Multifunction Electronic Modules: Removal & Installation Ford Focus II facelift

REMOVAL

Note. Electronic modules are sensitive to static electrical charges. If exposed to these charges, damage to the module may result.

Note. Prior to the replacement of the module, it is necessary to upload the module configuration information to a scan tool. This information must be downloaded into the new smart junction box (SJB) after installation. For additional information, refer to MODULE CONFIGURATION article. In the event that As-Built data is required (SJB will not communicate), all remote keyless entry (RKE) devices must be programmed to the new SJB. A minimum of 2 devices are necessary to complete the configuration and turn off the flashing interior lights.

Note. The tire pressure monitoring system (TPMS) functionality is integral to the SJB.

Note. A new SJB is delivered in a "manufacturing mode" with 7 pre-set DTCs. A successful configuration of the SJB, then a successful TPMS sensor training, then a successful self-test including the clearing of all DTCs is required in order to clear the 7 manufacturing mode DTCs. The 7 manufacturing mode DTCs are: B106D (Tire Pressure Monitor System [TPMS] Initiators Not Configured) This DTC is present when the SJB is not configured, even on applications that are not equipped with initiators. B2477 (Module Configuration Failure) B2868 (Left Front Tire Pressure Sensor Fault) B2869 (Right Front Tire Pressure Sensor Fault) B2870 (Right Rear Tire Pressure Sensor Fault) B2871 (Left Rear Tire Pressure Sensor Fault) C2780 (ECU in Manufacturer Sub-State)

1. Upload the module configuration information from the SJB into the scan tool. For additional information, refer to «MODULE CONFIGURATION»(ref-357143) article.
2. Disconnect the 7 electrical connectors.
3. Remove the 3 nuts and the SJB.

INSTALLATION

1. Position the SJB and install the 3 nuts. Tighten to 4 Nm (35 lb-in).
2. Connect the 7 electrical connectors.
3. Download the SJB configuration information from the scan tool to the SJB. For additional information, refer to «MODULE CONFIGURATION»(ref-357143) article.
4. Train the tire pressure sensors. For additional information, refer to «WHEELS AND TIRES»(ref-357130) article.
5. Carry out the SJB self-test (must include an on-demand self-test) and then repeat the self-test to confirm all DTCs have been cleared.
6. Rotate the instrument panel dimmer switch from the full dim position to the dome ON position. This will make sure that all displays are visible under all lighting conditions.
