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 
to the applicable section 
of the indicated control 
unit.

U1010

CONTROL UNIT(CAN)

When an error is detected during the initial diagnosis for
