What Is The C1128-92 Hill Hold And How To Fix C1128-92 Hill Hold Disable Issue With Toyota Glanza 2022 Model
The C1128-92 hill hold disable issue is an error code that indicates a malfunction in the hill hold function of the Toyota Glanza 2022 model. The hill hold function is a feature that allows the car to maintain its position on a slope when the brake pedal is released, without rolling backwards or forwards. This function is activated automatically when the car detects a slope of more than 5 degrees and the brake pedal is pressed. The function is deactivated when the accelerator pedal is pressed or the car speed exceeds 3 km/h.
The C1128-92 hill hold disable issue occurs when the car’s electronic system fails to activate or deactivate the hill hold function properly, resulting in a loss of control or stability on a slope. The car’s dashboard will display three warning messages: service engine, hill hold disabled, and ESP disabled. The car may also fail to start or stall on a slope.

What Causes the C1128-92 Hill Hold Disable Issue?
The C1128-92 hill hold disable issue can be caused by various factors, such as:
1. A low or faulty battery
The hill hold function relies on the car’s battery to provide sufficient voltage and current to the electronic system. If the battery is low, old, damaged, or has an internal circuit break, it may cause a voltage drop or fluctuation that affects the hill hold function. The car may also have difficulty starting or cranking due to a weak battery.
2. A faulty brake system
The hill hold function also depends on the brake system to function properly. If the brake fluid is low, leaking, or contaminated, or if the brake lines are damaged or clogged, it may impair the brake pressure or performance. The car may also have reduced braking efficiency or responsiveness due to a faulty brake system.
3. A faulty throttle body or sensor
The hill hold function is controlled by the car’s electronic system, which receives signals from various sensors and actuators. One of these sensors is the throttle position sensor, which monitors the position of the throttle body. The throttle body is a valve that regulates the air intake into the engine. If the throttle body or sensor is dirty, damaged, or misaligned, it may send incorrect or inconsistent signals to the electronic system, causing the hill hold function to malfunction. The car may also have poor acceleration or idling due to a faulty throttle body or sensor.
4. A faulty electronic control module (ECM) or wiring
The ECM is the brain of the car’s electronic system, which processes the signals from the sensors and actuators and controls the hill hold function. If the ECM is damaged, corrupted, or has a software glitch, it may fail to communicate or coordinate with the hill hold function. The wiring that connects the ECM to the other components may also be damaged, loose, or shorted, causing a disruption or interference in the signal transmission. The car may also have other electrical or electronic issues due to a faulty ECM or wiring.
How to Diagnose the C1128-92 Hill Hold Disable Issue?
To diagnose the C1128-92 hill hold disable issue, you will need a diagnostic tool that can read and clear the error codes from the car’s electronic system. You can use a professional scanner or a simple adapter that connects to your smartphone via Bluetooth. Here are the steps to diagnose the C1128-92 hill hold disable issue:
- Connect the diagnostic tool to the car’s OBD-II port, which is usually located under the dashboard near the driver’s side. Turn on the ignition and wait for the tool to establish a connection with the car’s electronic system.
- Scan the system for error codes and look for the C1128-92 code, which indicates a problem with the hill hold function. You may also find other related codes, such as C1122, P2119, or C1091, which indicate problems with the engine speed signal, the throttle actuator, or the ECM data, respectively.
- Clear the error codes and turn off the ignition. Disconnect the diagnostic tool and reconnect the battery’s negative terminal if you disconnected it earlier. Start the car and check if the warning messages on the dashboard are gone and if the hill hold function is working normally. If the issue is resolved, you have successfully fixed the C1128-92 hill hold disable issue. If the issue persists, you will need to perform further troubleshooting or seek professional help.
