STEP 4. Check the wiring harness between
combination meter connector C-113 (terminal 21)
and engine coolant temperature gauge unit
connector A-108 (terminal 1).
Check the input lines for open circuit and short cir-
cuit.
NOTE:
Prior to the wiring harness inspection, check interme-
diate connector C-53 <LHD> or C-35 <RHD>, and
repair if necessary.
Q: Is the wiring harness between combination meter
connector C-113 (terminal 21) and engine coolant
temperature gauge unit connector A-108 (terminal
1) in good condition?
YES :
Go to Step 6.
NO :
Repair or replace the damage
component(s).
STEP 5. Check the engine coolant temperature
gauge unit.
Refer to
Q: Is the engine coolant temperature gauge unit
normal?
YES :
Go to Step 6.
NO :
Replace the engine coolant temperature
gauge unit.
STEP 6. Retest the system
Q: Is the engine coolant temperature gauge normal?
YES :
The procedure is complete. (If no
malfunctions are found in all steps, an
intermittent malfunction is suspected. Refer
to GROUP 00 / How to Cope with
Intermittent Malfunction ).
NO :
Replace the combination meter.

Inspection Procedure 9: The high-beam indicator does not illuminate.
COMMENTS ON TROUBLE SYMPTOM
If the high-beam indicator does not illuminate, the
wiring harness connector(s) or the combination
meter may be defective.
PROBABLE CAUSES
• Malfunction of the combination meter
• Damaged harness wires and connectors
DIAGNOSIS PROCEDURE
STEP 1. Check of headlamps (high-beam)
Check that the headlamp (high beam) illuminates
normally.
Q: Is the check result normal?
YES :
Go to Step 2.
NO :
Repair the headlamp first.Refer to trouble

STEP 2. Connector check: C-113 combination
meter connector
Q: Is the check result normal?
YES :
Go to Step 3.
NO :
Repair the defective connector.
STEP 3. Resistance measurement at the C-113
combination meter connector.
(1) Disconnect the connector, and measure at the
wiring harness side.
(2) Check the resistance between the C-113
combination meter connector terminal No.13 and
body earth.
OK: Continuity exists (2
Ω or less)
Q: Is the check result normal?
YES :
Go to Step 5.
NO :
Go to Step 4.
STEP 4. Check the wiring harness from C-113
combination meter connector terminal No.13 to
body earth.
• Check the earth wires for open circuit.
Q: Is the check result normal?
YES :
The trouble can be an intermittent
malfunction (Refer to GROUP 00
− How to
use Troubleshooting/inspection Service
Points
− How to Cope with Intermittent
Malfunction ).
NO :
Repair the wiring harness.

STEP 5. Connector check: A-23X headlamp relay
(HI) connector
Q: Is the check result normal?
YES :
Go to Step 6.
NO :
Repair the defective connector.
STEP 6. Check the wiring harness from C-113
combination meter connector terminal No.24 to

No.3.
NOTE: Prior to the wiring harness inspection, check
intermediate connector C-54 <LHD> or C-14
<RHD>, and repair if necessary.
• Check the output lines for open circuit.
Q: Is the check result normal?
YES :
Go to Step 7.
NO :
Repair the wiring harness.
STEP 7. Retest the system.
Check that the headlamp indicator illuminates nor-
mally.
