Inspection Procedure
1: Check the battery power supply circuit to the laser radar.
PROBABLE CAUSES
- Damaged harness or connector
- Malfunction of the laser radar
|
STEP 1. Resistance measurement at the laser radar connector
(E terminal).
|
|
(1)Disconnect the connector, and measure the resistance at the harness.
|
|
(2)Measure the resistance between the laser radar connector (E terminal) and body
earth. OK: Connect (2 Ω or lower)
|
|
Q.
Is the check result normal?
|
|
Go to Step 3.
|
|
|
|
Go to Step 2.
|
|
|
|
STEP 2. Disconnection check of the GND line between the laser radar
connector and body earth.
|
|
Q.
Is the check result normal?
|
|
The trouble can be an intermittent malfunction (Refer to GROUP 00 - How
to Use Troubleshooting/Inspection Service Points - How to Cope with Intermittent
Malfunction).
|
|
|
|
Repair the connector(s) or wiring harness.
|
|
|
|
STEP 3. Voltage measurement at the laser radar connector (IG terminal).
|
|
(1)Disconnect the connector, and measure the resistance at the harness.
|
|
(2)Turn the ignition switch to the "ON" position.
|
|
(3)Measure the voltage between the laser radar connector (IG terminal) and body earth. OK: Battery voltage

|
Q.
Is the check result normal?
|
|
Go to Step 5.
|
|
|
|
Go to Step 4.
|
|
|
|
STEP 4. Disconnection check of the IG line between the laser radar
connector and ignition switch.
|
|
Q.
Is the check result normal?
|
|
The trouble can be an intermittent malfunction (Refer to GROUP 00 - How
to Use Troubleshooting/Inspection Service Points - How to Cope with Intermittent
Malfunction).
|
|
|
|
Repair the connector(s) or wiring harness.
|
|
|
|
STEP 5. Check the trouble symptom.
|
|
Check that this system can communicate with the M.U.T.-III.
|
|
Q.
Is the check result normal?
|
|
The trouble can be an intermittent malfunction (Refer to GROUP 00 - How
to Use Troubleshooting/Inspection Service Points - How to Cope with Intermittent
Malfunction).
|
|
|
|
Replace the laser radar (Refer to ).
