2009 Honda City U0155 Fault: Instrument Cluster Lights Fail After Battery Disconnection
The instrument cluster lights are not functioning properly. After disconnecting the negative battery cable for 5 minutes, the lights return to normal operation. This intermittent behavior is accompanied by Diagnostic Trouble Code (DTC) U0155, which indicates a lost communication link between the vehicle's Body Control Module and the Instrument Panel Cluster (IPC). The issue appears to be related to electrical signal instability or a fault in the IPC module's internal circuitry. Possible causes include poor wiring connections, voltage fluctuations during power cycling, or a malfunctioning IPC control module. A reset after battery disconnection temporarily resolves the problem, suggesting that the system is sensitive to power cycles and may require deeper diagnostics to identify root cause.
The term 'meter lights' refers to the instrument cluster indicators such as speedometer, fuel gauge, and warning lights. DTC U0155 specifically indicates a lost communication between the Body Control Module (BCM) and the Instrument Panel Cluster (IPC). This could stem from wiring issues, signal interference, or a faulty IPC module that fails to maintain stable communication after power cycles.
