POSSIBLE CAUSES
• Damaged harness wires and connectors
• Malfunction of combination meter
DIAGNOSTIC PROCEDURE
Step 1. Connector check: Combination meter
connector C-02.
Q: Is combination meter connector C-02 in good
condition?
YES :
Go to Step 2.
NO :
Repair the defective connector.
Step 2. Voltage measurement at combination
meter connector C-02 in order to power supply
circuit to combination meter (battery power
supply).
(1) Disconnect combination meter connector C-02,
and measure at the wiring harness side.
(2) Turn the ignition switch to "LOCK" (OFF) position.
(3) Measure the voltage between terminal 40 and
earth.
OK: Battery voltage
Q: Is the check result normal?
YES :
Go to Step 4.
NO :
Go to Step 3.

Step 3. Check the wiring harness between
combination meter connector C-02 (terminal 40)
and battery (fusible link No.26).
NOTE: Also check joint connector C-32 <LH drive
vehicles> or C-31 <RH drive vehicles> and
intermediate connector C-128 for loose, corroded, or
damaged terminals, or terminals pushed back in the
connector. If joint connector C-32 <LH drive
vehicles> or C-31 <RH drive vehicles> or
intermediate connector C-128 is damaged, repair or
replace the connector.
Q: Is the wiring harness between combination meter
connector C-02 (terminal 40) and battery (fusible
link No.26) in good condition?
YES :
Retest the system.
NO :
Repair the wiring harness.
Step 4. Voltage measurement at combination
meter connector C-02 in order to power supply
circuit to combination meter (ACC power
supply).
(1) Disconnect combination meter connector C-02,
and measure at the wiring harness side.
(2) Turn the ignition switch to "ACC" position.
(3) Measure the voltage between terminal 20 and
earth.
OK: Battery voltage
Q: Is the check result normal?
YES :
Go to Step 6.
NO :
Go to Step 5.

Step 5. Check the wiring harness between
combination meter connector C-02 (terminal 20)
and ignition switch (ACC).
NOTE:
Also check joint connector C-01, junction block
connector C-202 and C-205 for loose, corroded, or
damaged terminals, or terminals pushed back in the
