Inspection & Verification
WARNING: This page is about a different car, the 2002 Ford Focus. However, it is still accessible from the selected car via links, so may be relevant.
- Verify customer's original problem by operating system in question. Inspect vehicle for any obvious electrical component wiring or connector damage. Inspect connectors for loose, damaged or corroded terminals. Check related fuses for system in question.
- Inspect Data Link Connector (DLC) pins for damage. See Fig 1. DLC is located below left side of dash, near steering column. If pins are okay, go to next step. If pins are damaged, repair as necessary and retest system.
- If problem is still present after performing inspection, connect scan tool to DLC. Select vehicle to be tested from scan tool menu. If scan tool does not communicate with vehicle, ensure program card is properly installed. Check scan tool cable connections and ensure ignition is on. If scan tool still does not communicate with vehicle, perform TEST I: NO MODULE/NETWORK COMMUNICATION - ALL MODULES under SYMPTOM TESTS. If scan tool communicates with vehicle, perform data link diagnostic test. See DATA LINK DIAGNOSTIC TEST .
