2006 Ford Focus C-Max 1.6 TDCi (90) Zetec – Workshop Service & Repair Manual

Transmission problems can be frustrating, but here's a step-by-step guide to troubleshoot and fix them:

• Step 1: Check the transmission fluid level. Low fluid can cause gear shifting issues.
• Step 2: Inspect the transmission filter. A clogged filter can restrict fluid flow, leading to poor performance.
• Step 3: Examine the transmission pan for metal shavings or debris, indicating internal damage.
• Step 4: Test the transmission solenoids. Faulty solenoids can prevent the transmission from shifting correctly.
• Step 5: If the issue persists, consider a professional diagnosis to determine if a transmission rebuild or replacement is necessary.

Our manual provides detailed procedures and diagrams to guide you through these steps, ensuring your transmission is functioning properly.

Turbo issues can lead to reduced engine power. Follow these steps to diagnose and fix turbo problems:

• Step 1: Check the turbo hoses for any signs of cracks or leaks. Replace any damaged hoses.
• Step 2: Inspect the turbocharger for excessive play in the turbine shaft, which could indicate wear.
• Step 3: Ensure the wastegate actuator is functioning correctly, as a stuck actuator can cause over-boost or under-boost conditions.
• Step 4: Examine the intercooler for blockages or leaks that could be affecting turbo performance.
• Step 5: Test the turbo pressure using a boost gauge to ensure it is within the manufacturer's specifications.

Our manual offers comprehensive instructions and troubleshooting tips to help you maintain optimal turbo performance.

A faulty alternator can lead to battery drain and electrical issues. Here's how to address the problem:

• Step 1: Test the alternator output with a multimeter to ensure it is charging the battery correctly.
• Step 2: Inspect the alternator belt for wear or tension issues that could be affecting its operation.
• Step 3: Check the connections and wiring to the alternator for any signs of corrosion or loose connections.
• Step 4: If the alternator is not producing the correct voltage, consider replacing it with a new or rebuilt unit.
• Step 5: After replacing the alternator, recheck the charging system to confirm it is functioning properly.

Our manual includes detailed guidance on testing and replacing alternators, ensuring your electrical system remains reliable.

Limp-home mode is a protective feature that limits engine performance to prevent further damage. To resolve this:

• Step 1: Use an OBD-II scanner to read the fault codes stored in the engine control module (ECM).
• Step 2: Identify the underlying issue, such as sensor faults, turbo problems, or fuel system issues.
• Step 3: Repair or replace the faulty component based on the diagnostic code.
• Step 4: Clear the fault codes using the scanner and test drive the vehicle to ensure the issue is resolved.
• Step 5: If limp-home mode persists, further diagnosis may be necessary to identify more complex issues.

Our manual provides in-depth diagnostics and repair information to help you effectively address limp-home mode issues.

Stone chips can damage the paintwork and lead to rust. Here's how to manage and prevent them:

• Step 1: Clean the affected area with soap and water to remove dirt and debris.
• Step 2: Use touch-up paint that matches your vehicle's color to fill in the chipped area.
• Step 3: Allow the paint to dry, then apply a clear coat to protect the repair.
• Step 4: Polish the area gently to blend the repair with the surrounding paintwork.
• Step 5: Consider applying a clear protective film to the bonnet to prevent future stone chips.

Our manual offers tips and techniques for maintaining your vehicle's exterior and preventing further damage.
