DTC B2013 STRG COMM 1NIS001YN
DIAGNOSIS DESCRIPTION
B2013 steering lock communication malfunction monitors the communication condition between Intelligent
Key unit and steering lock unit. If the reply from the steering lock unit against the communication from Intelli-
gent Key unit does not come twice continuously, Intelligent Key unit judges that it is the malfunction and dis-
plays the DTC (Diagnostic Trouble Code).
TERMINALS AND REFERENCE VALUE FOR INTELLIGENT KEY UNIT
SELF-DIAGNOSTIC LOGIC
DIAGNOSTIC PROCEDURE
1. CHECK STEERING LOCK UNIT POWER SUPPLY
1. Turn ignition switch OFF.
2. Disconnect steering lock unit connector.
3. Check voltage between steering lock unit connector and ground.
OK or NG
OK >> GO TO 3.
NG >> GO TO 2.
