Key Interlock Solenoid/Switch Test

SRS components are located in this area. Review the SRS component locations (see COMPONENT LOCATION INDEX ), and the precautions and procedures (see PRECAUTIONS AND PROCEDURES ) before performing repairs or service.

  1. Remove the driver's dashboard lower cover (see INSTRUMENT PANEL 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.

  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).
