Diagnosis and Testing Refer to Wiring Diagrams Section 307-01, for schematic and connector information. General Equipment  diagnostic equipment Inspection and Verification Verify the customer concern. Visually inspect for obvious signs of mechanical or electrical damage. Visual Inspection Mechanical Electrical Fluid level too high/low Poor condition of fluid Fluid leak Damaged shift mechanism/linkages Damaged automatic transmission/ transaxle casing Fuse(s) Relay(s) Wiring harness Electrical connector(s) Selector lever module Transmission control module (TCM) If an obvious cause for an observed or reported concern is found, correct the cause (if possible) before proceeding to the next step If the cause is not visually evident, verify the symptom and refer to the Ford diagnostic equipment to diagnose the system. Diagnostic Trouble Code (DTC) Chart NOTE: The following table should be used for guidance

Eclairage extérieur - Allumage automatique des phares Diagnostic et essais Se reporter au chapitre 417-01, du Manuel des schémas électriques pour les schémas et les informations sur les connecteurs. Outils spéciaux / Equipement d'atelier et outillage standard Kit de testeurs de bornes 29-011A Multimètre digital. Outil de diagnostic. Contrôle et vérification Note : Le module électronique générique (GEM) fait partie du boîtier électrique central (CJB). Note : Si le module GEM est remplacé, le module neuf doit être configuré après la pose. A cet effet, les données spécifiques au véhicule sont extraites du module à remplacer à l'aide de l'équipement de diagnostic et sont transférées dans le module neuf. Note : Avant d'extraire les données spécifiques au véhicule, s'assurer que toutes les connexions électriques du véhicule sont de nouveaux raccordées, de sorte que le module et l'outil de diagnostic puissent communiquer correct
