Step Check Yes No
1CHECK INSTALLATION OF VDCCM&H/U
CONNECTOR.
1) Turn the ignition switch to OFF.
2) Check that the VDCCM&H/U connector is
inserted until it is locked by clamp.
Is the connector firmly
inserted?
Go to step 2.Insert the
VDCCM&H/U con-
nector until it is
locked by clamp.
2READ DTC.
Read the DTC. Diagnostic Trouble Code (DTC).>
Is DTC displayed? Perform the diag-
nosis according to
DTC.
Go to step 3.
3CHECK BRAKE FLUID AMOUNT.
Check the amount of brake fluid in the reser-
voir tank of master cylinder.
Is the amount of brake fluid
between the lines of “MAX”
and “MIN”?
Go to step 4.Replenish brake
fluid to the speci-
fied value.
4CHECK BRAKE FLUID LEVEL SWITCH.
1) Turn the ignition switch to OFF.
2) Disconnect the level switch connector (B16)
from master cylinder.
3) Measure the resistance of master cylinder
terminals.
Te r m i n a l s
No. 1 — No. 2:
Is the resistance more than 1
MΩ?
Go to step 5.Replace the mas-
ter cylinder.
5CHECK PARKING BRAKE SWITCH.
1) Disconnect the connector (B404) from
parking brake switch.
2) Release the parking brake.
3) Measure the resistance between parking
brake switch terminal and chassis ground.
Is the resistance more than 1
MΩ?
Go to step 6.Replace the park-
ing brake switch.
6CHECK GROUND SHORT OF HARNESS.
1) Disconnect the connector (i11) from combi-
nation meter.
2) Measure the resistance between combina-
tion meter connector and chassis ground.
Connector & terminal
(i11) No. B8 — Chassis ground:
Is the resistance more than 1
MΩ?
Go to step 7.Repair the har-
ness connector
between combina-
tion meter brake
fluid level switch
and parking brake
switch.
7CHECK HARNESS CONNECTOR.
1) Disconnect the connector (B310) from the
VDCCM&H/U.
2) Disconnect the connector (i11) from combi-
nation meter.
3) Measure the resistance between
VDCCM&H/U connector and combination
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.
3) Measure the resistance between combina-
tion meter connector and chassis ground.
Connector & terminal
(i11) No. B8 — Chassis ground:
Is the resistance less than 0.5
Ω?
Check the combi-
nation meter.
Replace the
VDCCM&H/U.
