8B1CHECK INPUT SIGNAL FOR STARTER
MOTOR.
1) Turn ignition switch to OFF.
2) Disconnect connector from starter motor.
3) Turn ignition switch to ST.
OBD0100A
4) Measure power supply voltage between starter motor
connector terminal and engine ground.
: Connector & terminal
(B14) No. 1 (+)—Engine ground ( ):
Is the voltage more than 10 V?
NOTE:
On AT vehicles, place the selector lever in the“P”or“N”
position.
On MT vehicles, depress the clutch pedal.
: Go to step8B2.
: Go to step8B3.

3) Measure resistance of ground cable between ground
cable terminal and engine ground.
: Is resistance less than 5Ω?
: Check starter motor.
: Repair open circuit of ground cable.
8B3CHECK HARNESS BETWEEN BATTERY
AND IGNITION SWITCH CONNECTOR.
1) Turn ignition switch to OFF.
2) Remove SBF No. 4 from main fuse box.
3) Measure resistance of fuse.
: Is resistance less than 1Ω?
: Replace SBF No. 4.
: Go to next step 4).

6) Measure power supply voltage between ignition switch
connector and chassis ground.
: Connector & terminal
(B72) No. 1 (+)—Chassis ground ( ):
Is the voltage more than 10 V?
: Go to step8B4.
: Repair harness between ignition switch and SBF
No. 4 connector.

8B4CHECK INHIBITOR SWITCH. (AT
VEHICLES ONLY)
1) Turn ignition switch to OFF.
2) Disconnect connector from transmission.
3) Measure resistance between transmission harness
connector receptacle’s terminals.
: Connector & terminal
(T3) No. 11—No. 12:
Is the resistance less than 10Ω?
: Repair harness between starter motor and ignition
switch connector.
: Repair or replace inhibitor switch.
