The Communication Line Check
Ending the self-diagnostic function
TYPE S model Error Code ListError code Type of communication line(s) error
Except TYPE S model Error Code List Error code Type of communication line(s) error
Example Indication
22-243
Normal (all segments come on.): Faulty (Error 1):
Fault (Error 13): Fault (Error 123):
While in the self-diagnostic mode, the Communication Line Check starts after the LCD Segments Check.
If all segments come on, the communication line is OK. If faulty, the word ‘‘Error’’ will be indicated on the odometer
display followed by number(s).
Error 1 F-CAN communication
Error 2 B-CAN communication
Error 12 F-CAN and B-CAN communication
Error 1 F-CAN communication
Error 2 B-CAN communication
Error 3 UART communication
Error 12 F-CAN and B-CAN communication
Error 13 F-CAN and UART communication
Error 23 B-CAN and UART communication
Error 123 F-CAN, B-CAN and UART communication
If the word ‘‘Error 1’’ is indicated, there is a malfunction in the communication line between the gauge control module (tach) and the fast-controller area network (F-CAN). Check for DTCs in the ECM/PCM and troubleshoot any
DTCs found. If no DTCs are found, go to indicated troubleshooting.
If the word ‘‘Error 2’’ is indicated, there is a malfunction in the communication line between the gauge control module (tach) and the body-controller area network (B-CAN). Go to indicated troubleshooting (B 1155 to B1160).
Except TYPE S model: If the word ‘‘Error 3’’ is indicated, there is a malfunction in the UART communication line between the gauge control module (tach) and the gauge control module (speedo). Go to the gauge control module
(tach) input test and check terminal No. 20. If the wire harness is OK, substitute a known-good gauge control module
(speedo) and recheck.
If any F-CAN or B-CAN communication line errors are found, go to DTC check using HDS.
Turn the ignition switch to LOCK (0).
NOTE: If the vehicle speed exceeds 2 km/h (1.2 mph), the self-diagnostic function ends.
