How will a mechanic replace my automatic shutdown relay?
If you decide to bring your vehicle to a mechanic, they will inspect under the hood and follow these steps to carry out an automatic shutdown relay replacement:
- Locate the Fuse Relay: Your owner’s manual provides precise information regarding the location of your fuse box and starter relay. Alternatively, your mechanic may already be familiar with this information based on your vehicle’s make and model, facilitating a quick identification of the fuse relay's position.
- Identify the Proper Relay: Since the relay panel typically houses multiple relays, determining the correct one for the automatic shutdown function is crucial. Your mechanic will carefully examine the relay panel to identify the specific relay associated with the automatic shutdown feature.
- Remove the Automatic Shutdown Relay: Once located, the automatic shutdown relay is removed cautiously to prevent any potential damage. Subsequently, your mechanic replaces the faulty automatic shutdown relay with a new one.
- Test Run: Following the replacement, your mechanic conducts a test run to ensure the proper functionality of all components and verify that your vehicle can be started without issues.
What happens if I don’t replace my automatic shutdown relay?
Not replacing your automatic shutdown relay can lead to your car becoming inoperable. Common problems of a neglected automatic shutdown relay include:
- Engine stalls
- Stagnant car due to dead alternator
- Car battery draining problems
- Engine failure
What is an automatic shutdown relay?
An automatic shutdown relay (ASD) serves as an electrical switch essential for powering your vehicle, particularly linked to the ignition system.
In the "OFF" position of the ignition switch, the automatic shutdown relay blocks power from reaching crucial components such as the fuel pump relay.
Upon switching the ignition to the "ON" position, power is directed to various electrical components, including the fuel pump and injectors, but solely during cranking. Once the ignition is released, power to these components is promptly cut off, safeguarding the fuel system.
When should I replace the automatic shutdown relay on my car?
You should replace the automatic shutdown relay on your car when you see clear deterioration, or when you experience the following symptoms:
- Stalling Vehicle: One of the most prevalent issues linked to a failing automatic shutdown relay is a stalling vehicle. Typically, the engine initiates but promptly stalls out. When the starter relay malfunctions, power fails to reach various circuits and components of the vehicle, indicating a potential need for replacement.
- Engine Doesn’t Turn On: Another indication of a deteriorating starter relay is an engine that refuses to start. This suggests that the necessary power to charge the battery isn’t reaching it, resulting in a stationary vehicle. Additionally, a dead battery could signal a need for attention to the main relay.
- Check Engine Light: An illuminated dashboard, particularly the check engine light, can serve as a straightforward indicator of automotive issues. If the ASD relay is malfunctioning, the check engine light may illuminate, signaling a potential problem requiring investigation.
- Lag While Accelerating: Lagging acceleration can also suggest a need for automatic shutdown relay replacement. If the ASD relay is damaged, voltage to other components may drop, resulting in lag. However, this symptom is less common.
How often should an automatic shutdown relay be replaced?
Automatic shutdown relays typically last up to 50,000 cycles, which corresponds to the lifespan of your vehicle. However, this duration can vary depending on factors such as driving frequency. If you drive more frequently than the average commuter, it's conceivable that your automatic shutdown relay may wear down faster than anticipated.
Can I replace my automatic shutdown relay myself?
Certainly, if you're comfortable with basic automotive tasks and have access to your owner’s manual, you can perform the replacement in your driveway. The manual should provide clear instructions on locating the automatic shutdown relay. However, if you're uncertain about its location or lack confidence in completing the replacement, it's advisable to seek assistance from a licensed mechanic for proper guidance.
FAQs
No, driving with a faulty automatic shutdown relay is not advisable. While your vehicle may start initially, it's likely to shut down shortly afterward due to battery draining issues and a lack of power. If you suspect a problem with your ASD relay, it's best to contact a professional mechanic for a thorough inspection and necessary repairs.
Various factors can contribute to the premature failure of a relay. Common issues include mechanical wear and contamination, both metallic and non-metallic. If your ASD relay fails before reaching the expected lifespan of your vehicle, mechanical wear over time is often the primary culprit.
ASD Relay Test Procedure
- Position Your Car: Ensure your car is in the "ON" position but not started, and remove the relay from its connector before testing.
- Resistance Check: Use an ohmmeter to measure the resistance between terminals 85 and 86 of the relay. The reading should be approximately 70-80 ohms.
- Connect Ohmmeter: Attach the ohmmeter across relay terminals 30 and 87A and check for continuity between them.
- Jumper Wire to Ground: Connect one end of a jumper wire (16 gauge or thicker) to relay terminal 85. During this step, ensure the ohmmeter does not indicate an open circuit. Then, connect the other end of the jumper wire to the ground side of a 12-volt power source.
- Jumper Wire to Power: Using another jumper wire, connect one end to the power side of the 12-volt power source. Ensure the ohmmeter does not make contact with terminals 85 and 86 during this test. Connect the other end to relay terminal 86 to activate the relay. If successful, the ohmmeter should indicate continuity between terminals 87 and 30, but not between 87A and 30.
- Disconnect: Finally, disconnect all wires. If the ASD relay requires replacement, the ohmmeter will not pass the continuity test.
