After replacing the battery, the central control may malfunction due to disconnected wiring. Here are the specific details: 1. Cause of malfunction: When replacing the battery, to avoid short-circuiting the positive and negative terminals, the battery wiring may be bent and separated as much as possible. This can sometimes lead to disconnection, especially if an additional anti-theft alarm was installed after purchasing the car, which requires cutting the original power supply wiring for connection, compromising the wiring's sealing. Over time, exposure to air can cause oxidation. 2. Solution: Check if the wiring is properly connected and if there are any breaks, particularly in manually connected areas.

What Causes the Squeaking Sound When Driving on Bumpy Roads?

Regarding the causes of abnormal noises when driving on bumpy roads: 1. Lower control arm issue: The lower control arm supports the tires and has two rubber bushings. Prolonged driving and steering wheel operation can cause wear on the small ball joints and bushings, leading to excessive gaps and abnormal noises when driving on uneven roads. Replacing the control arm can directly resolve the noise issue. 2. Stabilizer bar link issue: The stabilizer bar link, commonly known as a small tie rod, helps maintain vehicle stability during driving. For example, when the left and right wheels are at different heights, the stabilizer bar generates anti-roll resistance to prevent body roll and twisting of the bar. Prolonged driving can cause excessive wear inside the small ball joints, resulting in excessive gaps and abnormal noises.

Is the touch-up pen useful?

The touch-up pen is useful. It can cover up some minor and shallow scratches on the surface, making them less noticeable. The effect is quite good, although it cannot achieve the same result as the original car paint, it is much better than leaving the scratches untreated. For deeper or larger scratches, or those that expose the primer, the touch-up pen cannot effectively repair them. There may be color discrepancies and a lack of gloss, resulting in less than ideal results. For the proper use of a touch-up pen, the professional method is to cover areas that do not need to be painted with tape, select the appropriate color and model of the touch-up pen that matches the car paint, shake the pen well to mix the paint inside, and then apply it evenly and smoothly to the minor scratches or imperfections on the car body. Once the paint dries, it can repair, conceal, and fill in the scratches, and it also provides some rust-proofing function.

What is the 0-100km/h acceleration time of the Ford Equator?

Ford Equator's 0-100km/h acceleration time is 12.6 seconds. Equipped with a 1.5T+CVT powertrain, the Ford Equator pursues a comfortable and smooth driving experience. During the 0-100km/h acceleration test, the Equator maintains a quite stable posture at launch without noticeable wheel slip. The maximum engine speed at launch can be maintained around 2500rpm, delivering continuous linear acceleration. Through multiple acceleration tests, the Equator's acceleration time remains around 12.6 seconds. The relatively smooth speed curve indicates that the CVT transmission makes the entire acceleration process quite smooth. Judging from the G-value, the maximum acceleration at launch only reaches 0.5g, meaning the acceleration doesn't deliver strong push-back sensation. The driving experience is rather comfortable, which aligns with the Equator's power characteristics.
