STEP 1. Check the installation condition.
STEP 2. hood latch switch check.
STEP 3. Resistance measurement at hood latch switch connector (ground terminal).
(1) Disconnect the connector, and measure at the wiring harness side.
(2) Measure the resistance between the hood latch switch connector (ground terminal) and ground.OK: The resistance should be 2 ohms or less
Is the check result normal?
Go to Step 5. Go to Step 4.
STEP 4. Check of open circuit in ground line between hood latch switch connector and ground.
STEP 5. Check of open circuit in HOOD line between hood latch switch connector and ground.
STEP 6. Using scan tool (M.U.T.-III), check data list.
(1) caution | To prevent damage to scan tool (M.U.T.-III), always turn the ignition switch to the "LOCK" (OFF) position before connecting or disconnecting scan tool (M.U.T.-III). |
Connect scan tool (M.U.T.-III). Refer to "How to connect Scan Tool (M.U.T.-III)
."
(2) Check the input signals from the hood latch switch. | Item No. | Item name | Normal condition | 266 | Hood switch | ON |
|
Item No. | Item name | Normal condition |
266 | Hood switch | ON |
OK: Normal condition is displayed.
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 ETACS-ECU.
