Lancer L4-2.0L (4B11) (2008)
3. Measure the resistance between data link connector terminal 14 and body ground. <CAN_L>
OK: 1 kilo ohm or more
Q: Do all the resistances measure 1 kilo ohm or more?
YES : Go to Step 4.
NO : Repair the wiring harness between data link connector C-34 and ETACS-ECU connector C-301.
STEP 4. Check the wiring harness between data link connector C-34 and ETACS-ECU connector C-301 for a short to the power supply.
Measure the voltage at data link connector C-34.
1. Disconnect the scan tool and ETACS-ECU connector C-301, and measure the resistance at the wiring harness side of data link connector C-34.
2. Turn the ignition switch to the "ON" position.
3. Measure the voltage between data link connector terminal 6 and body ground. <CAN_H>
OK: 5 volts or less
4. Measure the voltage between data link connector terminal 14 and body ground. <CAN_L>
OK: 5 volts or less
Q: Do all the voltage measure 5 volts or less?
YES : Go to Step 5.
