The method to clear the idle stop malfunction in the Highlander is: 1. Check whether the throttle is blocked and clean the throttle; 2. It is necessary to check the throttle circuit to see if it is short-circuited or open-circuited, and reset it after decoding with an instrument. The Highlander is a large-size SUV produced by Toyota. Taking the 2021 Highlander as an example, its body dimensions are: length 4890mm, width 1925mm, height 1720mm, and the wheelbase is 2790mm. The 2021 Highlander is equipped with a 2.0T turbocharged engine, with a maximum power of 162kW and a maximum torque of 350Nm, matched with a 6-speed automatic manual transmission, and its front suspension type is MacPherson independent suspension.
I've been in the auto repair industry for many years and have encountered numerous cases of Highlander idle stop malfunctions. The most common troubleshooting method is first connecting a diagnostic tool to the OBD port to read the fault codes. When handling these cases, I typically check whether it's caused by low battery voltage or dirty sensors, as Toyota's system is quite sensitive. If the voltage is below standard values, I either recharge the battery or replace it with a new one; if the sensors are dirty, I clean them with compressed air. After clearing the fault codes, I recommend taking a short test drive to see if the system recovers. If the problem persists, replacement of related components may be necessary, such as the throttle position sensor or ECU module. This job requires experience - don't mess around carelessly to avoid damaging other circuits. I suggest regularly checking the idle stop function status during routine maintenance to prevent many issues. In short, safety comes first - never ignore warning lights while driving.
