4.CHECK HARNESS (GROUND SHORT CIRCUIT). Using the tester, measure the resistance of harness between audio (7-inch display) connector or navigation unit connector and chassis ground. Connector & terminal Sedan model (i146) No. 1 — Chassis ground: (i146) No. 2 — Chassis ground: (i146) No. 3 — Chassis ground: (i146) No. 4 — Chassis ground: OUTBACK model (i146) No. 1 — Chassis ground: (i146) No. 2 — Chassis ground: (i146) No. 3 — Chassis ground: (i146) No. 4 — Chassis ground: | Is the resistance 1 M- or more- | Diagnostic Procedure with Diagnostic Trouble Code (DTC) > DTC B224A BACKUP CAMERA | Repair the short to ground in harness between audio (7-inch display) connector or navigation unit connector and rearview camera. |
5.CHECK HARNESS (SHORT CIRCUIT TO POWER SUPPLY). 1) Turn the ignition switch to ON. 2) Using the tester, measure the voltage between audio (7-inch display) connector or navigation unit connector and chassis ground. (With each connector disconnected) Connector & terminal Sedan model (i146) No. 1 (+) — Chassis ground (−): (i146) No. 2 (+) — Chassis ground (−): (i146) No. 3 (+) — Chassis ground (−): (i146) No. 4 (+) — Chassis ground (−): OUTBACK model (i146) No. 1 (+) — Chassis ground (−): (i146) No. 2 (+) — Chassis ground (−): (i146) No. 3 (+) — Chassis ground (−): | Is the voltage less than 1 V- | Diagnostic Procedure with Diagnostic Trouble Code (DTC) > DTC B224A BACKUP CAMERA | Repair the short to power supply in harness between audio (7-inch display) connector or navigation unit connector and rearview camera. |
6.CHECK HARNESS (OPEN CIRCUIT). 1) Disconnect the audio (7-inch display) connector or navigation unit connector. 2) Disconnect the inhibitor switch connector. 3) Using the tester, measure the resistance of harness between inhibitor switch connector or back-up light switch connector and audio (7-inch display) connector or navigation unit connector. Connector & terminal CVT model (i87) No. 2 — (T7) No. 7: MT model (i87) No. 2 — (B24) No. 1: | Is the resistance less than 1 -- | Diagnostic Procedure with Diagnostic Trouble Code (DTC) > DTC B224A BACKUP CAMERA | Repair the open circuit of harness between audio (7-inch display) connector or navigation unit connector and inhibitor switch connector or back-up light switch connector. |
7.CHECK HARNESS (GROUND SHORT CIRCUIT). Using the tester, measure the resistance of harness between audio (7-inch display) connector or navigation unit connector and chassis ground. Connector & terminal (i87) No. 2 — Chassis ground: | Is the resistance 1 M- or more- | Diagnostic Procedure with Diagnostic Trouble Code (DTC) > DTC B224A BACKUP CAMERA | Repair the short to ground in harness between audio (7-inch display) connector or navigation unit connector and inhibitor switch connector or back-up light switch connector. |
8.CHECK HARNESS (SHORT CIRCUIT TO POWER SUPPLY). 1) Turn the ignition switch to ON. 2) Using the tester, measure the voltage between audio (7-inch display) connector or navigation unit connector and chassis ground. (With each connector disconnected) Connector & terminal (i87) No. 2 (+) — Chassis ground (−): | Is the voltage less than 1 V- | Diagnostic Procedure with Diagnostic Trouble Code (DTC) > DTC B224A BACKUP CAMERA | Repair the short to power supply in harness between audio (7-inch display) connector or navigation unit connector and inhibitor switch connector or back-up light switch connector. |
9.CHECK REARVIEW CAMERA. Check the rearview camera according to the instructions of rearview camera operation manual. | | Replace the rearview camera. Rearview Camera System | Replace the audio (7-inch display) or navigation unit. Audio Navigation Body |
