1. Remove the column cover. (See COLUMN COVER REMOVAL/INSTALLATION.)
2. Measure the voltage at each terminal.
If the voltage is not as specified in the Terminal Voltage Table (Reference), inspect the parts under “Inspection item(s)”.
If there is any malfunction, inspect the parts under “Inspection item(s)”.
If the system does not work properly even though the parts or related wiring harnesses do not have any malfunction, replace the steering lock unit.
