STEERING LOCK UNIT INSPECTION [ADVANCED KEYLESS SYSTEM]
- Remove the column cover. (See «COLUMN COVER REMOVAL/INSTALLATION»(ref-244480-S03023275402006092400000) .)
- Measure the voltage at each terminal (other than terminals G and H). If the voltage is not as specified in the «Terminal Voltage Table (Reference)»(ref-244461-S39986085832006092400000) , inspect the parts under "Inspection item(s)".
- Disconnect the steering lock unit connector
- Verify that continuity at terminals G and H is as indicated in the «Terminal Voltage Table (Reference)»(ref-244461-S39986085832006092400000) . 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 panel light control switch.
