DTC Description DTC U0100 Gauge control module lost communication with ENG/AT U0104 Gauge Control Module Lost Communication With Driving Support System Control Unit U0122 Gauge control module lost communication with VSA modulator-control unit U0127 Gauge control module lost communication with TPMS control unit U0131 Gauge control module lost communication with EPS Unit U0151 Gauge control module lost communication with SRS unit U1100 Gauge Control Module Lost Communication With Driving Support System Control Unit Are any DTCs indicated?
YES
The failure is duplicated. Go to step 2.
NO
Intermittent failure, the system is OK at this time. Check for poor connections or loose terminals at the transmitting control units and the gauge control module. If the freeze data/on-board snapshot of this DTC is recorded, try to reproduce the failure under the same conditions with the freeze data/on-board snapshot.
- Open wire check (F CAN-H line, F CAN-L line)
-1. Press the engine start/stop button to select the OFF mode.
-2. According to the detected DTC on the following table, disconnect the transmitting control unit connector(s).
DTC Connector U0151 SRS unit connector A (39P) U1100 Multipurpose camera unit 20P connector -3. Check for continuity between the receiving control unit and the transmitting control unit on the F CAN-H circuit and the F CAN-L circuit.

Is there continuity?
YES
The F CAN-H wire and the F CAN-L wire are OK.Refer to the DTC shown on the display, then update, substitute, or replace the control unit based on the instructions (see table).
DTC Operation for transmitting control unit U0100 Check for poor connections or loose terminals at the gauge control module and the PCM. Update the PCM if it does not have the latest software, or substitute a known-good PCM , then recheck. If DTC U0100 goes away and the PCM was updated, troubleshooting is complete. If DTC U0100 goes away and the PCM was substituted, replace the original PCM . U0104U1100 Check for poor connections or loose terminals at the gauge control module and the multipurpose camera unit. Update the multipurpose camera unit if it does not have the latest software, or substitute a known-good multipurpose camera unit , then recheck. If DTC U0104 or U1100 goes away and the multipurpose camera unit was updated, troubleshooting is complete. If DTC U0104 or U1100 goes away and the multipurpose camera unit was substituted, replace the original multipurpose camera unit . U0122 Check for poor connections or loose terminals at the gauge control module and the VSA modulator-control unit. Update the VSA modulator-control unit if it does not have the latest software, or substitute a known-good VSA modulator-control unit , then recheck. If DTC U0122 goes away and the VSA modulator-control unit was updated, troubleshooting is complete. If DTC U0122 goes away and the VSA modulator-control unit was substituted, replace the original VSA modulator-control unit .
