Nissan Navara D40 vs NP300 Clock Spring: Part Number Guide

A Nissan Navara airbag light accompanied by a dead horn or steering-wheel controls often sends owners directly to a clock-spring listing. The pattern is relevant, but the Navara name covers different platforms and steering-column assemblies. D40, D40 ST-X/VSK and D23 NP300 listings can use very different reference numbers even when the product photos look similar.

This guide compares four catalogue routes—25560-JS40A, 25560-EC44D/EC48D, 25567-5X30A and 25554-3TS0A—and shows how to diagnose the circuit safely. It is designed to prevent the common mistake of ordering by model name and year range without checking the original connector and label.

Why Navara clock-spring listings overlap

The clock spring carries electrical circuits across the rotating steering interface. It may serve the driver’s airbag, horn, steering-wheel controls and, depending on configuration, components associated with steering-angle sensing. The internal ribbon cable is flexible but only across a defined number of turns.

Navara product searches often group vehicles by sale year, yet platform, body series, grade and market can change within that range. A D40 ST-X module described by 25567-5X30A should not be treated as the same unit as a D40 listing using 25560-JS40A, and neither should be treated as a D23 NP300 module using 25554-3TS0A without evidence.

Symptoms that deserve proper diagnosis

• Airbag or SRS warning with a driver-side circuit code
• Horn that works only at some steering angles
• Cruise, phone or audio buttons becoming intermittent
• Clicking or rubbing behind the steering wheel
• Multiple steering-wheel functions failing together
• A warning appearing after steering or dash work

Fitment and fault comparison

Reference	Common catalogue description	What to verify
25560-JS40A / B5567	Selected Navara D40 applications	Original label, sockets and steering-wheel equipment
25560-EC44D / EC48D	Selected D40 VSK applications	Market, build and connector geometry
25567-5X30A	Selected D40 ST-X 2011–2015 listings	ST-X configuration and original number
25554-3TS0A	D23 NP300 listings	Confirm the vehicle is D23, not D40

Use these patterns as evidence, not as a substitute for vehicle-specific service information. More than one fault can exist, especially after previous steering, electrical or cooling-system work.

A step-by-step diagnostic sequence

1. Separate the platform from the badge

Record whether the vehicle is D40 or D23 NP300, then add the VIN, build month, model grade and market specification. A registration year alone cannot resolve a change that occurred during production.

2. Read and preserve the SRS fault

Use a scan tool that communicates with the airbag module. Save the code and status before it is cleared. If only a horn or audio control fails with no SRS code, test that circuit rather than assuming the entire spiral cable is open.

3. Test the pattern through steering movement

With the vehicle stationary and using safe procedures, observe whether the affected non-airbag functions change as the wheel moves slightly. An intermittent pattern supports a rotating-interface fault, but damaged column wiring can still imitate it.

4. Inspect for previous work

Look for signs that the steering wheel, combination switch or rack has been removed. A clock spring installed off-centre can be torn when the wheel reaches full lock, even if the replacement part itself was new.

5. Photograph the original unit

Capture all labels, plug colours, locking tabs and the relationship between the clock spring and any steering-angle sensor. Compare these details with the exact product page before purchase.

6. Confirm calibration requirements

Some vehicles need steering-angle calibration or a specific self-learning sequence after the column assembly is disturbed. Do not road-test with active SRS or stability-system warnings.

Four RunningRoo product options to compare

These links are relevant catalogue options, not automatic fitment approval. Confirm the VIN, build date, original part number, connector or hose layout and required functions with RunningRoo or a qualified workshop before ordering.

1. Navara D40 clock spring 25560-JS40A / B5567 — For selected D40 applications after label and connector verification.

2. Navara D40 VSK clock spring 25560-EC44D / EC48D — A separate D40 reference route; compare both original numbers and hardware.

3. Navara D40 ST-X clock spring 25567-5X30A — A grade-specific listing for selected 2011–2015 ST-X vehicles.

4. Navara D23 NP300 clock spring 25554-3TS0A — For selected D23/NP300 applications—not a D40 substitute.

Installation details that prevent repeat failure

Set the front wheels straight and keep the steering shaft from moving before the wheel is removed. Use the clock spring’s shipping lock, centring window or specified turn-count procedure exactly as instructed. If the column or rack position is not known, resolve that alignment before fitting the new module.

After assembly, confirm free steering movement, horn and switch operation, then scan every relevant control unit. Complete steering-angle calibration where required and verify that SRS and stability warnings remain off after an ignition cycle and a controlled road check.

• D40, D40 ST-X/VSK and D23 NP300 are not one fitment
• Use the VIN and original label as primary evidence
• Compare every connector and locating feature
• Centre the steering system and the replacement module
• Use manufacturer-approved SRS handling procedures
• Scan and calibrate before returning the vehicle to service

Frequently asked questions

Is a D40 clock spring the same as an NP300 clock spring?

No general interchange should be assumed. D40 and D23 NP300 listings use different reference numbers and can have different connectors and attached functions.

What is the difference between 25560-JS40A and 25567-5X30A?

They are catalogue references associated with different selected D40 applications. Confirm the original label, grade, build data and connector layout before choosing.

Will replacing the clock spring clear the airbag light?

Only if the clock spring caused the stored fault and the rest of the circuit is sound. The code must be diagnosed, repaired and then cleared with an appropriate scan tool.

Why did a replacement clock spring break quickly?

Off-centre installation, an uncentred steering rack, incorrect fitment or unresolved connector damage can cause repeat failure. Inspect the installation evidence before fitting another unit.

Final recommendation

The safest Navara order starts with platform and part number, not a year-range shortcut. Distinguish D40 from D23 NP300, account for ST-X/VSK variations, match the original connectors and install the spiral cable at true centre.
