Circuit/System Verification

1. Verify DTC B356A is not set.

• If DTC is set, refer to DTC B356A B356A.

2. Verify DTC B0987 is not set.

• If DTC is set, refer to Circuit/System Testing.

Circuit/System Testing

1. Ignition OFF, disconnect the harness connector at the K109 Front View Camera Module and the harness connector at the S48D Multifunction Switch 2 - Instrument Panel.

2. Ignition ON, test for greater than 11 V between the ignition circuit terminal 3 at the S48D Multifunction Switch 2 - Instrument Panel harness connector and ground.

• If less than the specified value, test the ignition circuit for a short to ground or an open/high resistance.

3. Test for less than 0.3 V between the control circuit terminal 8 at the S48D Multifunction Switch 2 - Instrument Panel harness connector and ground.

• If greater than the specified value, test the control circuit for a short to voltage.

4. Ignition OFF, test for infinite resistance between the control circuit terminal 8 at the S48D Multifunction Switch 2 - Instrument Panel harness connector and ground.

• If less than the specified value, test control circuit for a short to ground.

5. Test for less than 5 ohms between the S48D Multifunction Switch 2 - Instrument Panel control circuit terminal 8 and the control circuit terminal 4 at the K109 Front View Camera Module harness connector

• If greater than the specified value, test the control circuit for an open/high resistance.

6. If all circuits test normal, connect the harness connector to the K109 Front View Camera Module, replace the S48D Multifunction Switch 2 - Instrument Panel and verify the DTC does not reset.

• If the DTC resets, replace the K109 Front View Camera Module.
