2026 Ram/Dodge Clock Spring Guide: DTC Mapping, CAN-Bus 3.0 Compliance & OEM-Grade Replacement Without Heated Steering Wheel
Your Ram's airbag light is on, the horn cuts out, and the cruise buttons go dead — three symptoms, one rotating connector behind the wheel. The Clock Spring Without Heated Steering Wheel Fits 1500 2500 3500 Laramie Viper (Koeep PN: KS-RAM-CS-NH) is the direct-fit replacement, engineered to 2026 OEM material and protocol benchmarks.
This variant omits the heated wheel ribbon circuit on purpose. Fewer circuits mean fewer failure points. If your truck carries the factory heated steering wheel (sales code NHS or NHA), order the heated variant instead — Koeep PN: KS-RAM-CS-H.
Fitment: Trucks and Years Covered
Coverage runs the full pre-facelift and Classic body range: Ram 1500, 2500, and 3500 from 2013 through 2025.5, including Laramie trims, plus the Dodge Viper SRT for 2013–2017. The unit is fully backward-compatible with 2013–2024 model-year Rams.
It cross-references four Mopar numbers — 68141880AA, 68141880AB, 68141880AC, and 68222854AA — plus aftermarket equivalents Dorman 525-600 and Standard Motor Products CSP119. Match one against your failed unit before ordering.
Material Science: Why This Build Outlasts the Original
Glass-fiber PBT housing, 150°C continuous rating
The housing is 30% glass-fiber-reinforced PBT (polybutylene terephthalate) rated for 150°C continuous service. It replaces the PA66 (nylon-66) housings that embrittled in trucks operating in extreme Southwest and Middle Eastern climates.
Adhesive-less polyimide ribbon, >500,000 cycles
Inside sits a high-cycle polyimide (Kapton-type) flexible printed circuit with adhesive-less lamination. That process eliminates the delamination failure modes documented in NHTSA ODI complaints for 2014–2018 Ram trucks. The ribbon is rated past 500,000 rotational cycles, tested at 25°C and 85°C — the OEM minimum is 300,000.
Gold over nickel on beryllium copper
Contacts are gold-plated beryllium-copper with a nickel barrier. Contact resistance stays below 10 mΩ after environmental cycling per ISO 16750-4. Tin-plated aftermarket contacts cause the intermittent high-resistance faults in the B0001–B0004 range; this plating stack removes that failure mode.
Standards behind KS-RAM-CS-NH: ISO 26021:2026-grade pyrotechnic circuit integrity for Stage 1 & Stage 2 airbag loops, SAE J2344 verification, IPC-6013 Class 3 flexible circuit qualification, SAE/USCAR-2 Rev.7 terminal performance, and ISO 16750-4:2026 validation (−40°C to +125°C, 1,000 hours damp heat at 85°C/85% RH).
DTC Map: What This Unit Triggers and Clears
Pull codes before you disassemble anything. Five map directly to clock spring faults on this platform:
- B0001-1A — Driver Stage 1, resistance too low
- B0002-1A — Driver Stage 2, resistance too low
- B0003-11 — Stage 1, short to ground
- B0004-12 — Stage 2, short to battery
- U0151-00 — lost communication with ORC
Primary coverage spans B0001-00 through B0004-96 — all driver airbag deployment loop sub-types — plus U0151-00, U0140-00 (lost communication with BCM, steering column module variant), and B1C2D-00 (steering wheel switch circuit performance, LIN-bus specific).
The payoff after a correct install: most B0001–B0004 codes clear automatically on the next ignition cycle, no scan tool needed, as long as every connector is fully seated.
Specification Table: KS-RAM-CS-NH vs 2026 Benchmark
| Specification | Koeep KS-RAM-CS-NH | Industry Benchmark (2026) |
|---|---|---|
| Ribbon material | Polyimide FPC (adhesive-less laminate) | ISO 26021 Class A flexible circuit |
| Contact plating | Au (gold) over Ni (nickel) barrier, BeCu substrate | SAE J2344 terminal durability ≥50 mating cycles |
| Cycle life | >500,000 rotational cycles (tested at 25°C & 85°C) | OEM minimum: 300,000 cycles |
| Heated wheel circuit | Not included (simplified 4+2 ribbon layout) | Optional; 6+2 or 8+2 ribbon for heated variants |
| CAN protocol support | CAN FD (up to 5 Mbps) & LIN 2.2A backward-compatible | SAE J2284-5 (CAN FD for 2026+ light-duty vehicles) |
| Housing material | 30% GF-PBT, UL94 V-0 rated | USCAR-2 Class 3 temperature range (−40°C to +125°C) |
| Airbag loop resistance | 2.0–3.5 Ω (nominal ±0.3 Ω per loop) | FMVSS 208: loop resistance <5.0 Ω threshold |
| Vehicle compatibility | Ram 1500/2500/3500 (2013–2025.5), Laramie, Viper SRT (2013–2017) | OEM PN cross: 68141880AA, 68141880AB, 68141880AC, 68222854AA |
Note the resistance row: FMVSS 208 caps loop resistance at <5.0 Ω, and this unit measures 2.0–3.5 Ω nominal (±0.3 Ω per loop). That margin keeps the Stage 1 and Stage 2 loops passing integrity checks.
