Key Interlock System: Ignition Key Cannot Be Moved From Acc To Lock Position With Shift Lever In Park Position: Odyssey

Turn ignition off. Disconnect 7-pin key interlock switch harness connector, located near lower steering column.
Connect interlock switch harness connector terminal No. 7 (White/Yellow wire) to battery positive terminal. Connect harness connector terminal No. 5 (White/Red wire) to battery negative terminal. See WIRING DIAGRAMS . Turn ignition switch to ACC position. Push in on ignition key. A clicking sound should be heard from key interlock solenoid. If interlock solenoid operates properly, go to next step. If interlock solenoid does not operate properly, replace ignition key cylinder/steering lock assembly.
Check voltage between body ground and interlock switch harness connector terminal No. 7 (White/Yellow wire). If battery voltage is present, go to next step. If battery voltage is not present, check for blown fuse No. 47 (20-amp) in underhood fuse/relay box. Replace as necessary. If fuse is okay, repair open in circuit between ignition switch harness connector No. 7 (White/Yellow wire) and underhood fuse/relay box. See WIRING DIAGRAMS .
Disconnect parking pin switch harness connector. Parking pin switch is located on front side of shift lever. Place gear shift lever in Park and pulled toward driver. Check continuity between parking pin switch harness connector terminals No. 1 (Black wire) and No. 3 (White/Red wire). If continuity exists, go to next step. If continuity does not exist, check for open in circuit between parking pin switch and 3-pin harness connector. Repair as necessary. If circuit is okay, replace parking pin switch.
Check continuity between parking pin switch harness connector terminal No. 5 (White/Red wire) and interlock switch harness connector terminal No. 3 (White/Red wire). If continuity exists, go to next step. If continuity does not exist, repair open in circuit between parking pin switch and interlock switch connector.
Check continuity between body ground and parking pin switch harness connector terminal No. 1 (Black wire). If continuity exists, go to next step. If continuity does not exist, repair open in circuit between parking pin harness connector terminal No. 1 (Black wire) and ground connector. See WIRING DIAGRAMS .
Check for loose key interlock switch connector and parking pin switch connector. Repair as necessary. If connectors are okay, substitute with a known-good steering lock assembly and recheck system. If symptom or problem foes away, replace steering lock assembly.
