Lancer Sportback L4-2.4L (4B12) (2010)
STEP 4. Check the power supply circuit to the accessory socket (front floor console) and accessory socket (rear floor console) [vehicles with
accessory socket (rear floor console)]. Measure the voltage at accessory socket (front floor console) connector C-28 and accessory socket (rear
floor console) connector C-24 [vehicles with accessory socket (rear floor console)].
1. Disconnect the connector, and measure at the wiring harness-side connector.
2. Turn the ignition switch to the "ACC" or "ON" position.
3. Measure the voltage between accessory socket (front floor console) connector C-28 terminal No.2 and ground.
-
The voltage should measure approximately 12 volts (battery positive voltage).
4. Measure the voltage between accessory socket (rear floor console) connector C-24 terminal No.2 and ground.
-
The voltage should measure approximately 12 volts (battery positive voltage).
Q: Is the measured voltage approximately 12 volts (battery positive voltage)?
YES : Go to Step 7.
NO [accessory socket (front floor console) side] : Go to Step 5.
NO [accessory socket (rear floor console) side] : Go to STEP 6.
STEP 5. Check the wiring harness between accessory socket (front floor console) connector C-28 terminal No.2 and ETACS-ECU connector
C-315 terminal No.3.
-
Check the power supply lines (battery power supply) for open circuit and short circuit.
Q: Is the wiring harness between accessory socket (front floor console) connector C-28 terminal No.2 and ETACS-ECU connector C-315 terminal
No.3 in good condition?
YES : Go to Step 7.
NO : Repair the wiring harness.
STEP 6. Check the wiring harness between accessory socket (rear floor console) connector C-24 terminal No.2 and ETACS-ECU connector
C-315 terminal No.12.
-
Check the power supply lines (battery power supply) for open circuit and short circuit.
NOTE: Check C-26 intermediate connector, and repair if necessary.
Q: Is the wiring harness between accessory socket (rear floor console) connector C-24 terminal No.2 and ETACS-ECU connector C-315 terminal
No.12 in good condition?
YES : Go to Step 7.
NO : Repair the wiring harness.
STEP 7. Check the ground circuit to the accessory socket (front floor console) and accessory socket (rear floor console) connector [vehicles with
accessory socket (rear floor console)]. Measure the resistance at accessory socket (front floor console) connector C-28 and accessory socket
(rear floor console) connector C-24 [vehicles with accessory socket (rear floor console)].
1. Disconnect the connector, and measure the resistance available at the wiring harness side of the connector.
2. Measure the resistance value between accessory socket (front floor console) connector C-28 terminal No.1 and ground.
-
The resistance should be 2 ohms or less.
3. Measure the resistance value between accessory socket (rear floor console) connector C-24 terminal No.1 and ground. [vehicles with accessory
socket (front floor console)]
-
The resistance should be 2 ohms or less.
Q: Is the measured resistance 2 ohms or less?
YES : Go to Step 10.
NO [accessory socket (front floor console) side] : Go to Step 8.
NO [accessory socket (rear floor console) side] : Go to STEP 9.