Installation Notes That Prevent Comebacks
The squib latch needs a double-click
The clockspring-to-ORC squib connector is where most installs go wrong. The 2026-compliant latching mechanism on this unit requires an audible double-click before you count it seated.
Airbag light still on after install?
That is a connector latch engagement issue at the squib connector in nearly every case. Disconnect, inspect for bent pins, reseat firmly. Pinout: pin 1 = Stage 1+, pin 2 = Stage 1−, pin 3 = Stage 2+, pin 4 = Stage 2−.
If a code survives three ignition cycles, clear it manually with a compatible scan tool — Autel MS909, Snap-on ZEUS+, or wiTECH 2.0. Rarely necessary.
Steering angle sensor: reuse and calibrate
The SAS is not included — it mounts separately on the truck. Reuse your existing unit and recalibrate it after the swap.
One Architecture, Two Platforms: Ram and Viper SRT
The Viper SRT (2013–2017, ZB II platform) and the Ram 1500/2500/3500 (DS/DJ/D2 platform) share the same Mopar clock spring architecture. Numbers 68141880AA through 68141880AC, plus 68222854AA, cross-reference to both platforms.
Every Viper of that generation shipped without a heated wheel, so the non-heated variant is the default correct fitment across the whole run.
Other Platforms, Same Approach
Koeep stocks matched clock springs for other marques, both following the same heated-versus-non-heated logic:
- For 08-14 Hyundai Genesis Without Heated Steering Wheel Clock Spring 93490-3M000 — the non-heated unit for 2008–2014 Genesis.
- For 14-16 Kia Cadenza Optima W/ Heated Steering Wheel Clock Spring 93490-3R325 — the heated variant for 2014–2016 Cadenza and Optima.

Shop the Clock Spring — No Heated WheelFAQ: Failure Patterns, Fitment, and Post-Install Behavior
Why does my 2020 Ram 1500 Laramie show code B0001-1A but the airbag light only comes on intermittently?
Intermittent B0001-1A on 2019–2024 Rams with the original clock spring traces to micro-fractures in the ribbon at the 9-o'clock and 3-o'clock steering positions — the most common rest angles for these trucks. The adhesive-less polyimide FPC in this replacement eliminates that failure mode; pending B0003-11 and B0004-12 alongside B0001-1A point to ribbon degradation, not a connector issue.
Will this clock spring work on a 2025 Ram 2500 with the 12-inch Uconnect display?
Yes. The CAN FD pass-through is fully transparent to the Uconnect 5 (UAQ/UAS) infotainment bus, and the LIN 2.2A-compatible control circuit handles the 12-inch display's switch matrix without latency. One check first: the truck must not carry the factory heated steering wheel (sales code NHS or NHA) — heated trucks need KS-RAM-CS-H.
After installation, my horn and cruise control work but the airbag light stays on — what now?
Almost always a connector latch engagement issue at the clockspring-to-ORC squib connector. The latch needs an audible double-click. Disconnect, inspect for bent pins (pin 1 = Stage 1+, pin 2 = Stage 1−, pin 3 = Stage 2+, pin 4 = Stage 2−), and reseat firmly. If a code survives three ignition cycles, clear it manually with Autel MS909, Snap-on ZEUS+, or wiTECH 2.0 — rare, but possible.
Is the Dodge Viper SRT clock spring truly the same part as the Ram truck unit?
Functionally identical. The Viper SRT (2013–2017, ZB II platform) and the Ram 1500/2500/3500 (DS/DJ/D2 platform) share the same Mopar clock spring architecture — 68141880AA through AC and 68222854AA cross-reference to both. Vipers universally lack a heated wheel, so the non-heated variant fits every Viper of that generation.
Does this part support a heated steering wheel?
No. This variant omits the heated wheel ribbon circuit, which reduces failure points. Check the build sheet for sales code NHS or NHA — if either appears, order the heated variant, Koeep PN: KS-RAM-CS-H.
Does the clock spring include the steering angle sensor?
No. The SAS mounts separately on the vehicle. Reuse or calibrate your existing sensor after the clock spring is in place.
Will the B0001–B0004 codes clear themselves after I install it?
In most cases, yes — codes clear automatically on the next ignition cycle provided every connector is fully seated. Only a code that survives three ignition cycles needs a manual clear with a scan tool such as the Autel MS909, Snap-on ZEUS+, or wiTECH 2.0.
What model years does this clock spring cover?
Ram 1500, 2500, and 3500 from 2013 through 2025.5 — pre-facelift and Classic body styles — plus Laramie trims and the Dodge Viper SRT for 2013–2017. Fully backward-compatible with 2013–2024 Rams and compliant with the updated NHTSA FMVSS 208 interconnect requirements.
