THEFT-DETERRENT CONTROL MODULE INSPECTION

id091400820900

1. Remove the following parts:

  (1) Dashboard under cover (Passenger side) (See DASHBOARD UNDER COVER REMOVAL/INSTALLATION.)

  (2) Glove compartment (See GLOVE COMPARTMENT REMOVAL/INSTALLATION.)

2. Measure the voltage according to the terminal voltage table.

  • If the voltages cannot be verified as indicated in the terminal voltage table, inspect the parts under “Inspection item(s)”.
    ― If the system does not work normally even though the inspection items or related wiring harnesses do not have any malfunction, replace the theft-deterrent control module.
