2014 Jeep Compass Complete Service Manual 12882 Pages

The document provides general engine overhaul procedures, diagnostics, and maintenance information for the 2014 Jeep Compass Limited. It includes guidelines for cleaning, inspection, component assembly, and specific repair instructions for various engine systems, transmission, fuel systems, and interior and exterior components.

Engine Overhaul Procedures

•    General procedures include cleaning, inspection, assembly, and machine shop practices.

•    Use Magnaflux, Magnaglo, dye-check, ultrasonic, and X-ray inspections for detecting material flaws.

•    Cylinder heads can be pressure tested for cracks using air or water methods.

•    Bead blasting and chemical cleaning methods are used for engine component cleaning.
Fuel System and Emissions

•    PCM adjusts injector pulse width and ignition timing based on sensor inputs.

•    Oxygen sensors monitor exhaust gas for air-fuel ratio adjustments and catalytic converter efficiency.

•    Catalytic converters convert HC, CO, and NOx emissions into harmless gases.
Transmission and Diagnostics

•    Transmission Control Module (TCM) diagnostics include checking CAN Bus and DTC codes.

•    Low transmission fluid levels can cause symptoms; ensure proper fluid levels.

•    Axle shaft seal installation requires special tools for proper alignment and sealing.
Interior and Trim Removal/Installation

•    Use trim sticks for removing/installing scuff plates, liftgate panels, and trim panels.

•    Handle seat back panels carefully, ensuring retaining clips and zippers are properly secured.

•    Engine overhaul procedures: Includes general cleaning, inspection, assembly, and machine shop practices. Refer to specific articles for complete details.

•    Engine identification: Locate engine serial numbers on the cylinder block or VIN for identification.

•    Inspection techniques: Magnaflux, dye-check, ultrasonic, and x-ray inspections are used to detect cracks or flaws in engine components.

•    Cleaning methods: Bead blasting, solvent tanks, hot/cold tanks, and steam cleaning are used for engine parts. Aluminum parts require special care to prevent damage.

•    Cylinder head procedures: Removal and installation require careful handling to avoid warping, especially for aluminum heads.

•    Transmission diagnostics: Issues like DTC U0401 are resolved by checking CAN communication, PCM, and TCM.

•    Fuel system operation: PCM adjusts injector pulse width and monitors O2 sensors for efficient air-fuel ratio and catalytic converter efficiency.

•    Manual transmission service: Details on axle shaft seal installation, fluid level checks, and synchronizer ring removal.

Summary of All Chapters:
Inspection and Service Recommendations

•    Inspections must be performed before servicing a vehicle, and results should be documented and explained to the customer.

•    Services or part replacements are categorized as “Required” (due to functional failure) or “Suggested” (close to the end of useful life or based on customer preferences).

•    Severe driving conditions (e.g., stop-and-go traffic, extreme temperatures, towing) require following Severe Service schedules.
Examples of Required and Suggested Repairs

•    Required: Severely corroded exhaust pipe with a hole causing exhaust leaks.

•    Suggested: Rusted or weak exhaust pipe without leaks, indicating potential future failure.

•    Brake rotors must be replaced if worn below discard specifications.
Diagnostics and Programming

•    Diagnostic tools like StarSCAN® and StarMOBILE® are used for ECU/PCM programming and troubleshooting.

•    Calibration programming must be precise, as controllers cannot be reprogrammed to a different calibration.

•    DTC codes must be cleared and verified after repairs.
Audio System Diagnostics

•    Audio speaker circuits are monitored for open or short conditions. Resistance checks and wiring inspections are part of the diagnostics.

•    Amplified speaker systems require specific diagnostic tests to identify shorts or open circuits.
Transmission and Differential

•    Automatic transmission diagnostics include disassembly, inspection, and reassembly of components like the differential, ring gear, and bearings.

•    Special tools are required for removing and installing bearings and seals.
Interior and Trim Removal/Installation

•    Procedures for removing and installing trim panels, speakers, and subwoofers involve using specialized tools like trim sticks.

•    Care must be taken to avoid damaging clips and fasteners during removal.
Sunroof Removal and Installation

•    Steps involve disconnecting the battery, removing the sunroof module, and reinstalling components like the glass panel and motor.
Power Seats Diagnostics

•    Power seat switches and motors are tested for continuity and overload protection. Faulty components must be replaced.
Restraint Systems

•    Airbag systems are diagnosed by monitoring DTCs and verifying wiring connections. Active codes must be resolved before addressing stored codes.
General Guidelines

•    All repairs and suggestions must align with the manufacturer’s recommendations and documented experience.

•    Technicians should ensure proper communication with customers and provide detailed explanations of required or suggested services.

This document provides comprehensive guidelines for vehicle inspections, diagnostics, and repairs, emphasizing safety, accuracy, and customer communication.
