WARNING: This page is about a different car, the 2008 Ford Pickup, 2008 Ford F550 Super Duty, 2008 Ford F450 Super Duty, and 2008 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 input from the ignition switch and provides a RUN/ACC output to the Smart Junction Box (SJB). The CDIM has micro-processors that continually monitor these inputs and outputs. If a circuit failure is detected, the applicable DTC will be set.
- B1355 Ignition Run Circuit Failure - If the CDIM determines that the input circuit from the ignition switch is open or shorted to ground during normal operation, DTC B1355 will be set.
- B1359 Ignition Run/ACC Circuit Failure - If the CDIM determines that the output circuit to the SJB is open or shorted to ground during normal operation, DTC B1359 will be set.
This pinpoint test is intended to diagnose the following:
- Wiring, terminals or connectors
- Ignition switch
- CDIM
