WARNING: This page is about a different car, the 2011 Ford Pickup, 2011 Ford F550 Super Duty, 2011 Ford F450 Super Duty, and 2011 Ford Cab & Chassis. However, it is still accessible from the selected car via links, so may be relevant.
The Circuit Deactivation Ignition Module (CDIM) receives run circuit information from the ignition switch and provides a run/acc output to the Body Control Module (BCM). The CDIM has microprocessors that continually monitor these inputs and outputs. The applicable DTC sets if a circuit failure is detected.
- DTC B1355 (Ignition Run Circuit Failure) - sets if the CDIM determines that the input circuit from the ignition switch is open or shorted to ground during normal operation.
- DTC B1359 (Ignition Run/Acc Circuit Failure) - sets if the CDIM determines that the output circuit to the BCM is open or shorted to ground during normal operation.
This pinpoint test is intended to diagnose the following:
- Wiring, terminals or connectors
- Ignition switch
- CDIM
