 (CONSULT indication)

DTC detection condition

Inspection/Action

U0101

LOST COMM (TCM)

When ECM is not transmitting or receiving CAN commu-
nication signal of OBD (emission-related diagnosis) from 
TCM for 2 seconds or more.

Refer to 

LAN-36

.

U0140

LOST COMM (BCM)

When ECM is not transmitting or receiving CAN commu-
nication signal of OBD (emission-related diagnosis) from 
BCM for 2 seconds or more.

U0164

LOST COMM (HVAC)

When ECM is not transmitting or receiving CAN commu-
nication signal of OBD (emission-related diagnosis) from 
front air control or unified meter and A/C amp. for 2 sec-
onds or more.

U1000

CAN COMM CIRCUIT

ECM

When ECM is not transmitting or receiving 
CAN communication signal of OBD (emission-
related diagnosis) for 2 seconds or more.

Except 
for ECM

When a control unit (except for ECM) is not 
transmitting or receiving CAN communication 
signal for 2 seconds or more.

U1001

CAN COMM CIRCUIT

When ECM is not transmitting or receiving CAN commu-
nication signal other than OBD (emission-related diagno-
sis) for 2 seconds or more.

U1002

SYSTEM COMM

When a control unit is not transmitting or receiving CAN 
communication signal for 2 seconds or less.

Start the inspection. Refer
