SLD Deadline 2026: Phase 1, 2 & 3 Explained | PasangSLD
Updated: July 2026 · Official source: JPJ portal
The SLD deadline is not one date — it is three phases based on your vehicle's year: 1 Oct 2025, 1 Jan 2026 and 1 Jul 2026 (Phase 3 now deferred, a grace period). 'Deferred' does not mean safe: 8,924 investigation notices have already been issued, and compliance sits at just 15%. Here is the full timeline and what the deferment really means.
1. The Three-Phase Timeline
Phase 1 — 1 Oct 2025: vehicles from 2015 onwards verify SLD functionality (90 km/h cap, warning at 85, UN R89). Phase 2 — 1 Jan 2026: pre-2015 vehicles, activation via the ECU. Phase 3 — 1 Jul 2026: pre-2015 vehicles without ECU support, full retrofit — full enforcement deferred.
Takeaway: identify each vehicle's year of manufacture first — it determines the phase and the type of work.
2. What 'Deferred' Actually Means
Not a cancellation — the requirement stands; only blanket compounds are not yet enforced. The proof: 8,924 Section 114 investigation notices were issued between Oct 2025 and Mar 2026. Vehicles without an SLD can still be investigated and put on record.
No new full-enforcement date has been announced so far — check JPJ's official website for updates.
Takeaway: the grace period is a chance to install calmly, not an exemption.
3. Compliance at 15% — Why Slots Are Filling Up
Only ~15% of 513,679 vehicles were compliant as of Mar 2026 — hundreds of thousands of lorries and buses are not. Once full enforcement is re-announced, everyone will scramble for the same recognised workshop slots, and every installation takes time (wiring, calibration, documentation).
Takeaway: book early while demand is manageable — flexible dates, unhurried work.
4. Which Vehicle, Which Phase
Scope: goods lorries above 3,500 kg, express/tour/factory/school buses, prime movers & trailers.
— 2015 onwards: most already have a factory-fitted SLD — verification only — Pre-2015 with a supported ECU: activation (Phase 2) — Pre-2015 without support: retrofit (Phase 3)
Takeaway: confirm each fleet vehicle's year and ECU compatibility — these two factors determine the work and the cost.
5. Cost, Slip & Next Steps
Market rates: advertised packages RM400–600; real quotes can reach RM1,700–2,500 depending on device grade, ECU, wiring and calibration. After installation: the SLD Functionality Verification Slip — valid 2 years, checked at PUSPAKOM.
Being transparent: PasangSLD is not on JPJ's official supplier list — we are the coordinator who arranges your installation with recognised workshops, matches your location and makes sure documentation is complete.
Takeaway: WhatsApp us your vehicle type, year and location today — the earlier you start, the more workshop and date options you have.
Summary — SLD Checklist
- Confirm the year of manufacture for every vehicle in your fleet.
- Check whether the ECU supports activation or a full retrofit is needed.
- Ask for a written quote stating the device grade and scope of work.
- Book a JPJ-recognised workshop slot as early as possible.
- Keep the SLD Functionality Verification Slip in every vehicle.
- Note the slip renewal date — it is only valid for 2 years.
- WhatsApp PasangSLD to check your phase and arrange installation.
FAQ
When is the actual deadline to install an SLD?+
It depends on the phase: 1 Oct 2025 (2015-and-newer vehicles, functionality verification), 1 Jan 2026 (pre-2015, ECU activation), 1 Jul 2026 (pre-2015, retrofit). Full Phase 3 enforcement is deferred for now, but the installation requirement still stands.
If Phase 3 is deferred, can I wait first?+
You can, but it is risky. JPJ has already issued 8,924 Section 114 investigation notices (Oct 2025–Mar 2026), and once full enforcement is announced, workshop slots will fill up fast — only around 15% of vehicles were compliant as of Mar 2026.
How much does SLD installation cost now?+
Entry packages are advertised at around RM400–600, but real quotes can reach RM1,700–2,500 depending on device grade, ECU compatibility, wiring, calibration and documentation. Ask for a quote specific to your vehicle.
Is PasangSLD an official JPJ supplier?+
No. JPJ has an official retrofit supplier list, and we are not on it. We are the coordinator — we arrange your installation with JPJ-recognised workshops and suppliers, and handle the slot and documentation.
