Work FlowEIS002UU
1. Check the symptom and customer's requests.
2. Understand the outline of system. Refer to GW-15, "
System Description" .
3. According to the trouble diagnosis chart, repair or replace the cause of the malfunction.
Refer to GW-36, "
Trouble Diagnoses Symptom Chart" .
4. Does power window system operate normally? Yes, GO TO 5, If No, GO TO 3.
5. INSPECTION END.
CONSULT-II Function (BCM)EIS002UV
CONSULT-II can display each diagnostic item using the diagnostic test modes shown following.
CONSULT-II INSPECTION PROCEDURE
CAUTION:
If CONSULT-II is used with no connection of CONSULT-II CONVERTER, malfunctions might be
detected in self-diagnosis depending on control unit which carry out CAN communication.
1. Connect CONSULT-II and CONSULT-II CONVERTER to the
data link connector.
2. Turn ignition switch ON.
3. Touch “START (NISSAN BASED VHCL)”.
BCM diagnostic
test itemDiagnostic mode Content
Inspection by partWORK SUPPORT Changes setting of each function.
DATA MONITOR Displays BCM input/output data in real time.
ACTIVE TEST Operation of electrical loads can be checked by sending drive signal to them.
SELF-DIAG RESULTS Displays BCM self-diagnosis results.
CAN DIAG SUPPORT MNTR The results of transmit/receive diagnosis of CAN communication can be read.
ECU PART NUMBER BCM part number can be read.
CONFIGURATION Performs BCM configuration read/write functions.
