Shift Interlock Switch: Testing and Inspection




Park Pin Switch Test

1. Connect the HDS to the DLC (A).





2. Check the Park Pin Switch signal with the HDS in the A/T data list while the shift lever is in P, and when the shift lever is moved to any position other than P.

NOTE: If the HDS does not communicate with the PCM, troubleshoot the DLC circuit Testing and Inspection.

3. Check that the park pin switch signal is OFF while the shift lever is in P, and signal is ON when the shift lever is moved out of P.

4. If the park pin switch signal is OK, test is complete, disconnect the HDS. If the signal is incorrect, go to step 5, and test the switch signal at the park pin switch/A/T gear position indicator panel light connector.

5. Remove the driver's dashboard lower cover Dashboard Center Lower Cover Disassembly/Reassembly.

6. Remove the steering column covers.

7. Disconnect the D3 switch/shift lock solenoid/park pin switch connector.





8. Move the shift lever into P, then check for continuity between D3 switch/shift lock solenoid/park pin switch connector terminals No. 1 and No. 2. There should be no continuity.

9. Move the shift lever out of P, and check for continuity between terminals No. 1 and No. 2. There should be continuity.

10. If the park pin switch tests OK, check for an open or short in park pin switch wires.

If the park pin switch does not perform as specified, do the shift lock troubleshooting A/T Interlock System - Shift Lock System Circuit Troubleshooting, if the circuit is OK, replace the park pin switch Service and Repair.
