2018 / ECLIPSE CROSS / EC - Workshop Manual
13 -FUEL > 13A-DIRECT INJECTION AND MULTIPOINT FUEL INJECTION (DI AND MPI) > TROUBLESHOOTING > SYMPTOM PROCEDURES > ALTHOUGH AS&G OFF SWITCH PRESSED, AS&G SYSTEM NOT SWITCHED
Inspection Procedure 18: Although AS&G OFF Switch Pressed, AS&G System Not Switched
OPERATION
- The battery voltage is supplied to the AS&G OFF switch from the IG1 relay.
- The ON/OFF signal is inputted to the engine-ECU connector terminal ASGM from the AS&G OFF switch.
FUNCTION
Pressing the AS&G OFF switch can optionally turn OFF the AS&G system or turn ON the AS&G system.
COMMENT ON TROUBLE SYMPTOM
The failure could possibly be caused by the failed AS&G OFF switch circuit and so on.
PROBABLE CAUSES
- Failed AS&G OFF switch
- Open/short circuit or harness damage in the AS&G OFF switch circuit or loose connector contact
- Failed engine-ECU
DIAGNOSIS PROCEDURE
STEP 1. M.U.T.-IIISE data list
STEP 2. Check the AS&G OFF switch itself.
STEP 3. Perform voltage measurement at AS&G OFF switch connector.
- Disconnect connector, and measure at harness side.
- Ignition switch: ON
- Voltage between terminal ETACS-ECU IG1 line and body earth.
OK: System voltage
Is the check result normal?
Go to Step 4.
Repair the connector(s), or check and repair of short to earth, and open circuit in IG1 line between ETACS-ECU connector and AS&G OFF switch connector.
STEP 4. Check of harness damage in IG1 line between ETACS-ECU connector and AS&G OFF switch connector.
Is the check result normal?
Go to Step 5. Repair the connector(s) or wiring harness.
STEP 5. Check of short to power supply, short to earth, open circuit, and harness damage in ASGM line between AS&G OFF switch connector and engine-ECU connector.
Is the check result normal?
Go to Step 6. Repair the connector(s) or wiring harness.
STEP 6. Check the trouble symptom.
