A/C compressor request - compressor relay, open circuit
Land Rover · climate_control
Data confidence62%
The control module detected an interruption (open circuit) in the A/C compressor request - compressor relay circuit, so the expected electrical continuity was not present. This is the manufacturer-specific definition used by Land Rover.
Brake switch signal : Lack of coherence between the 2 brake pedal signals
PSA · braking
Data confidence72%
The control module detected the fault condition "Lack of coherence between the 2 brake pedal signals" for the Brake switch signal. Documented for the Bosch EDC16C34 injection ECU (DV6TED4 1.6 HDi) on Peugeot applications; the same PSA control units are also fitted to Citroën models.

Frequently asked questions about P1536
What does P1536 mean?
Diagnostic Trouble Code (10 interpretations). The control module detected that the A/C System ECT temperature exceeded its permissible limit. This is the manufacturer-specific definition used by Chrysler.
Is P1536 generic or manufacturer-specific?
P1536 is a manufacturer-specific code. In this database it is documented for: Chrysler, Ford, Land Rover, PSA, VAG. The same number can mean something different on other brands.
Can TuningBot remove P1536 at file level?
If the fault logic lives in the ECU calibration, yes: our DTC Removal file service disables the specific fault entry and, where the ECU needs it, corrects the checksum too. Not sure whether your case qualifies? Request a free assessment and our engineers will check your ECU file.
