2001-2004 Subaru Legacy & Outback 3.0L H6 Cruise Control Module: Recall, Diagnosis, and Replacement
This guide covers the specific cruise control module for 3.0L H6 engines, clarifying common confusion with the Body Control Module and detailing a critical safety recall.
- This module (part #87022AE13A) is ONLY for 3.0L H6 engines in the 2001-04 Legacy/Outback and 03-04 Baja.
- A used module is a great option because NO programming or dealer visit is required for installation.
- A flashing cruise light with a check engine light means the system is disabled due to an engine fault; diagnose the engine code first.
- Check if NHTSA safety recall 04V-128 has been performed to prevent a stuck throttle cable.
Important: This is NOT a Body Control Module
Compatibility Warning: This cruise control module, part number 87022AE13A, is exclusively for the 2001-2004 Subaru Legacy, 2001-2004 Subaru Outback, and 2003-2004 Subaru Baja models equipped with the 3.0L H6 engine. It will not work on models with the 2.5L 4-cylinder engine, which use a different part. This part is often misidentified as a Body Control Module (BCM). The actual BCM in these Subarus is called the Body Integrated Unit (BIU), which controls features like power windows, door locks, and the immobilizer system. This cruise control module is a separate, single-purpose part.
Symptoms of a Failing Cruise Control Module
Failure of the cruise control module can manifest in several ways. Sometimes the issue is the module itself, but often, other related problems can cause similar symptoms.
- Cruise control will not turn on: The "CRUISE" indicator light on the dashboard does not illuminate when the main button is pressed.
- Cannot set a speed: The system turns on, but pressing the "SET" switch does not engage the cruise control.
- Cruise control disengages randomly: The system may work for a while but then suddenly turn off without the driver touching the brake, clutch, or cancel switch.
- Incorrect speed holding: The vehicle may fail to maintain the set speed, either losing speed or surging.
The Flashing Cruise Light and Check Engine Light
One of the most common issues reported by Subaru owners is a solid Check Engine Light (CEL) accompanied by a flashing "CRUISE" light on the instrument cluster. This is a built-in safety feature. When the vehicle's main computer (ECU) detects any fault that triggers the Check Engine Light, it automatically disables the cruise control system as a precaution. The flashing cruise light is simply an indicator that the system is disabled; it does not necessarily mean the cruise control module itself has failed. Common causes for this condition include:
- A loose or faulty gas cap
- A failing oxygen (O2) sensor
- Engine misfires
- A dirty Mass Airflow (MAF) sensor
Pro Tip: If you have a flashing cruise light and a solid CEL, the first step is to diagnose the Check Engine Light code using an OBD-II scanner. Resolving the underlying engine issue will typically restore cruise control function without needing to replace any parts in the cruise system.

NHTSA Recall 04V-128 (Subaru Campaign WWQ-01)
A significant safety recall was issued for all 2001-2004 Subaru Legacy and Outback models with the 3.0L H6 engine. The recall addresses a condition where the cruise control cable could detach from its track on the throttle lever and get caught. If this happens, the throttle can become stuck open and will not return to idle when the driver releases the accelerator pedal, potentially causing a loss of vehicle control. This can occur even when the cruise control is not in use.
The official remedy was for Subaru dealers to install a small retaining clip on the cruise control lever tab to prevent the cable from ever becoming dislodged. Before purchasing a vehicle or troubleshooting the cruise system, it is wise to check with a Subaru dealer or use the NHTSA VIN lookup tool to see if this free recall service was performed.
Buying a Used Cruise Control Module
Because this module is a simple electronic unit without any complex programming, a used OEM part is an excellent and cost-effective solution. New OEM modules have been discontinued, making used parts the primary option.
Key Considerations:
- No Programming Required: This is the most important factor. Unlike the Body Integrated Unit (BIU), this cruise control module is plug-and-play. It does not need to be programmed, flashed, or matched to your vehicle's VIN. Installation is as simple as swapping the part.
- Verify the Part Number: Ensure the used module you are buying is part number 87022AE13A. While other modules may look similar, they are not compatible.
- Confirm the Donor Vehicle: Double-check that the part was removed from a Legacy, Outback, or Baja with the 3.0L H6 engine.
- Inspect for Damage: Check the plastic housing for cracks and ensure the electrical connector pins are straight and free of corrosion. Water damage is a potential concern for any interior electronic module, so look for any signs of moisture or rust.
Replacement Procedure Overview
Replacing the cruise control module is a straightforward job suitable for a DIY mechanic with basic tools.
- Difficulty: 2/5
- Estimated Time: Less than 1 hour
- Location: The module is located in the passenger footwell, typically mounted to the right of the glove box or up under the dashboard. You will need to remove the glove box or a lower trim panel to access it. 🎬 Watch this walkthrough on removing the glove box and interior modules.
- Steps:
- Disconnect the negative terminal from your vehicle's battery.
- Remove the glove box assembly and any necessary trim panels to gain clear access to the module.
- Carefully unplug the electrical harness connector from the module.
- Unbolt the module from its mounting bracket (typically one or two 10mm bolts).
- Install the new module, reconnect the electrical harness, and reassemble the dashboard.
- Reconnect the battery and test for proper function.
Cost of Replacement
The cost to fix a faulty cruise control system can vary widely depending on the cause. If the module itself is the problem, using a recycled part is very affordable.
| Part Source | Estimated Cost |
|---|---|
| New OEM | Discontinued |
| New Aftermarket | Not Available (only full conversion kits exist) |
| Used OEM | $40 - $75 |
| Shop Labor (Module Replacement) | $70 - $100 |
Frequently Asked Questions (FAQ)
Does a replacement cruise control module need to be programmed by a dealer?
No. For the 2001-2004 Legacy and Outback 3.0L H6, the cruise control module (87022AE13A) is a plug-and-play part and does not require any programming or dealer visit. This is often confused with the Body Integrated Unit (BIU), which does require programming for key and immobilizer data.
Why is my cruise control light flashing and my check engine light on?
This is a safety feature. Subaru disables the cruise control system whenever a fault triggers the check engine light. The flashing cruise light indicates it's disabled. You must diagnose and fix the engine code first; the problem is likely not with the cruise control system itself.
My cruise control doesn't work, but there are no warning lights. What should I check first?
First, check the simple things. Ensure the main cruise switch is on. Then, check the associated fuses. A common and often overlooked cause is a faulty brake light switch or clutch switch (on manual transmissions). These switches are designed to cancel the cruise control, and if one fails, it can prevent the system from engaging at all.

The recall (NHTSA 04V-128) was for a mechanical issue, not the electronic module. The cruise control's throttle cable could get stuck, preventing the engine from returning to idle. The fix was a simple clip installed by the dealer. You should verify this recall has been performed on your vehicle.
