DTC U2300-00: Global Central Configuration Error: Notes
DTC U2300:00 DETECTION CONDITION AND POSSIBLE CAUSE
| 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 is not available.
- Snapshot data is 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 1B-Front body control module (FBCM) terminal 2K
- Instrument cluster terminal 1D-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
