CONSULT-II Functions (IPDM E/R)AKS007I6
CONSULT-II can display each diagnostic item using the diagnostic test mode shown following.
CONSULT-II BASIC OPERATION
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. With ignition switch OFF, connect CONSULT-II and CONSULT-II CONVERTER to data link connector, then turn ignition switch
ON.
2. Touch “START (NISSAN BASED VHCL)”.
3. Touch “IPDM E/R” on “SELECT SYSTEM” screen. If “IPDM E/R” is not displayed, refer to GI-39, "
CONSULT-II Data
Link Connector (DLC) Circuit" .
Check Item, Diagnosis Mode Description
SELF-DIAGNOSTIC RESULTS Refer to PG-21, "
SELF-DIAG RESULTS" .
DATA MONITOR The input/output data of IPDM E/R is displayed in real time.
CAN DIAG SUPPORT MNTR The result of transmit/receive diagnosis of CAN communication can be read.
ACTIVE TEST IPDM E/R sends a drive signal to electronic components to check their operation.

Optical sensor System InspectionAKS007F5
1. CHECK OPTICAL SENSOR INPUT SIGNAL
With CONSULT-II
Select “BCM” on CONSULT-II. With “HEAD LAMP” data monitor,
make sure “OPTICAL SENSOR”, check difference in the voltage

optical sensor is insufficiently illuminated, the measured value
may not satisfy the standard.
Without CONSULT-II
1. Turn ignition switch ON.
2. Check voltage between BCM harness connector M3 terminal 14 (P) and ground.
CAUTION:
Optical sensor must be securely subjected to work lamp light. If
optical sensor is insufficiently illuminated, the measured value
may not satisfy the standard.
