4. Confirm the unit name that “UNKWN” is displayed on the copy of “CAN DIAG SUPPORT MNTR” screen
of “INTELLIGENT KEY”, “METER A/C AMP”, “MULTI AV”, “ABS” and “IPDM E/R” as well as “ENGINE”.
And then, put a check mark to the check sheet table.
NOTE:
For “INTELLIGENT KEY”, “UNKWN” is displayed on “ECM”, “BCM/SEC” and “TCM”. Put a check mark
to it.
For “METER A/C AMP”, “UNKWN” is displayed on “ECM”, “TCM” and “BCM/SEC”. Put a check mark to
it.
For “MULTI AV”, “UNKWN” is displayed on “ECM” and “BCM/SEC”. Put a check mark to it.
For “ABS”, “UNKWN” is displayed on “ECM”, “TCM”, “METER/M&A”, “ICC” and “AWD/4WD”. But put a
check mark to “ECM” and “TCM” because “UNKWN” is listed on the column of reception diagnosis of
the check sheet table.
For “IPDM E/R”, “UNKWN” is displayed on “ECM” and “BCM/SEC”. Put a check mark to it.
