ALTBET OBD2 Bypass Cable for 2018–2020 Dodge Cummins RAM 1500/2500 — OEM-fit Reusable Security Gate Bypass

ALTBET's Security Gate Bypass OBD2 Cable lets you temporarily bypass the factory security gate on 2018–2020 Dodge Cummins RAM 1500 and 2500 trucks without permanent modification.

When you need to connect diagnostic tools or programmers to a RAM Cummins truck that has an OBD2 security gate, a reusable bypass cable simplifies access while keeping the vehicle unchanged.

How does this cable work with 2018–2020 Dodge Cummins RAM models?

The ALTBET bypass cable replicates the vehicle-side connections blocked by the manufacturer’s security gate, restoring a direct path for OBD2 communications while connected. It is made to match pinouts used in many late-model RAM trucks, ensuring reliable signal transfer for tools that require full access.

• Matches OEM connector shape and pin layout for compatibility
• Designed to restore standard OBD2 signals when attached
• Works with common diagnostic, tuning, and flashing devices

Is the cable permanent or reusable — and how durable is it?

This ALTBET cable is a non‑permanent, reusable solution intended for temporary connection rather than permanent installation. It is constructed with reinforced wiring and robust connectors to withstand repeated plug‑in cycles and workshop use.

• Reusable design — plug in, perform work, unplug and store
• Sturdy housing and strain relief for long service life
• Not intended as a weatherproof or externally mounted permanent adapter

What should I check before ordering to ensure compatibility?

Verify your truck’s model year and engine fitment: this product is specifically made for 2018–2020 Dodge Cummins RAM 1500 and 2500 models. Check the physical shape of your OBD connector and consult any device manuals to confirm that a cable-based bypass is appropriate for your diagnostic or tuning hardware.

• Confirm vehicle year and Cummins engine trim (2018–2020 RAM 1500/2500)

How is this cable typically used in a workshop or at home?

Technicians and informed car owners use the cable to temporarily enable full OBD2 access while running diagnostics, software updates, or performance tuning. After work is finished, the cable is removed so the vehicle returns to its original, unmodified state.

• Plug into the truck’s OBD2 port to connect scanners or programmers
• Perform reads, writes, or real-time monitoring, then disconnect
• Store the cable safely; reuse for future service intervals
