TEST
ACTION
APPLICABILITY
1
Turn the ignition on.
With the DRBIII
t, attempt to communicate with the BCM.
Was the DRBIII
t able to communicate with the BCM?
All
Yes
→ Go To 2
No
→ Refer to the Communication category and perform the appropri-
ate symptom.
Perform VTSS VERIFICATION TEST - 1A.
2
Turn the ignition on.
