°
?

CHECK OPEN CIRCUIT IN G SENSOR OUT-
PUT HARNESS AND GROUND HARNESS.
1) Turn the ignition switch to OFF.
2) Disconnect the connector from ABSCM&H/
U.
3) Measure the resistance between
ABSCM&H/U connector terminals.
Connector & terminal
(B301) No. 21 — No. 10:
Is the resistance 1.8 — 2.4
k
Ω
?
Go to step 9.
Repair the har-
ness connector
between G sensor
and ABSCM&H/U.
9
CHECK GROUND SHORT OF HARNESS.
Measure the resistance between ABSCM&H/U
connector and chassis ground.
Connector & terminal
(B301) No. 21 — Chassis ground:
Is the resistance more than 1
M
Ω
?
Go to step 10.
Repair the har-
ness connector
