Diagnostics in this service information assume a certain skill level and knowledge of Ford-specific diagnostic practices. REFER to: Diagnostic Methods .
| DTC | Description | Action |
|---|---|---|
| B1142:27 | Ignition Status 1: Signal Rate of Change Above Threshold |
NOTE:
This code sets when the wired start signal was detected by the ACM, but the ignition mode message from the BCM does not correspond (RUN mode). DIAGNOSE all other symptoms and Diagnostic Trouble Codes (DTCs) first. If no other symptom or DTC is present, DISREGARD this DTC. |
