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 Procedure

INFOID:0000000009693651

1.

 PERFORM SELF DIAGNOSTIC RESULT

1. Turn ignition switch ON and wait for 2 second or more.

2. Check “SELF- DIAG RESULTS”.
Is “CAN COMM CIRCUIT” displayed?

YES

>> Perform CAN Diagnosis as described in DIAGNOSIS section of CONSULT Operation Manual.

NO

>> Refer to 

GI-41, "Intermittent Incident"

.
