Go To Next Step.
3.INSPECT COMMUNICATION FUNCTION OF LARGE-SCALE MULTIPLEX
COMMUNICATION SYSTEM (BEAN)
a. Use the hand-held tester to check for normal function of the multiplex communication system.
1. (ECU not connected, communication line malfunctioning) Without code outputs, proceed to
A.
2. (ECU not connected, communication line malfunctioning) With code outputs, proceed to B.
B: Go to MULTIPLEX COMMUNICATION SECTION (SEE DIAGNOSTIC TROUBLE CODE
CHART )
A: Go to Next Step.
4.CHECK FOR DTC
a. Check for DTCs and note any codes that are output.
b. Delete the DTC.
c. Recheck for DTCs. Try to prompt the DTC by simulating the original activity that the DTC
suggests.
1. If the DTC does not reoccur, proceed to A
2. If the DTC reoccur, proceed to B
B: Go to step 6
A: Go to Next step
