DTC Detection Condition	U000188 Module communication error (HS-CAN) U010000 Communication error with ECM U010100 Communication error with TCM U012100 Communication error with brake actuator U015100 Communication error with center airbag sensor assembly U015500 Communication error with combination meter U021400 Communication error with engine stop and start ECU
DTC Detection Condition	U000188 Main body ECU detects the CAN bus communication line (HS-CAN) malfunction 10 times continuously with the ignition switched ON (engine off or on). U010000 Main body ECU could not receive the CAN signal from the ECM for 5 s or more with the ignition switched ON (engine off or on). U010100 Main body ECU could not receive the CAN signal from the TCM for 5 s or more with the ignition switched ON (engine off or on). U012100 Main body ECU could not receive the CAN signal from the brake actuator for 5 s or more with the ignition switched ON (engine off or on). U015100 Main body ECU could not receive the CAN signal from the center airbag sensor assembly for 5 s or more with the ignition switched ON (engine off or on). U015500 Main body ECU could not receive the CAN signal from the combination meter for 5 s or more with the ignition switched ON (engine off or on). U021400 Main body ECU could not receive the CAN signal from the engine stop and start ECU for 5 s or more with the ignition switched ON (engine off or on).
Fail-safe Operation	U000188 Exterior lighting system Turn the TNS (Parking Lights) and headlights LO on, and turn off other exterior light controls. Interior light control system Continue the controls prior to the interior light malfunction detection for 5 s and turn the light on using the initial value after 5 s have elapsed. Front washer system Stop the front washer control. Blower system Main body ECU power supply condition is on: Turn the blower relay on. Main body ECU power supply condition is off: Turn the blower relay off. U010000 Not applicable U010100 Not applicable U012100 Not applicable U015100 Not applicable U015500 Interior light control system Continue the controls prior to the interior light malfunction detection for 5 s and turn the light on using the initial value after 5 s have elapsed. Blower system Main body ECU power supply condition is on: Turn the blower relay on. Main body ECU power supply condition is off: Turn the blower relay off. U021400 Exterior lighting system Turn the TNS (Parking Lights) and headlights LO on, and turn off other exterior light controls. Windshield wiper system Continue the controls prior to the windshield wiper malfunction detection. Front washer system Stop the front washer control.
