| Step | Check | Yes | No |
|---|---|---|---|
| 1 CHECK IGNITION SWITCH. | Is the ignition switch ON? | Go to step 2 . | Turn the ignition switch to ON, and select {ADA adaptive cruise control system} using the Subaru Select Monitor. |
| 2 CHECK BATTERY. Turn the ignition switch to OFF. Measure the battery voltage. | Is the voltage 10 V or more? | Go to step 3 . | Charge or replace the battery. |
| 3 CHECK BATTERY TERMINAL. | Is the battery terminal contact proper? | Go to step 4 . | Connect the battery terminal securely or replace it. |
| 4 CHECK SUBARU SELECT MONITOR COMMUNICATION. Turn the ignition switch to ON. Using the Subaru Select Monitor, check whether the communication can be executed normally. | Is the communication between Subaru Select Monitor and other unit normal? | Go to step 5 . | Check the connection of Subaru Select Monitor. |
| 5 CHECK LAN SYSTEM. Inspect LAN system. | Is there any fault? | Repair according to diagnosis for LAN system. | Go to step 6 . |
| 6 CHECK HARNESS CONNECTOR BETWEEN STEREO CAMERA AND DATA LINK CONNECTOR. Turn the ignition switch to OFF. Disconnect the stereo camera connector. Measure the resistance between the stereo camera and the data link connector. Connector & terminal (R137) No. 10 - (B40) No. 6: (R137) No. 9 - (B40) No. 14 | Is the resistance less than 10 ohms? | Go to step 7 . | Repair or replace the harness and connectors between the stereo camera and data link connector. |
| 7 CHECK POWER SUPPLY CIRCUIT. Turn the ignition switch to ON. Connector & terminal (R137) No. 6 (+) - Chassis ground (-) | Is the voltage 10 V or more? | Go to step 8 . | Check the harness from battery to stereo camera. |
| 8 CHECK GROUND CIRCUIT. Turn the ignition switch to OFF, then disconnect the ground cable from battery. Measure the resistance between harness connector of stereo camera and chassis ground. Connector & terminal (R137) No. 7 - Chassis ground: (R137) No. 15 - Chassis ground | Is the resistance less than 10 ohms? | Go to step 9 . | Check the harness from stereo camera to chassis ground. |
| 9 CHECK CONNECTOR. | Is there poor contact of stereo camera connector? | Repair the connector, or replace harness. | Replace the stereo camera. < Refer to REMOVAL , Stereo Camera. > |

| Step | Check | Yes | No |
|---|---|---|---|
| 1 CHECK CRUISE CONTROL COMMAND SWITCH CIRCUIT. Remove the driver's airbag module. < Refer to REMOVAL , Driver's Airbag Module. > Disconnect the harness connector of cruise control command switch. Turn the ignition switch to ON. Measure the voltage between harness connector terminal and chassis ground. Connector & terminal (ST3) No. 4 (+) - Chassis ground (-): (ST3) No. 3 (+) - Chassis ground (-) | Is the voltage 5 V or more? | Go to step 2 . | Check the harness between cruise control command switch and ECM, and the steering roll connector for open or short circuit, or for poor contact. |
| 2 CHECK CRUISE CONTROL COMMAND SWITCH CIRCUIT. Turn the ignition switch to OFF. Remove the cruise control command switch. < Refer to REMOVAL , Cruise Control Command Switch. > Measure the resistance between harness connector terminal and chassis ground. Connector & terminal (ST3) No. 2 - Chassis ground | Is the resistance less than 10 ohms? | Go to step 3 . | Check for open circuit between cruise control command switch and chassis ground. |
| 3 CHECK CRUISE CONTROL COMMAND SWITCH. Check the cruise control command switch. | Is the cruise control command switch normal? | Replace the ECM. < Refer to REMOVAL , Engine Control Module (ECM). > < Refer to REMOVAL , Engine Control Module (ECM). > | Replace the cruise control command switch. |

Scheme 10
| Step | Check | Yes | No |
|---|---|---|---|
| 1 CHECK SWITCH. Turn the ignition switch to OFF. Disconnect the stereo camera connector. Using the tester, measure the resistance between terminals. Connector & terminal (R137) No. 12 - Chassis ground: (R137) No. 13 - Chassis ground | Is the resistance 10 ohms or less? | Go to step 2 . | If the code is still detected after restoring, replace the stereo camera. < Refer to REMOVAL , Stereo Camera. > |
| 2 CHECK HARNESS. Disconnect the switch connector for the stereo camera cover. Using the tester, measure the resistance between terminals. Connector & terminal (R137) No. 12 - Chassis ground: (R137) No. 13 - Chassis ground | Is the resistance 10 ohms or less? | Repair or replace the harness. | Go to step 3 . |
| 3 CHECK SWITCH. Using the tester, measure the resistance of the switch. Connector & terminal (R405) No. 11 - No. 12: (R405) No. 10 - No. 12 | Does the resistance change when the switch is operated? | Repair or replace the harness. | Replace the switch. |
