DTC DETECTION LOGIC
NOTE:
U1000 can be set if a module harness was disconnected and reconnected, perhaps during a repair. Confirm
that there are actual CAN diagnostic symptoms and a present DTC by performing the Self Diagnostic Result
procedure.
Diagnosis ProcedureINFOID:0000000012430178
1. PERFORM SELF DIAGNOSTIC RESULT
1. Turn ignition switch ON and wait for 2 second or more.
2. Check “Self Diagnostic Result” of “BCM” using CONSULT.
Is
“CAN COMM CIRCUIT” displayed?
YES >> Perform CAN Diagnosis as described in DI AGNOSIS section of CONSULT Operation Manual.
NO >> Refer to GI-42, "
Intermittent Incident".
CONSULT Display DTC Detection Condition Possible Cause
CAN COMM CIRCUIT
[U1000] When any listed module cannot communicate
with CAN communication signal continuously for
2 seconds or more with ignition switch ON In CAN communication system, any item (or
items) of the following listed below is malfunc-
tioning.
•Transmission
• Receiving (ECM)
• Receiving (VDC/TCS/ABS)
• Receiving (METER/M&A)
