13. CHECK GROUND CIRCUIT OF MOTOR.
1) Turn ignition switch OFF.
2) Disconnect motor connector.
3) Measure resistance between motor connector and
body.
Connector & terminal / Specified resistance:
(F13) No. 1—body / 1Ωor less
NOTE:
The check can also be made by analyzing the waves of the
motor sensor output signal with oscilloscope during the
TCS sequence control operation. If the ECM female con-
nector end gives correct value, skip steps 6 through 9
above.
If not, operate the TCS sequence control again and mea-
sure the value at motor sensor male connector end with the
motor sensor connector removed. If the value is OK, pro-
ceed with steps 8 and 9 above.

2) Disconnect connector from ABSCM.
3) Measure resistance between ABSCM and chassis
ground.
: Connector & terminal
(F49) No. 1—Chassis ground
(F49) No. 55—Chassis ground
Is resistance less than 0.5Ω?
: Go to step8G2.
: Repair ABSCM ground harness.
8G2CHECK POOR CONTACT IN CONNEC-
TORS BETWEEN BATTERY, IGNITION
SWITCH AND ABSCM.
: Is there poor contact in connectors between
battery, ignition switch and ABSCM?
: Repair connector.
: Go to step8G3.
8G3
CHECK SOURCES OF SIGNAL NOISE.
: Is the car telephone or the wireless trans-
mitter properly installed?
: Go to next.
: Properly install the car telephone or the wireless
transmitter.
: Are noise sources (such as an antenna)
installed near the sensor harness?
: Install the noise sources apart from the sensor
harness.
: Go to step8G4.
