Full Specification Table

Every value below comes from the unit's published cross-reference data and end-of-line testing. Use it for procurement checks or to compare against your scan-tool readouts.

Fitment Check Before You Order

Two WK2 clock springs can look identical and still be wrong for your car. Heated-wheel models use a 12-pin SCCM connector; non-heated models use 8 pins. Count the pins behind your wheel before ordering the Koeep 12-pin heated variant — the two are not interchangeable.

On supersession: Mopar replaced 68141864AA/AB/AC with 68141864AD in 2025. This unit is backward and forward compatible across the whole set, and it meets or exceeds the Dorman, SMP, and Crown equivalents in cycle life and temperature rating.

Material and Signal Integrity: What 2026 Demands

Ribbon and conductors

The laminated ribbon stacks six traces: two for the airbag squib, one for the horn, two for the MFS, and one for the heated wheel. Conductors are OFHC (oxygen-free high-conductivity) copper with ENIG (electroless nickel immersion gold) contact pads, which removes the tin whisker risk addressed by JEDEC JESD22-A121.

Kapton (PI) film insulation, 0.025mm thick, survives continuous flex from −40°C to +125°C. Cycle life clears the 1,000,000-rotation benchmark under SAE J2223 for steering column ribbon cables.

Housing

The housing is molded from PET-GF30, a 30% glass-fiber-reinforced polyethylene terephthalate with a tensile modulus over 9,200 MPa. It resists warpage under sustained 125°C exposure and carries a UL94 V-0 flame class. Halogen-free PET-GF30 is mandatory under the 2026 revision of EU ELV Directive 2000/53/EC Annex II — this unit complies out of the box.

Heated circuit and steering angle sensing

A dedicated Kelvin-sense 4-wire trace handles resistance-temperature detection (RTD) on the heated circuit, which prevents nuisance thermal-cutoff events and false open-circuit codes during thermal cycling.

The SCCM-integrated steering angle sensor uses GMR (giant magnetoresistive) sensing at 0.1° resolution. That precision keeps it compatible with 2026 ADAS re-calibration workflows, which are required after any clock spring replacement.

DTC Mapping: What Each Code Means

WK2 clock spring failures surface across three modules: the SRS airbag module, the SCCM, and the HSWM (Heated Steering Wheel Module). Here is the map.

• B1B02–B1B09 — driver airbag squib faults: open circuit, short to ground, short to battery, resistance too high or low.
• B0001-49 / B0002-49 — frontal deployment control internal electronic failure.
• C0051-49 — steering angle sensor internal fault.
• B1C6A-13 — heated steering wheel circuit open.
• B1C6B-11 — heated steering wheel circuit short to ground.
• U0140 / U0141 — secondary lost-communication codes: SCCM to BCM and SCCM to IPM.

2026 scan tools may report enhanced U-codes for SCCM CAN timeout. All of them clear once you run the SCCM re-zero and SRS module reset procedures. Each unit is end-of-line tested for squib loop resistance, heated circuit loop resistance, and SAS GMR output linearity (±0.1° across ±740°).

Related WK2 Parts Worth a Look

If the steering column area is already apart, check the rest of the front end. For 2011–2015 Grand Cherokee builds, Koeep carries a 2X Front Left and Right Side Steering Knuckle that covers both sides in one order.

A worn rim makes every steering fault feel worse. The Premium Hand-Stitched Leather Steering Wheel Cover for Jeep Grand Cherokee is a direct way to refresh the wheel you grip every day.

Cooling is the other known WK2 pressure point — our guide to the Aluminum Radiator CU13200 covers the 2011–2014 Dodge Durango and Jeep Cherokee. For everything else, browse the full steering and suspension catalog at Koeep.
