STEP 5. Check the wiring harness between C-169
multivision display connector terminal No.25 and
earth.

• Check the earth wires for open circuit.

NOTE:

Prior to the wiring harness inspection, joint connector
C-120, and repair if necessary.

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 6. Resistance measurement at C-167
multivision display connector.

(1) Disconnect C-167 multivision display connector,

and measure the resistance available at the
wiring harness side of the connector.

(2) Measure the resistance between C-167

multivision display connector terminal 55 and
earth.

OK: Continuity exists (2

Ω or less)

Q: Is the check result normal?

YES :

Go to Step 8.

NO :

Go to Step 7.

STEP 7. Check the wiring harness between C-167
multivision display connector terminal No.55 and
earth.

• Check the earth wires for open circuit.

NOTE:

Prior to the wiring harness inspection, joint connector
C-120, and repair if necessary.

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 8. Voltage measurement at C-170
multivision display connector.

(1) Disconnect C-170 multivision display connector,

and measure at the wiring harness-side
connector.

(2) Voltage between C-170 multivision display

terminal No.14 and the body earth

OK: System voltage

Q: Is the check result normal?

YES :

Go to Step 10.

NO :

Go to Step 9.

STEP 9. Check the wiring harness between C-170
multivision display connector terminal No.14 and
ignition switch (ACC).

• Check the power supply lines (battery supply) for

open circuit and short circuit.

NOTE:

Prior to the wiring harness inspection, check junction
block connectors C-207, C-208 and joint connector
C-127, and repair if necessary.

Q: Is the check result normal?

YES :

Go to Step 10.

NO :

Repair the wiring harness.
