ACTIVE TEST
CAUTION:
During vehicle driving, do not perform active test.
NOTE:
If active test is performed, reset seat memory and automatic drive positioner seat memory after performing
work.
DISPLAY ITEM LIST
CAN Communication Inspection Using CONSULT-II (Self-Diagnosis)EIS004XP
1. SELF-DIAGNOSTIC RESULT CHECK
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 carries out CAN communication.
1. Connect to CONSULT-II, and select “AUTO DRIVE POS.” on the “SELECT DIAG SYSTEM ” screen.
2. Select “SELF-DIAG RESULTS ” on "SELECT DIAG MODE" screen.
3. Check display content in self-diagnostic results.
