SHLPDFM YWB500220 Air Suspension Relay Module 12V

This pair of air suspension compressor relay modules is designed to restore reliable operation to the air suspension circuit on a range of Land Rover and Range Rover models, offering a straightforward, direct-replacement option that reduces downtime. With a compact form and plug-in fit, the relays make it easier to get the compressor switching back to normal operation after a relay failure.

Key Points

The relays are sold as a set of two, matching the standard equipment layout used on many models. They are intended to act as a direct swap for the original relay unit, which helps keep installation simple and reduces the need for modifications. According to the manufacturer, these modules use a 12 volt coil and have a nominal current rating of 70 amps, which is suitable for the high current draw of air suspension compressors. ⚙️

Compatibility covers several model years across the Land Rover and Range Rover range, including Discovery and Range Rover Sport variants produced in the mid 2000s and early 2010s. The parts are presented as OE-style replacements and are useful when the existing relay shows signs of heat damage, unreliable switching, or contact wear. Consider that fitment can vary by region and model sub-variant, so verify compatibility with vehicle records or a mechanic before installation.

Usage Recommendations

Installation is typically a matter of unplugging the old relay and fitting the new unit into the original socket, which keeps the need for additional wiring to a minimum. For safety, isolate the vehicle battery before beginning work and reconnect only after the relays are seated and any connector clips are secured. If the vehicle has a history of compressor motor issues, check the compressor and wiring concurrently because replacing the relay alone will not fix an underlying motor fault. 🔧

Be aware that, according to the manufacturer, these relays conform to OE-style specifications but aftermarket units can differ slightly in housing or terminal layout. If electrical symptoms persist after fitting these modules, further diagnostic work will be required to identify any intermittent faults or control module faults.
