Solutions for the flashing cruise light

The solutions for the flashing cruise light on your 2007 Subaru B9 Tribeca depend on the underlying cause of the issue. Here are some possible solutions:

Replace the brake light switch

One of the most common causes of the flashing cruise light is a faulty brake light switch. The brake light switch is a small switch located near the brake pedal that activates the brake lights when you apply the brakes. If this switch is faulty, it can cause the cruise light to flash. To solve this issue, you will need to replace the brake light switch. This is a relatively easy and inexpensive fix that can be done by a mechanic or a DIY enthusiast.

Check the throttle actuator control system

If the issue is not with the brake light switch, it could be with the throttle actuator control system. This system controls the throttle by adjusting the airflow to the engine. It is responsible for maintaining the speed set by the driver. If this system is not working properly, it can cause the cruise light to flash. To solve this issue, you will need to have your Subaru B9 Tribeca inspected by a mechanic. The mechanic will check the entire throttle actuator control system and fix any issues that are found.

Replace the cruise control switch

If the issue is not with the brake light switch or the throttle actuator control system, it could be with the cruise control switch itself. The cruise control switch is the button on your steering wheel that turns the cruise control system on and off. If this switch is faulty, it can cause the cruise light to flash. To solve this issue, you will need to replace the cruise control switch. This is a relatively easy and inexpensive fix that can be done by a mechanic or a DIY enthusiast.

If none of the above solutions work, it could be a problem with the ECM itself. The ECM is the brain of your vehicle's engine control system. It controls various systems, including the cruise control system. If the ECM is not working properly, it can cause the cruise light to flash. To solve this issue, you will need to have your Subaru B9 Tribeca inspected by a mechanic. The mechanic will check the ECM and fix any issues that are found.

This is a relatively easy fix that can be done by a mechanic or a DIY enthusiast.
