Pinpoint Tests

Pinpoint Test A: No Power in All Ignition Switch Positions — Vehicles with an Ignition Switch

Diagnostic Overview

Diagnostics in this manual assume a certain skill level and knowledge of Ford-specific diagnostic practices. Refer to Diagnostic Methods in Section 100-00 for information about these practices.

Refer to Wiring Diagrams Cell 13 , Power Distribution/BCM for schematic and connector information.

Normal Operation and Fault Conditions

The ignition switch receives fused battery voltage from BCM fuse 26 (5A). In the ACC or RUN position, this voltage is sent to the BCM . In the START position, this voltage is sent to both the BCM and the PCM. When the ignition switch is cycled to the OFF/LOCK position from any other position, the BCM begins a monitoring cycle. The monitoring cycle checks that the voltage supplied to the BCM from the ignition switch through the RUN/ACC, RUN/START and START circuits is delivered correctly for each ignition switch position.

DTC Fault Trigger Conditions
