NOTE: Also check intermediate connector C-29 and joint con-
nector (1) C-01 for loose, corroded, or damaged terminals, or 
terminals pushed back in the connector. If intermediate connec-
tor C-29 or joint connector (1) C-01 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 1) and the fuse No.22 in good 
condition?
YES : Retest the system.
NO :  Repair the wiring harness. Check that the 

combination meter is normally.

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 joint connector (2) C-03, junction block con-
nector C-211 and C-215 for loose, corroded, or damaged termi-
nals, or terminals pushed back in the connector. If inspecting 
joint connector (2) C-03 or junction block connector C-211 or 
C-215 is damaged, repair or replace. Refer to GROUP 00E,

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 

combination meter is 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 : Retest the system.
NO :  Repair the wiring harness. Check that the 

combination meter is normally.

STEP 8. Retest the system.
Q: Is the check result satisfactory?

YES : The procedure is complete. (If no malfunctions are 

found in all steps, an intermittent malfunction is 
suspected. Refer to GROUP 00, How to Use 
Troubleshooting/Inspection Service Points 

− How to 

Cope with Intermittent Malfunction 

P.00-14

).

NO :  Replace the combination meter.
