Diagnosis / Trigger Conditions

The root cause of the Jeep Compass P2601-00 fault is identified as an auxiliary coolant pump blockage. Technicians will use a diagnostic scan tool, such as wiTECH, to confirm the presence of the DTC and perform preliminary diagnostics. These checks include verifying the coolant level and type, inspecting for leaks or damage in the high-temperature coolant circuit piping, and checking the power supply fuse for the auxiliary water pump supplementary heater pump.

Further diagnostic steps involve inspecting the wire harness connectors for damage, corrosion, or deformation, and checking for open or short circuits in the wiring of the auxiliary water pump supplementary heater pump supply line and the LIN line between the pump and the Hybrid Control Processor (HCP).

Repair Procedure Summary

The repair outlined in TSB 07-001-25 involves a straightforward replacement of the affected components. After confirming the Jeep Compass P2601-00 DTC and ruling out other potential electrical issues, the primary steps are:

1. Verify DTCs: Use a wiTECH scan tool to confirm that DTC P2601-00 is present in the Hybrid Control Processor (HCP).
2. Preliminary Diagnostics: Perform detailed checks of the coolant system, wiring, and fuses as described in the diagnosis section.
3. Component Replacement: If diagnostics confirm the auxiliary coolant pump blockage, the auxiliary coolant pump and the pump inlet pipe are replaced. Detailed service procedures for these replacements are available in DealerCONNECT/Service Library under
