Lancer L4-2.4L SOHC (2005)
STEP 2. Check the driver's door lock key cylinder switch.
Disconnect door lock key cylinder switch (LH) connector E-01. Then check continuity between the switch terminals.
Q: Is the driver's door lock key cylinder switch in good condition?
YES: Go to Step 3.
NO: Replace the driver's door lock key cylinder switch. If the systems, which are described in "CIRCUIT OPERATION", work normally, the input
signal from the driver's door lock key cylinder switch should be normal.
STEP 3. Check the ground circuit to the driver's door lock key cylinder switch. Measure the resistance at driver's door lock key cylinder switch
connector E-01.
1. Disconnect driver's door lock key cylinder switch connector E-01 and measure the resistance available at the wiring harness side of the connector.
2. Measure the resistance value between terminal 2 and ground.
-
The resistance should equal 2 ohms or less.
Q: Is the measured resistance 2 ohms or less?
