16 CHECK POOR CONTACT IN CONNEC-
TORS.
Turn ignition switch to OFF.
17 CHECK VDCCM.
1) Connect all connectors.
2) Erase the memory.
3) Perform inspection mode.
4) Read out the diagnostic trouble code.
18 CHECK ANY OTHER DIAGNOSTIC
TROUBLE CODES APPEARANCE.
Step
Is the voltage less than 1
V?
Is the voltage less than 1
V?
Is there poor contact in
connector between
VDCCM and VDCH/U?
Is the same diagnostic
trouble code as in the cur-
rent diagnosis still being
output?
Are other diagnostic trouble
codes being output?
