Eye Local 2 Can

WARNING: This page is about a different car, the 2024 Subaru Ascent. However, it is still accessible from the selected car via links, so may be relevant.

Trouble causes:

EYE local 2 CAN communication circuit is shorted to ground.
EYE local 2 CAN communication circuit is shorted to power supply.
EYE local 2 CAN communication circuit is shorted between lines.

CAUTION: Before performing diagnosis, refer to "CAUTION" in "General Description". Ref. to LAN SYSTEM (DIAGNOSTICS)>GENERAL DESCRIPTION>CAUTION .

NOTE:

When measuring the resistance of CAN communication circuit, measure it in sleep status. To enter sleep status
- With ignition switch OFF and key or switch operation stopped, keep the doors, trunk, and rear gate all closed for one minute or more.
- On model with the keyless access with push button start, keep the access key 2 m or more away from the vehicle.

CHECK BASIC DIAGNOSTIC PROCEDURE .
Check that the basic diagnosis has been performed up to STEP 3.

NOTE: Possible defective parts can be narrowed easily by inspection using Subaru Select Monitor before performing "CHECK CAN COMMUNICATION CIRCUIT" using a tester.

Was the basic diagnostic procedure performed?

Yes: Go to 2.

No: Perform the basic diagnostic procedure. Ref. to LAN SYSTEM (DIAGNOSTICS)>BASIC DIAGNOSTIC PROCEDURE>PROCEDURE .
CHECK FOR SHORT TO GROUND IN EYE LOCAL 2 CAN COMMUNICATION CIRCUIT .
1. Turn the ignition switch to OFF.
2. Disconnect the stereo camera connector.
3. Disconnect the wide angle mono camera connector.
4. Using a tester, measure the resistance between the wide angle mono camera connector and chassis ground.
  Connector & terminal
  
  (R579) No. 11 - Chassis ground:
  
  (R579) No. 12 - Chassis ground:
Is the resistance less than 10 Ω?

Yes: Repair or replace the short circuit to ground in harness between the wide angle mono camera connector and the stereo camera connector.

No: Go to 3.
CHECK FOR SHORT TO POWER SUPPLY IN EYE LOCAL 2 CAN COMMUNICATION CIRCUIT .
1. Turn the ignition switch to ON.
2. Using a tester, measure the voltage between the wide angle mono camera connector and chassis ground.
  Connector & terminal
  
  (R579) No. 11 (+) - Chassis ground (-):
  
  (R579) No. 12 (+) - Chassis ground (-):
Is the voltage 5 V or less?

Yes: Go to 4.

No: Repair or replace the short circuit to power supply in harness between the wide angle mono camera connector and the stereo camera connector.
CHECK FOR SHORT CIRCUIT BETWEEN LINES IN EYE LOCAL 2 CAN COMMUNICATION CIRCUIT .
1. Turn the ignition switch to OFF.
2. Using the tester, measure the resistance between terminals.
  Connector & terminal
  
  (R579) No. 11 - (R579) No. 12:
Is the resistance 1 MΩ or more?

Yes: Go to 5.

No: Repair or replace the short circuit between the lines of harness between the wide angle mono camera connector and the stereo camera connector.
CHECK END RESISTANCE .
1. Connect the stereo camera connector.
2. Using a tester, measure the resistance between terminals in the wide angle mono camera connector.
  Connector & terminal
  
  (R579) No. 11 - (R579) No. 12:
Is the resistance 114 - 126 Ω?

Yes: Go to 6.

No: Replace the stereo camera. Ref. to EYESIGHT>STEREO CAMERA .
CHECK END RESISTANCE .
1. Disconnect the stereo camera connector.
2. Connect the wide angle mono camera connector.
3. Using a tester, measure the resistance between terminals in stereo camera connector.
  Connector & terminal
  
  (R137) No. 4 - (R137) No. 16:
Is the resistance 114 - 126 Ω?

Yes: CAN communication circuit is normal.

No: Replace the wide angle mono camera. Ref. to EYESIGHT>WIDE ANGLE MONO CAMERA .
