NOTE:
*: Perform “ACTIVE TEST” with CONSULT-II. Refer to DI-91, "
ACTIVE TEST" .
CONSULT-II Function (LDW)NKS003VM
DESCRIPTION
CONSULT-II can display each diagnostic item using the diagnostic test modes 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 the ignition switch OFF, connect CONSULT-II and CON-
SULT-II CONVERTER to the data link connector, and then turn
ignition switch ON.
