WARNING: This page is about a different car, the 2013 Ford F-550 Super Duty, 2013 Ford F-450 Super Duty, 2013 Ford F-350 Super Duty, and 2013 Ford F-250 Super Duty. 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
