Shift Interlock Systems: Diagnosis Honda Odyssey II

Control Unit Input Test

SRS components are located in this area. Review the SRS component locations , and the precautions and procedures in appropriate AIR BAG article under RESTRAINTS before performing repairs or service.

Scheme 466

Scheme 467

1. Disconnect the 22P connector from the multiplex control unit, driver's, then remove the control unit from the driver's under-dash fuse/relay box.
2. Inspect the connectors and connector terminals to be sure they are all making good contact. If the terminals are bent, loose, or corroded, repair them as necessary, and recheck the system. If the terminals look OK, go to step 3.
3. With the control unit still disconnected from its connectors and the fuse/relay box, make these input tests. If a test indicates a problem, find and correct the cause, then recheck the system. If all the input tests prove OK, go to step 4. (Scheme 467): Testing Multiplex Control Unit, Driver's, Connector A (24P) (Scheme 468): Testing Multiplex Control Unit, Driver's, Connector B (22P)
4. Reconnect the connectors to the multiplex control unit, and make this input test.

Scheme 468

1. If a test indicates a problem, find and correct the cause, then recheck the system.
2. If all the input tests prove OK, substitute a known-good multiplex control unit, and recheck the system. If the system is OK, the multiplex control unit must be faulty; replace it. (Scheme 469): Testing Multiplex Control Unit

Key Interlock Solenoid/Switch Test

SRS components are located in this area. Review the SRS component locations , and the precautions and procedures in appropriate AIR BAG article under RESTRAINTS before performing repairs or service.

Scheme 469

1. Remove the steering lower cover (see Steering Column Removal & Installation ).
2. Disconnect the key switch connector (7P) from the steering lock assembly.
3. Check for continuity between the No. 5 and No. 7 terminals when the key is pushed, and check for no continuity when the key is released. (Scheme 470): Check For Continuity Between No. 5 & No. 7 Terminals Of Key Switch Connector (7P)
4. Check that the key cannot be removed with power connected to the No. 7 terminal and ground connected to the No. 3 terminals. If the key cannot be removed, the key interlock solenoid is OK. If the key can be removed, replace the steering lock assembly (the key interlock solenoid is not available separately).

Shift Lock Solenoid Test

SRS components are located in this area. Review the SRS component locations , and the precautions and procedures in appropriate AIR BAG article under RESTRAINTS before performing repairs or service.

Scheme 470

1. Remove the steering column upper cover (see Steering Column Removal & Installation ).
2. Disconnect the shift lock solenoid 2P connector. see scheme 23: Disconnecting Shift Lock Solenoid 2P Connector
3. Connect the No. 1 terminal of the shift lock solenoid connector to the battery positive terminal, and connect the No. 2 terminal to the battery negative terminal.
4. Check that the shift lever can be moved from the P position. Release the battery terminals from the shift lock solenoid connector. Move the shift lever back to the P position, and make sure it locks.
5. Check that the shift lock releases when the release lever is pushed, and check that it locks when the release lever is released.
6. If the solenoid does not work, replace it.

Park Pin Switch Test

SRS components are located in this area. Review the SRS component locations , and the precautions and procedures in appropriate AIR BAG article under RESTRAINTS before performing repairs or service.

Scheme 471

1. Remove the steering column covers (see Steering Column Removal & Installation ).
2. Disconnect the park pin switch connector.
3. Shift the shift lever into the P position, then check for continuity between the No. 1 and No. 3 terminals. There should be no continuity. see scheme 27: Checking For Continuity Between No. 1 & No. 3 Terminals Of Park Pin Switch Connector
4. Shift the shift lever out of the P position, and check for continuity between the terminals in step 3. There should be continuity.
5. If the park pin switch is faulty, replace the control bracket assembly. (The park pin switch is not available separately.)
