TuningBot DTC Database · v4.37.15
12 manufacturer-specific interpretations across 12 manufacturers in the TuningBot DTC database.
FordThe control module registered the fault condition described as "PCM Keep Alive Memory Test Error Conditions". This is the manufacturer-specific definition used by Ford.
HondaThe control module detected a fault associated with the CAN data bus circuit or function; the stored code identifies the affected component rather than a single failure mode. This is the manufacturer-specific definition used by Honda.
JaguarThe control module detected improper operation of the Keep Alive Memory Test circuit. This is the manufacturer-specific definition used by Jaguar.
Land RoverThe control module detected a fault associated with the Power interuption in KAM circuit or function; the stored code identifies the affected component rather than a single failure mode. This is the manufacturer-specific definition used by Land Rover.
LexusThe control module detected improper operation of the Knock control. This is the manufacturer-specific definition used by Lexus.
ECM
MazdaThe control module registered the fault condition described as "Engine control module (ECM) - keep alive test error". This is the manufacturer-specific definition used by Mazda.
ECM
Mercedes-BenzThe control module detected a fault associated with the Acceleration sensor,” ESP/ASR system - rough road signal, comparison of wheel speeds circuit or function; the stored code identifies the affected component rather than a single failure mode. This is the manufacturer-specific definition used by Mercedes-Benz.
Trouble code(s) stored in other system(s)
OpelThe control module detected a fault associated with the Engine control module (ECM) - coding circuit or function; the stored code identifies the affected component rather than a single failure mode. This is the manufacturer-specific definition used by Opel.
PSAThe stored code identifies a fault of the Engine torque required by the driver information not received by the CAN fault (Engine ECU). Documented for the AM6/AT6 automatic gearbox ECU on Peugeot applications; the same PSA control units are also fitted to Citroën models. PSA documentation does not characterise the failure mode further.
ToyotaThe control module detected improper operation of the Knock control. This is the manufacturer-specific definition used by Toyota.
ECM
VAGThe control module detected an electrical fault in the Rough Road Acceleration circuit. This is the manufacturer-specific definition used by Volkswagen.
VolvoThe control module detected a fault associated with the CAN data bus, ETS - CAN data bus OFF circuit or function; the stored code identifies the affected component rather than a single failure mode. This is the manufacturer-specific definition used by Volvo.

Diagnostic Trouble Code (12 interpretations). The control module registered the fault condition described as "PCM Keep Alive Memory Test Error Conditions". This is the manufacturer-specific definition used by Ford.
P1605 is a manufacturer-specific code. In this database it is documented for: Ford, Honda, Jaguar, Land Rover, Lexus, Mazda, Mercedes-Benz, Opel, PSA, Toyota, VAG, Volvo. 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.
