STEP 4. Measure the voltage at combination meter
connector C-101 in order to power supply circuit to
combination meter (IG1 power supply).
(1) Disconnect combination meter connector C-101, and

measure at the wiring harness side.

(2) Turn the ignition switch to "ON" position.

(3) Measure the voltage between terminal 12 and ground.

• The voltage should measure approximately 12 volts

(battery positive voltage).

Q: Is the measured voltage approximately 12 volts (battery

positive voltage)?
YES : Go to Step 6.
NO : Go to Step 5.

STEP 5. Check the wiring harness between combination
meter connector C-101 (terminal 12) and the ignition
switch (IG1)

NOTE: Also check junction block connector C-211 and C-215
for loose, corroded, or damaged terminals, or terminals pushed
back in the connector. If inspecting junction block connector
C-211 or C-215 is damaged, repair or replace. Refer to
GROUP 00E, Harness Connector Inspection

P.00E-2

.

Q: Is the wiring harness between combination meter

connector C-101 (terminal 12) and the ignition switch
(IG1) in good condition?
YES : Retest the system.
NO : Repair the wiring harness. Check that the mode

switch and combination meter works normally.

STEP 6. Measure the resistance at combination meter
connector C-101 in order to the ground circuit to the
combination meter.
(1) Disconnect combination meter connector C-101, and

measure at the wiring harness side.

(2) Measure the resistance value between terminal 3, 5 and

ground.

• The resistance should be 2 ohms or less.

Q: Is the measured resistance 2 ohms or less?

YES : Go to Step 8.
NO : Go to Step 7.

STEP 7. Check the wiring harness between combination
meter connector C-101 (terminal 3 and 5) and ground.
Q: Is the wiring harness between combination meter

connector C-101 (terminal 3 and 5) and ground in good
condition?
YES : Procedure is complete. Retest the system.
NO : Repair the wiring harness. Check that the mode witch

and combination meter works normally.

STEP 8. Measure the resistance at MODE switch connector
C-32 to the ground circuit .
(1) Disconnect the mode switch connector C-32.

(2) Measure resistance between terminal 6 and ground.

• The measured value should be 2 ohm or less.

Q: Is the measured resistance 2 ohms or less?

YES : Go to Step 9.
NO : Repair the earth circuit and check mode switch

operation.

STEP 9. Check the wiring harness and terminals between
combination meter connector C-101 (terminal 16) and the
mode switch connector C-32 (terminal 1)

Q: Is the wiring harness between combination meter

connector C-101 (terminal 16) and the mode switch
connector C-32 (terminal 1) in good condition?
YES : Go to Step 10.
NO : Repair the wiring harness. Check that the mode

switch functions normally.

STEP 10. Measure the resistance between the combination
meter connector C-101 (terminal 16) and the mode switch
connector C-32 (terminal 1).
(1) Disconnect the combination meter connector C-101 and the

mode switch connector C-32.

(2) Measure resistance between combination meter C-101

(terminal 16) and mode switch connector C-32 (terminal 1).

• The measured value should be 2 ohm or less.

Q: Is the measured resistance 2 ohms or less?

YES : Go to Step 11.
NO : Repair the wiring circuit and check the mode switch

operation.
