Diagnostic Procedure with Diagnostic Trouble Code (DTC)
Step
1 CONFIRM VEHICLE TYPE.
2 CHECK HARNESS CONNECTOR BETWEEN
ABSCM AND DRIVER'S CONTROL CENTER
DIFFERENTIAL CONTROL MODULE.
1) Turn the ignition switch to ON.
2) Disconnect the connector from ABSCM and
driver's control center differential control mod-
ule.
3) Measure the resistance of harness connec-
tors between ABSCM and driver's control cen-
ter differential control module.
Connector & terminal
(B301) No. 26 — (B380) No. 18:
(B301) No. 11 — (B380) No. 24:
3 CHECK GROUND SHORT OF THE HAR-
NESS CONNECTOR BETWEEN ABSCM
AND DRIVER'S CONTROL CENTER DIFFER-
ENTIAL CONTROL MODULE.
Measure the resistance between ABSCM con-
nector and chassis ground.

(B301) No. 26 — Chassis ground:
(B301) No. 11 — Chassis ground:
4 CHECK BATTERY SHORT OF THE HAR-
NESS CONNECTOR BETWEEN ABSCM
AND DRIVER'S CONTROL CENTER DIFFER-
ENTIAL CONTROL MODULE.
1) Turn the ignition switch to ON.
2) Measure the voltage between ABSCM con-
nector and chassis ground.
Connector & terminal
(B301) No. 26 — Chassis ground:
(B301) No. 11 — Chassis ground:
5 CHECK ABSCM.
1) Turn the ignition switch to OFF.
2) Connect the connector to ABSCM.
3) Measure the resistance between the
driver's control center differential control mod-
ule terminals.
Connector & terminal
(B380) No. 18 — (B380) No. 24:
6 CHECK POOR CONTACT OF ABSCM CON-
NECTORS.
7 CHECK DRIVER'S CONTROL CENTER DIF-
FERENTIAL CONTROL MODULE.
1) Connect the driver's control center differen-
tial control module to connector.
2) Disconnect the connectors from ABSCM.
3) Measure the resistance between ABSCM
connector terminals.
Connector & terminal
(B301) No. 11 — (B301) No. 26:
Check
Is the vehicle STI model?
Is resistance less than 0.5 Ω?
Is the resistance 1 MΩ or
more?
Is the voltage less than 0.5 V? Go to step 5.
Is the resistance 120±6 Ω?
Is there poor contact?
Is the resistance 120±6 Ω?
