STEP 14. Check the harness wires between vehicle speed
sensor connector B-35 and ignition switch (IG1).
NOTE: After checking junction block connectors C-73 and C-
74, intermediate connector C-17, check the wires. If junction
block connectors C-73 and C-74, intermediate connector C-17
are damaged, repair or replace them. Refer to GROUP 00E,
Harness Connector Inspection

P.00E-2

.

Q: Are the harness wires between vehicle speed sensor

connector B-35 and ignition switch (IG1) in good
condition?
YES : There is no action to be taken.
NO : Repair them. The speedometer should work normally.

STEP 15. Check the vehicle speed sensor ground circuit at
the vehicle speed sensor connector B-35.
(1) Disconnect the vehicle speed sensor connector B-35.
(2) Measure the resistance between terminal 2 and ground.

Q: Is the resistance less than 2 ohms?

YES : Go to Step 18.
NO : Go to Step 16.

STEP 16. Check the vehicle speed sensor connector B-35
for damage.
Q: Is vehicle speed connector B-35 in good condition?

YES : Go to Step 17.
NO : Repair or replace it. Refer to GROUP 00E, Harness

STEP 17. Check the harness wire between vehicle speed
sensor connector B-35 and ground.
Q: Is the harness wire between vehicle speed sensor

connector B-35 and ground in good condition?
YES : There is no action to be taken.
NO : Repair it. The speedometer should work normally.

STEP 18. Check the vehicle speed sensor signal circuit at
the vehicle speed sensor connector B-35.
(1) Disconnect the vehicle speed sensor connector B-35.
(2) Turn the ignition switch to "ON"
(3) Measure the voltage between terminal 3 and ground.

Q: Is the voltage approximately 9 volts or more?

More than approximately 9 volts : Replace the vehicle

speed sensor. The speedometer should work
normally.

Approximately 9 volts : Go to Step 19 .
