TuningBot DTC Database · v4.37.15
1 manufacturer-specific interpretation across 1 manufacturer in the TuningBot DTC database.
PSAPSAThe control module detected that the Longitudinal acceleration sensor signal fault was not coherent with related operating data. Documented for the Bosch ESP 8.1 stability control ECU on Peugeot applications; the same PSA control units are also fitted to Citroën models.
Chassis: brakes, steering and suspension.
Manufacturer-defined range: the meaning can differ between brands.
Specific fault index within the subsystem.
Longitudinal acceleration sensor signal fault : Coherence. The control module detected that the Longitudinal acceleration sensor signal fault was not coherent with related operating data. Documented for the Bosch ESP 8.1 stability control ECU on Peugeot applications; the same PSA control units are also fitted to Citroën models.
C1503 is a manufacturer-specific code. In this database it is documented for: PSA. The same number can mean something different on other brands.
Not guaranteed. Powertrain (P) codes can be reliably disabled in the ECU calibration, but body, chassis and network codes depend on the specific control unit and how the fault is implemented - some can be handled, some cannot. Ask for a quote and our engineers will check your file and tell you, free of charge, whether C1503 is removable in your case.
