RE:
Seat Slide Sensor Wiring Harness Damage Under Driver’s Seat
TIN Number:
TIN-20-52A-002
AFFECTED VEHICLES: 2013 – 2020 (ZC) Outlander Sport
PURPOSE:
MMNA has identified warranty claims for SRS DTCs B1558 “OCM DTC Present” and B1556 “Driver’s Seat
Slide Sensor Malfunction” with OCM DTC B1B8D “Driver’s Seat Slide Sensor Open Circuit”. Additional OCM
DTCs that may also be present are: B1B8C “Driver's Seat Slide Sensor Circuit Performance” and B1B8E
“Driver's Seat Slide Sensor Short Circuit”.
During diagnosis for this
condition, dealers should check
for damage to the driver’s seat
slide position sensor harness. If
a damaged harness is found, DO
NOT replace the front seat
adjustor or SRS ECU for this
condition. Please replace the
seat harness with the counter
measured part listed in the
parts information section below.
NOTE: In MUT-III, the DTC B1556
(in SRS ECU) currently has the description “PS.seat position SW fail”. B1556 represents an issue with the
driver’s seat.
Additionally, wiring for the seat belt buckle switch, heated seat, and power seat motor (if equipped) are
found in the same under-seat location as the harness for the driver’s seat slide sensor.
MMNA has identified claims for inoperative function or DTCs for the seat belt buckle switch (SRS DTC
B1527 [Open], or B1528 [Short]), heated seat, and power seat motor that could also be related to wiring
concerns under the driver’s seat area. These components are not serviced with the front seat adjustor and
are available separately, as identified in CAPS. Please inspect these harnesses if inoperative functions or
DTCs exist for the driver’s seat belt buckle switch, heated seat, and/or power seat.
Parts information: Harness tube of the seat slide sensor was changed to improve its durability as of May
22nd, 2020 (VIN:JA4AP4AU5LU031440).
