DTC U2300:00 [MZR 1.6]

id0102h3228300

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 1BE

―  Front body control module (FBCM) terminal 2N—PCM terminal 1AZ

•  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

Diagnostic Procedure

STEP	INSPECTION		ACTION
1	VERIFY RELATED SERVICE INFORMATION AVAILABILITY • Verify related Service Information availability. • Is any related Service Information available?	Yes	Perform repair or diagnosis according to the available Service Information. • If the vehicle is not repaired, go to the next step.
1		No	Go to the next step.
2	VERIFY DTC FOR MODULE COMMUNICATION • Switch the ignition off, then ON (engine off). • Perform the DTC Reading Procedure. (See ON-BOARD DIAGNOSTIC TEST [MZR 1.6].) • Is the DTC U0155:00 also present?	Yes	Go to the applicable DTC inspection. (See DTC U0073:00, U0121:00, U0131:00, U0151:00, U0155:00, U0214:00 [MZR 1.6].)
2		No	Go to the next step.
3	VERIFY INSTRUMENT CLUSTER DTC • 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].)
3		No	Go to the next step.
4	INSPECT PCM CONNECTOR CONDITION • 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.
4		No	Go to the next step.
5	INSPECT INSTRUMENT CLUSTER CONNECTOR CONDITION • 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.
5		No	Go to the next step.
6	INSPECT INSTALLATION OF INSTRUMENT CLUSTER • Inspect installation of instrument cluster. • Is the instrument cluster installed securely?	Yes	Go to the next step.
6		No	Retighten the instrument cluster, then go to Step 8. (See INSTRUMENT CLUSTER REMOVAL/INSTALLATION.)
7	INSPECT INSTRUMENT CLUSTER • 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.)
7		No	Go to the next step.
8	VERIFY DTC TROUBLESHOOTING COMPLETED • Always reconnect all disconnected connectors. • Clear the DTC from the PCM memory using the M-MDS. (See AFTER REPAIR PROCEDURE [MZR 1.6].) • Switch the ignition ON (engine off) and wait for 15 s or more. • Switch the ignition off. • Wait until the main relay is off (approx. 1 min). • Perform the KOER self test. (See KOEO/KOER SELF TEST [MZR 1.6].) • Is the same DTC present?	Yes	Repeat the inspection from Step 1. • If the malfunction recurs, replace the PCM. (See PCM REMOVAL/INSTALLATION [MZR 1.6].) Go to the next step.
8		No	Go to the next step.
9	VERIFY AFTER REPAIR PROCEDURE • Perform the “AFTER REPAIR PROCEDURE”. (See AFTER REPAIR PROCEDURE [MZR 1.6].) • Are any DTCs present?	Yes	Go to the applicable DTC inspection. (See DTC TABLE [MZR 1.6].)
9		No	DTC troubleshooting completed.
