Is the resistance less than 0.5
Ω
?
Go to step 3.
Repair the
VDCCM&H/U
ground harness.
3
CHECK POOR CONTACT IN CONNECTORS. Is there poor contact in con-
nector between generator, bat-
tery and VDCCM&H/U?
Repair the con-
nector.
Go to step 4.

1) Connect all the connectors.
2) Erase the memory.
3) Perform the inspection mode.
4) Read the DTC.
Is the same DTC displayed?
Replace the
