|DTC Code||DTC Name|
|U0100||Lost Communication with ECM / PCM|
|U0155||Lost Communication with Combination Meter|
These DTCs are stored when there is a CAN communication error between the certification ECU (smart key ECU assembly), ECM or combination meter assembly.
When the cable is disconnected and reconnected to the negative (-) battery terminal, the power source mode returns to the state it was in before the cable was disconnected.
|DTC No.||Detection Item||DTC Detection Condition||Trouble Area||Note|
|U0100||Lost Communication with ECM / PCM||CAN communication error between the certification ECU (smart key ECU assembly) and ECM (1-trip detection logic*)||ECM||Turn the engine switch on (IG) and wait 10 seconds or more.|
|U0155||Lost Communication with Combination Meter||CAN communication error between the certification ECU (smart key ECU assembly) and combination meter assembly (1-trip detection logic*)||Combination meter assembly||Turn the engine switch on (IG) and wait 10 seconds or more.|
*: Only detected while a malfunction is present and the engine switch is on (IG).
|DTC No.||Vehicle Condition when Malfunction Detected||Fail-safe Function when Malfunction Detected|
|U0100||There is no effect on vehicle behavior.||
If the following conditions are met, it is determined that the malfunction is not in the direct line (NE) but in CAN communication.
If the following conditions are met, it is determined that there is a malfunction in both CAN communication and the direct line (NE).
|U0155||The warning (meter buzzer) does not sound and the meter does not indicate a warning.||-|

CAUTION / NOTICE / HINT
When using the GTS with the engine switch off, connect the GTS to the DLC3 and turn a courtesy light switch on and off at intervals of 1.5 seconds or less until communication between the GTS and the vehicle begins. Then select the Model Code "KEY REGIST" under manual mode and enter the following menus: Body Electrical / Entry&Start(CAN). While using the GTS, periodically turn a courtesy light switch on and off at intervals of 1.5 seconds or less to maintain communication between the GTS and the vehicle.
After performing repairs, perform the operation that fulfills the DTC output confirmation operation, and then confirm that no DTCs are output again.
