DTC Detecting Condition and Possible Cause
DTC Troubleshooting
NOTE
Before performing steps below, be sure to perform “Body Electrical Control System Check”.

1) Ignition switch OFF.
2) Replace BCM.
3) Repeat BCM Check Flow Table.
DTC U0073 (No. 0073): Control Module Communication Bus OffS6RW0DA204013
Refer to “Troubleshooting for CAN-DTC in Section 1A”.

Refer to “Troubleshooting for CAN-DTC in Section 1A”.
DTC U0101 (No. 0101): Lost Communication with TCMS6RW0DA204018
Refer to “Troubleshooting for CAN-DTC in Section 1A”.
DTC U0155 (No. 0155): Lost Communication with Instrument Panel Cluster (IPC) Control ModuleS6RW0DA204015
Refer to “Troubleshooting for CAN-DTC in Section 1A”.
DTC U1144 (No. 1144): Lost Communication with Keyless Start Control ModuleS6RW0DA204016
Refer to “Troubleshooting for CAN-DTC in Section 1A”. DTC detecting condition Possible cause
Air bag deployment signal is fed from SDM to BCM. • Air bag component parts
• BCM malfunction
Step Action Yes No
1DTC check of SDM
1) Check DTC stored in SDM referring to “DTC Check in
Section 8B”.
Is DTC B1021 detected?Go to “DTC B1021:
Front Air Bag
Deployment Record in
Section 8B”.Substitute a known-
good BCM (included in
junction block) and
recheck.
DTC detecting condition Possible cause
Data write error or check sum error. BCM malfunction
