SSM 52174 - 2022-2023 Navigator - DTC B1471:13 Stored In SCMG And/Or SCMH After Reprogramming

Some 2022-2023 Navigator vehicles may exhibit diagnostic trouble code (DTC) B1471:13 setting in the Seat Control Module-G (SCMG) and/or Seat Control Module-H (SCMH) after module reprogramming or replacement. This may be due to the module configuration. To correct the condition, perform the SCMG - Driver Multi-Contour Seat Module (SCMG) and/or SCMH - Passenger Multi-Contour Seat Module (SCMH) Configuration application on the module storing the DTC using the latest level of the Ford Diagnosis and Repair System (FDRS). For claiming, use causal part 14F548 and applicable labor operations in Section 10 of the Service Labor Time Standards (SLTS) Manual.


Supplemental information from the 2022-2024 Navigator Workshop Manual on the above-referenced Seat Control Modules...

SCMG
The SCMG controls the operation of the driver multi-contour seat. The SCMG communicates to the front seat cushion adjuster and front seat backrest adjuster through a IN . The SCMG controls the air pump which supplies air pressure necessary to be diverted to the applicable air bladders/bolsters as required for the desired mode(s) of operation. PMI is required when a new SCMG is installed. The SCMG communicates on the MS-CAN .

SCMH
The SCMH controls the operation of the driver multi-contour seat. The SCMH communicates to the front seat cushion adjuster and front seat backrest adjuster through a LIN . The SCMH controls the air pump which supplies air pressure necessary to be diverted to the applicable air bladders/bolsters as required for the desired mode(s) of operation. PMI is required when a new SCMH is installed. The SCMH communicates on the MS-CAN .

Multi-Contour Seat Operation

The multi-contour seats are independently controlled by the FDIM (touchscreen). The driver and passenger front seats each contain a total of 21 inflatable bladders: 4 cushion bladders, 2 cushion side bolsters, 3 backrest lumbar bladders, 10 upper backrest bladders and 2 backrest side bolsters. The pressures for the lumbar bladders, cushion bolster pair and backrest bolster pair are displayed on the FDIM as a percentage of the maximum pressure.

There are 2 modes of operation: adjust or massage. Adjust mode allows pressure changes in one of the 3 lumbar bladders and 2 sets of bolsters to be inflated or deflated to a desirable feel. Massage mode provides a sequence of inflation and deflation of the upper backrest, lumbar and cushion bladders to simulate a massage motion.

NOTE: Refer to the Owner's Literature for information how to select the various modes using the touchscreen buttons.

When in Adjust mode:

• Each tap of the up or down buttons cycles through the following bladders and bolsters: Upper lumbar, middle lumbar, lower lumbar, back bolster and cushion bolster.
• When the inflate/deflate buttons are pressed (or held), the pressure increases or decreases for the currently selected bladder or bolster pair.
• Pressing the mode select button toggles the seat to massage mode. The ignition must be on for massage mode to function.

NOTE: The passenger multi-contour seat will not enter massage mode unless the passenger seat is occupied (or has greater than 9.07 kg (20 lb) on the seat cushion).

When in Massage mode:

• Each tap of the up or down buttons cycles between backrest and cushion massage modes.
• Each tap of the inflate/deflate buttons cycles between the intensity levels of massage (off, low and high).
• Pressing the mode select button toggles the seat to adjust mode. Middle lumbar bladder will be selected automatically.

Each multi-contour seat can be restored to the original factory settings by pressing and holding the select button greater than 30 seconds. This resets all the adjust and massage settings (including any multi-contour driver seat settings associated to memory personality 1, 2 or 3).
