Go to Step 4. Go to Step 3.
STEP 3. Check of open circuit in ground line between key reminder switch connector and the ground
STEP 4. Check of short to power supply, short to ground, and open circuit in HL1+ line between ETACS-ECU connector and key reminder switch connector
STEP 5. 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 key reminder switch.- Ignition switch: "LOCK" (OFF) (key inserted)
