DTC U2300:00

Global central configuration error

DETECTION CONDITION

• Any of following conditions occurs:

• No configuration of the instrument cluster.

• The configuration signal with the estimated CAN ID is not sent from the instrument cluster.

• The configuration signal value sent via CAN from the instrument cluster is unknown or invalid.

• The configuration signal value sent via CAN from the instrument cluster is a value other than the estimated value.

• The configuration signal value sent via CAN from the instrument cluster does not match the PCM value.

Diagnostic support note

• This is a continuous monitor (other).

• The check engine light does not illuminate.

• FREEZE FRAME DATA (Mode 2)/Snapshot data is not available.

• DTC is stored in the PCM memory.

FAIL-SAFE FUNCTION

• Operates by the previously learned configuration value.

POSSIBLE CAUSE

• CAN drive error (instrument cluster or PCM)

• Configuration data for the instrument cluster is incorrectly set

• CAN communication line malfunction between instrument cluster and PCM

• Instrument cluster terminal B—Front body control module (FBCM) terminal 2K

• Instrument cluster terminal D—Front body control module (FBCM) terminal 2I

• Front body control module (FBCM) terminal 2P—PCM terminal 2AK

• Front body control module (FBCM) terminal 2N—PCM terminal 2AL

• PCM connector or terminals malfunction

• Instrument cluster connector or terminals malfunction

• Instrument cluster loose

• Instrument cluster malfunction

• Error in non-volatile memory in PCM

• PCM malfunction

STEP

INSPECTION

ACTION

1

• Verify related Service Bulletins and/or on-line repair information availability.

• Is any related repair information available?

Yes

Perform repair or diagnosis according to the available repair information.

• If the vehicle is not repaired, go to the next step.

No

Go to the next step.

2

• Switch the ignition off, then ON (engine off).

• Perform the DTC Reading Procedure.

  (See ON-BOARD DIAGNOSTIC TEST [SKYACTIV-G 2.5].)

• Is the DTC U0155:00 also present?

Yes

Go to the applicable DTC inspection.

(See DTC U0073:00, U0101:00, U0104:00, U0121:00, U0131:00, U0140:00, U0151:00, U0155:00, U0214:00, U0235:00 [SKYACTIV-G 2.5].)

No

Go to the next step.

3

• Perform the instrument cluster DTC inspection using the M-MDS.

  (See DTC INSPECTION [INSTRUMENT CLUSTER].)

• Are any DTCs present?

Yes

Go to the applicable DTC inspection.

(See DTC TABLE [INSTRUMENT CLUSTER].)

No

Go to the next step.

4

• Switch the ignition off.

• Disconnect the PCM connector.

• Inspect for poor connection (such as damaged/pulled-out pins, corrosion).

• Is there any malfunction?

Yes

Repair or replace the connector and/or terminals, then go to Step 8.

No

Go to the next step.

5

• Disconnect the instrument cluster connector.

• Inspect for poor connection (such as damaged/pulled-out pins, corrosion).

• Is there any malfunction?

Yes

Repair or replace the connector and/or terminals, then go to Step 8.

No

Go to the next step.

6

• Inspect installation of instrument cluster.

• Is the instrument cluster installed securely?

Yes

Go to the next step.

No

Retighten the instrument cluster, then go to Step 8.

(See INSTRUMENT CLUSTER REMOVAL/INSTALLATION.)

7

• Inspect the instrument cluster.

  (See INSTRUMENT CLUSTER INSPECTION.)

• Is there any malfunction?

Yes

Replace the instrument cluster, then go to the next step.

(See INSTRUMENT CLUSTER REMOVAL/INSTALLATION.)

No

Go to the next step.

8

• Always reconnect all disconnected connectors.

• Clear the DTC from the PCM memory using the M-MDS.

  (See AFTER REPAIR PROCEDURE [SKYACTIV-G 2.5].)

• Switch the ignition ON (engine off) and wait for 15 s or more.

• Wait until the main relay is off (approx. 1 min).

• Perform the KOER self test.

  (See KOEO/KOER SELF TEST [SKYACTIV-G 2.5].)

• Is the same DTC present?

Yes

Repeat the inspection from Step 1.

• If the malfunction recurs, replace the PCM.

  (See PCM REMOVAL/INSTALLATION [SKYACTIV-G 2.5].)

Go to the next step.

No

Go to the next step.

9

• Perform the “AFTER REPAIR PROCEDURE”.

  (See AFTER REPAIR PROCEDURE [SKYACTIV-G 2.5].)

• Are any DTCs present?

Yes

Go to the applicable DTC inspection.

(See DTC TABLE [SKYACTIV-G 2.5].)

No

DTC troubleshooting completed.
