PINPOINT TEST 2: THE KEY-IN-IGNITION CHIME IS INOPERATIVE - HYBRID
Normal Operation
The instrument cluster receives the key-in-ignition warning status from the smart junction box (SJB) over the medium speed controller area network (MS-CAN). The key-in-ignition warning switch (part of the ignition switch) is hardwired to the SJB through circuit (L/GY). When the key is inserted into the ignition lock cylinder, the key-in-ignition switch closes and supplies voltage to the SJB. The SJB monitors the door ajar input from the LH front door and the key-in-ignition switch status. When the key is inserted into the ignition lock cylinder and the driver door is open or ajar, the SJB sends the instrument cluster a chime request message to sound the key-in-ignition warning chime.
- DTC B1352 (Ignition Key-In Circuit Failure) - an on-demand DTC that sets if the SJB detects an open on the key-in-ignition switch input, circuit (L/GY) or if the SJB detects ignition START, RUN/START or RUN/ACC inputs without the key-in-ignition input.
Possible Causes
- Wiring, terminals or connectors
- Key-in-ignition switch (part of the ignition switch)
- SJB
- Instrument cluster
Diagnostic Procedure
CAUTION: Use the correct probe adapter(s) when making measurements. Failure to use the correct probe adapter(s) may damage the connector.
