2000-2003 Montero Sport Cruise Control Module: Diagnosis and Replacement Guide
This guide covers the common failure symptoms, diagnostic steps, and replacement information for the cruise control module in 3.0L V6-equipped 2000-2003 Mitsubishi Montero Sport models.
- This module is for the cruise control system only, not the main Body Control Module (BCM).
- It is specific to 2000-2003 Montero Sport models with the 3.0L V6 engine.
- Replacement is plug-and-play and does not require any programming.
- Before replacing the module, always check fuses, the brake switch, and vacuum lines first, as these are common and simpler failure points.
Symptoms of a Failing Cruise Control Module
When the cruise control module in a 2000-2003 Montero Sport begins to fail, it typically results in the complete or partial loss of cruise control functionality. Before suspecting the module itself, it's wise to first check for simpler issues like a blown fuse or problems with the control switches.
- Cruise Control Will Not Engage: The most common symptom is that the system will not turn on at all. You might press the 'On' button, and the indicator light on the dashboard may or may not illuminate, but the system will not set a speed.
- Fails to Maintain Speed: The cruise control might engage but then fail to hold a consistent speed, either surging or gradually losing speed.
- System Disengages Randomly: You may be driving with the cruise control on, and it will suddenly shut off for no apparent reason.
- Dashboard Light On, But No Function: In some cases, the 'CRUISE' light on the instrument cluster will turn on, indicating the system has power, but it will not respond when you try to set or adjust the speed. This can point to a problem with the module, the switches, or the actuator.
Is This a Body Control Module (BCM)?
No. The part number MR490826 and its alternate, GOT16572M, refer specifically to the Cruise Control Module. It is a common point of confusion, but this is not the main Body Control Module (BCM), which Mitsubishi often calls an ETACS unit. The BCM controls a wider range of vehicle functions like power windows, door locks, and interior lighting. This module's sole responsibility is the cruise control system.
Compatibility Warning: This specific cruise control module is only for 2000-2003 Mitsubishi Montero Sport models equipped with the 3.0L V6 engine. It is not compatible with the 3.5L V6 engine, which uses a different part.
Known Issues, TSBs, and Recalls
As of early 2026, there are no specific recalls or Technical Service Bulletins (TSBs) issued by the National Highway Traffic Safety Administration (NHTSA) for the cruise control module itself on the 2000-2003 Montero Sport. Most issues are related to individual component failure due to age. Common related failures that can mimic a bad module include a faulty brake pedal switch (which is designed to disengage the cruise control), a defective clock spring in the steering column 🎬 Watch: Diagnose a faulty clock spring on a Montero, or cracked vacuum lines leading to the actuator.

Purchasing a used OEM cruise control module is a very common and cost-effective repair. Since these are relatively simple electronic units without complex programming, a tested, used part from a reputable supplier is a reliable option.
- Verify the Part Number: It is critical to match the part number exactly. Look for MR490826 or GOT16572M on the module's label.
- Inspect the Connector: Check the electrical connector pins on the used module. They should be clean, straight, and free of any green or white corrosion, which would indicate water damage.
- Check the Casing: Look for any cracks, signs of being pried open, or heat damage on the plastic casing.
- Why Used OEM is a Good Choice: Original Equipment Manufacturer (OEM) parts ensure perfect fitment and compatibility with your vehicle's wiring. For a part like this, where no programming is required, a used OEM unit offers the same performance as a new one at a fraction of the cost.
Programming and Installation
Pro Tip: No special programming or flashing is required when replacing this cruise control module. It is a plug-and-play component. The main Engine Control Module (ECM) may require VIN programming for other functions, but this separate cruise control unit does not.
The cruise control module is typically located in the driver's side footwell, mounted to the kick panel area. Replacement is straightforward for a DIY mechanic with basic tools.
- Disconnect the negative battery terminal.
- Locate the module in the driver's side kick panel area.
- Unplug the electrical connector.
- Unbolt the module from its mounting bracket.
- Install the replacement module, plug in the connector, and reconnect the battery.

Frequently Asked Questions (FAQ)
Do I need to program a replacement cruise control module?
No, the cruise control module for the 2000-2003 Montero Sport is a plug-and-play part and does not require any programming or dealer visit after installation.
Where is the cruise control module located?
The module is located behind the driver's side kick panel, to the left of the pedals.
Could a bad clock spring cause my cruise control to not work?
Yes. A faulty clock spring can interrupt the electrical connection to the cruise control switches on the steering wheel, preventing the module from receiving commands. If your horn or airbag light is also acting up, the clock spring is a likely suspect.
