(See DTC TABLE [PCM (SKYACTIV-G 2.5T)]
.) |
| No |
Go to the next step. |
| 2 |
INSPECT BATTERY
|
Yes |
Go to the next step. |
| No |
Recharge or replace the battery, then go to Step 6.
(See BATTERY RECHARGING
.)
(See BATTERY REMOVAL/INSTALLATION
.) |
| 3 |
INSPECT GENERATOR
|
Yes |
Go to the next step. |
| No |
Replace the generator, then go to Step 6.
(See GENERATOR REMOVAL/INSTALLATION [SKYACTIV-G 2.5T]

INSPECT AUDIO AMPLIFIER CONNECTOR CONDITION
- Switch the ignition off.
- Disconnect the negative battery terminal. (See NEGATIVE BATTERY TERMINAL DISCONNECTION/CONNECTION
.)
- Disconnect the audio amplifier connector.
- Inspect the connector engagement and connection condition and inspect the terminals for damage, deformation, corrosion, or disconnection.
- Is the connector normal?
|
Yes |
Go to the next step. |
| No |
Repair or replace the connector, then go to Step 6. |
| 5 |
VERIFY AUDIO AMPLIFIER POWER SUPPLY VOLTAGE
- Verify that the audio amplifier connector is disconnected.
- Connect the negative battery terminal. (See NEGATIVE BATTERY TERMINAL DISCONNECTION/CONNECTION
.)
- Switch the ignition ON (engine off or on).
- Measure the voltage at the audio amplifier terminal 3A (wiring harness side).
- Is the voltage B+?
|
Yes |
Go to the next step. |
| No |
Inspect the AUDIO1 25 A fuse and AUDIO 40 A fuse.
- Any fuse is blown:
- Refer to the wiring diagram and verify whether or not there is a common connector between MAIN 200 A fuse and audio amplifier terminal 3A.
If there is a common connector:
- Inspect the common connector and terminals for corrosion, damage, or disconnection and the common wiring harnesses for short to ground to determine the malfunctioning location.
- Repair or replace the malfunctioning location.
If there is no common connector:
- Repair or replace the wiring harness which is shorted to ground.
- Replace the fuse.
- Any fuse is damaged:
- All fuses are normal:
- Refer to the wiring diagram and verify whether or not there is a common connector between battery positive terminal and audio amplifier terminal 3A.
If there is a common connector:
- Inspect the common connector and terminals for corrosion, damage, or disconnection and the common wiring harnesses for an open circuit to determine the malfunctioning location.
Go to the next step. |

VERIFY THAT REPAIRS HAVE BEEN COMPLETED
|
Yes |
Repeat the inspection from Step 1.
- If the malfunction recurs, replace the audio amplifier.

VERIFY IF OTHER DTCs DISPLAYED
- Are any other DTCs displayed?
|
Yes |
Repair or replace the malfunctioning part according to the applicable DTC troubleshooting.
(See DTC TABLE [AUDIO AMPLIFIER] .) |
| No |
