what does code C1201 mean for my Toyota Highlander Third Generation (2014-2019)

Solution

1. Preparation

• Gather necessary tools and parts.
• Ensure the vehicle is parked on a level surface and the engine is turned off.
• Disconnect the negative battery terminal for safety.

2. Inspect ABS Fuse

• Locate the fuse box (consult owner's manual for location).
• Remove the ABS fuse and check for continuity using a multimeter.
  • If blown, replace with the same amperage fuse.

3. Check Wheel Speed Sensors

• Raise the vehicle using a jack and secure it with jack stands.
• Inspect each wheel speed sensor for dirt or debris; clean if necessary.
• Disconnect the sensor connectors and check for continuity with a multimeter.
  • Replace any faulty sensors as needed.

4. Inspect ABS Module

• Locate the ABS module, typically near the master cylinder.
• Check for any signs of physical damage or leaks from brake fluid.
• If the module is faulty, proceed with replacement.

5. Reconnect Battery and Clear Codes

• Reconnect the negative battery terminal.
• Use the OBD-II scanner to clear the C1201 code.
• Test drive the vehicle to ensure the ABS system functions correctly.
