ABS (DIAGNOSTICS)
Step
Check
Yes
No
1
CHECK INSTALLATION OF ABSCM&H/U
CONNECTOR.
1) Turn the ignition switch to OFF.
2) Check that the ABSCM&H/U connector is
inserted to ABSCM&H/U until the clamp locks
onto it.
Is the connector firmly
inserted?
Go to step 2.
Insert the
ABSCM&H/U con-
nector until the
clamp locks com-
pletely.
2
READ DTC.
Read the DTC. <Ref. to ABS(diag)-18, Read
Diagnostic Trouble Code (DTC).>
Is DTC displayed?
Perform the diag-
nosis according to
DTC.
Go to step 3.
3
CHECK BRAKE FLUID AMOUNT.
Check the amount of brake fluid in the reservoir
tank of the 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.
4
CHECK BRAKE FLUID LEVEL SWITCH.
1) Disconnect the level switch connector (B16)
from master cylinder.
2) Measure the resistance of master cylinder
terminals.
Terminals
No. 1 — No. 2:
Is the resistance 1 M
: or
more?
Go to step 5.
Replace the mas-
ter cylinder.
5
CHECK PARKING BRAKE SWITCH.
1) Disconnect the connector (B404) from park-
ing brake switch.
2) Release the parking brake.
3) Measure the resistance between parking
brake switch terminal and chassis ground.
Is the resistance 1 M
: or
more?
Go to step 6.
Replace the park-
ing brake switch.
6
CHECK GROUND SHORT OF HARNESS.
1) Disconnect the connectors (i10 and i11)
from the combination meter.
2) Measure the resistance between combina-
tion meter connector and chassis ground.
Connector & terminal
Model with the normal meter
(i10) No. 8 — Chassis ground:
(i11) No. 10 — Chassis ground:
Model with the meter with MID
(i10) No. 8 — Chassis ground:
(i10) No. 4 — Chassis ground:
Is the resistance 1 M
: or
more?
Go to step 7.
Repair the harness
connector between
combination meter
and parking brake
switch.
7
CHECK HARNESS.
1) Disconnect the connector (B301) from the
ABSCM&H/U.
2) Disconnect the connector (i10) from the
combination meter.
3) Measure the resistance between the
ABSCM&H/U connector and combination
meter connector.
Connector & terminal
(B301) No. 8 — (i10) No. 7:
Is the resistance less than 0.5
:? Go to step 8.
Repair the harness
between the
ABSCM&H/U and
the combination
meter.
8
CHECK POOR CONTACT IN CONNECTOR.
Check for poor contact in all connectors.
Is there poor contact?
Repair the connec-
tor.
Go to step 9.
9
CHECK ABSCM.
1) Connect the connector to the ABSCM&H/U.
2) Turn the ignition switch to ON.
3) Measure the resistance between combina-
tion meter connector and chassis ground.
Connector & terminal
(i10) No. 7 — Chassis ground:
Is the resistance less than 0.5
:? Check the combi-
nation meter.
Replace the
ABSCM only. <Ref.
