

Items to check

1. Inspect DTC code.
2. Inspect whether N setting matches.

• Adjust N setting (refer to automatic transmission system - "inhibitor switch")

3. Inspect shift cable separation.

• Adjust shift cable separation (refer to automatic transmission system - "shift cable")

4. 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").

5. 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.

6. 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.

7. 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.
