TuningBot DTC Database · v4.37.15
2 manufacturer-specific interpretations across 2 manufacturers in the TuningBot DTC database.
ChryslerThe control module detected a fault associated with the Cruise control master switch - low voltage circuit or function; the stored code identifies the affected component rather than a single failure mode. This is the manufacturer-specific definition used by Chrysler.
PSAThe stored code identifies a fault of the Cooling circuit by-pass electrovalve. Documented for the Siemens SID 803 injection ECU (DW10BTED4 2.0 HDi) on Peugeot applications; the same PSA control units are also fitted to Citroën models. PSA documentation does not characterise the failure mode further.
Powertrain: engine, transmission and driveline systems.
Manufacturer-defined range: the meaning can differ between brands.
Specific fault index within the subsystem.
Diagnostic Trouble Code (2 interpretations). The control module detected a fault associated with the Cruise control master switch - low voltage circuit or function; the stored code identifies the affected component rather than a single failure mode. This is the manufacturer-specific definition used by Chrysler.
P1597 is a manufacturer-specific code. In this database it is documented for: Chrysler, PSA. The same number can mean something different on other brands.
If the fault logic lives in the ECU calibration, yes: our DTC Removal file service disables the specific fault entry. Checksum correction is not included: it is a separate, optional service. Not sure whether your case qualifies? Request a free assessment and our engineers will check your ECU file.
