1995 Ford Bronco Air Bag System Wiring Diagram - Diagnostic Monitor & Sensors

This document is a wiring schematic (reference R11258-A) for a Ford air bag (SRS) system, uploaded to a 1995 Ford Bronco gallery. It shows the Air Bag Diagnostic Monitor with its internal thermal fuse and back-up power supply (23-25 volts), a 'Hot at All Times' feed at pin 13, and connections to the Safing Sensor, Air Bag Diagnostic Module, driver air bag (1.0 Ω), the air bag sliding contact (clockspring, winding 0.25-0.5 Ω per leg), and the LH front and RH front radiator air bag sensors and brackets. Numbered circuits with wire colors are labeled throughout: 623 P/W, 611 W/O, 612 P/O, 613 DB/W, 614 GY/O, 615 GY/W, 57 BK (ground), 624 Y/W, 625 Y/LG, 617 PK/O, 619 PK/W, 620 R/LB, and 618 P/LG. Diagnostic monitor connector pins 1, 2, 3, 6, 8, 10, 11, 12, 13, 15, 16, 17, 18, 20, 21, and 23 are identified. A service note explains that a shorting bar exists in the gray diagnostic monitor harness connector and that the plastic wedge must be removed from the gray connector before checking circuit 624 or 617 for a short to ground. Useful for diagnosing air bag lamp codes and circuit continuity/resistance checks.
