Determination Procedure
CAUTION:
- When disconnecting the connector, verify that there is no looseness, damage, deformation, corrosion, or poor connection of the connector terminals.
- When inspecting the DLC-2, touch it with a paper clip or similar thin pin without directly inserting a tester into the terminals.
- Disconnect the negative battery cable before performing any work that requires handling of connectors.
| Step | Inspection | Action | |

| No | Go to the next step. | ||
| 3 | INSPECT AUDIO UNIT FOR SHORT TO POWER SUPPLY
|
Yes | Replace the audio unit because there is a short to power supply in the audio unit. (See AUDIO UNIT REMOVAL/INSTALLATION .) |
| No | Go to the next step. | ||
| 4 | INSPECT SIRIUS SATELLITE RADIO UNIT FOR SHORT TO POWER SUPPLY
|
Yes | Replace the SIRIUS satellite radio unit because there is a short to power supply in the SIRIUS satellite radio unit. (See SIRIUS SATELLITE RADIO UNIT REMOVAL/INSTALLATION .) |
| No | Go to the next step. | ||
| 5 | INSPECT Bluetooth UNIT FOR SHORT TO POWER SUPPLY
|
Yes | Replace the Bluetooth unit because there is a short to power supply in the Bluetooth unit. (See BLUETOOTH UNIT REMOVAL/INSTALLATION .) |
| No | Go to the next step. | ||
| 6 | INSPECT INFORMATION DISPLAY FOR SHORT TO POWER SUPPLY
