10.Warning Light Illumination Pattern
A: INSPECTION
1) When warning lights or indicator lights do not illuminate in accordance with this illumination pattern, there
must be an electrical malfunction.
2) When warning lights or indicator lights remain constantly OFF, check the combination meter circuit or CAN
communication circuit.

ness connector
between combina-
tion meter brake
fluid level switch
and parking brake
switch.

meter connector.
Connector & terminal
(B310) No. 3 — (i11) No. B8:
Is the resistance less than 0.5
Ω?
Go to step 8.Repair the har-
ness connector
between
VDCCM&H/U and
combination
meter.
8CHECK POOR CONTACT IN CONNECTOR.
Check poor contact in all connectors.
Is there poor contact? Repair the con-
nector.
Go to step 9.
9CHECK VDCCM.
1) Connect the connector (B310) to
VDCCM&H/U.
2) Turn the ignition to ON.
