The most common reasons a 1999 Suzuki Swift cruise control isn't working are failed control module, sensor or switch issues, or throttle actuation problems.
  • Sensor: A faulty sensor can lead to incorrect readings, causing issues with engine performance or triggering warning lights on the dashboard.
  • Control Module: A faulty control module can result in erratic vehicle behavior or failure of various electronic systems due to improper signal processing.
  • Throttle: A faulty throttle body or a defective accelerator pedal position sensor may be causing inconsistent acceleration and poor engine response.
Proper diagnosis will determine the exact cause of your symptom, saving you money on unnecessary repairs. The diagnostic experts at RepairPal Certified shops have the right tools and experience to solve any symptom.

How much does it cost to fix a 1999 Suzuki Swift cruise control isn't working?

Common Repairs

The total repair cost will vary based on the condition of your vehicle and the number of repairs needed to fix your symptom. Proper diagnosis will save you money by finding the exact repairs needed to fix your car right the first time.

When the throttle position sensor fails, the engine's computer tends to overcompensate with fuel, leading black exhaust coming from the tailpipe. There is a strong possibility of engine misfires, and the check engine light will come on.

Throttle position sensors can also develop "dead spots," or certain places along the throttle curve where it doesn't get a reading. When this happens, the above symptoms can occur but then stop when you further press or let off the gas pedal.

In the event that a wheel speed sensor fails, the ABS, traction control system (TCS) and manufacturer specific stability control system lights will illuminate, informing the driver that the systems are disabled. The vehicle will be more prone to tire slip, and normal driving patterns may need to be adjusted to correct for the loss of computer control. On older vehicle's, the speedometer can be affected, causing illumination of the check engine light as well.

What are the first steps to diagnose cruise control failure in a 1999 Suzuki Swift?

When diagnosing cruise control failure in a 1999 Suzuki Swift, it's essential to adopt a systematic diagnostic approach. Start by checking the fuses related to the cruise control system, as a blown fuse can often be the simplest explanation for the malfunction. Next, inspect the brake pedal and throttle body, as their proper functioning is crucial for cruise control operation. Utilizing a scanner can help identify any underlying issues, particularly with the speed sensor, which plays a vital role in the system's performance. Additionally, refer to the vehicle's manual to locate the fuse box in the engine bay and test the specific fuse for the cruise control using a multimeter or a visual inspection. Lastly, examine the brake switch, which has two sets of contacts; ensuring that these are functioning correctly is key, as one set disables the cruise control when the brake pedal is pressed. By following these steps, you can effectively diagnose and potentially resolve the cruise control issues in your Suzuki Swift.

What common issues cause cruise control failure in a 1999 Suzuki Swift?

When troubleshooting cruise control failure in a 1999 Suzuki Swift, it's crucial to understand the common problems that may be affecting the system. One of the primary culprits is the control module, which can fail and disrupt the entire cruise control functionality. Additionally, issues with sensors or switches, particularly the cruise control switch, can lead to malfunctions due to worn-out internal contacts that prevent proper communication with the control module. Electrical problems are also significant; check for issues with the wiring harness, connectors, and source voltage, as these can disable the cruise control system entirely. Furthermore, a blown fuse specific to the cruise control circuit can stop the system from working, while problems with the brake pedal position sensor or throttle body can also contribute to failure. Lastly, don't overlook the brake lights, as faulty lights can interfere with the cruise control operation since they are often linked to the same circuit. By systematically examining these components, you can effectively diagnose and address the cruise control issues in your Suzuki Swift.

How urgent is it to address the malfunctioning cruise control in a 1999 Suzuki Swift?

Addressing a malfunctioning cruise control in your 1999 Suzuki Swift is not just a matter of convenience; it is a critical safety concern that requires immediate attention. When cruise control fails, it can lead to erratic acceleration or inaccurate speed readings, which can compromise your control over the vehicle and increase the risk of accidents. Moreover, the discomfort of having to constantly press the gas pedal during long drives can lead to fatigue, making it harder to stay alert on the road. Ignoring these symptoms can exacerbate the problem, potentially leading to more extensive and costly repairs down the line. Therefore, if you notice any signs of malfunction, it is essential to diagnose and fix the issue promptly to ensure your vehicle operates safely and efficiently. Taking action now not only enhances your driving experience but also safeguards your well-being and that of others on the road.
