Solution

1. Preparation

Tools Required: OBD-II scanner, socket set, multimeter, fluid pump, transmission fluid.
Ensure the vehicle is parked on a level surface.
Disconnect the battery negative terminal to prevent electrical shorts.

2. Inspect and Replace Transmission Fluid

Sub-steps:
1. Locate the transmission dipstick and remove it.
2. Check the fluid level; add fluid if low using the appropriate type (Toyota WS fluid).
3. If the fluid is dark or has a burnt smell, a fluid change is necessary.
4. Remove the drain plug from the transmission pan and allow old fluid to drain completely.
5. Replace the drain plug and refill with new transmission fluid using a fluid pump.

3. Check and Replace Brake Pedal Switch

Sub-steps:
1. Locate the brake pedal switch above the brake pedal.
2. Disconnect the wiring harness from the switch.
3. Test the switch with a multimeter; it should show continuity when the pedal is pressed.
4. If faulty, remove the switch and replace it with a new one.
5. Reconnect the wiring harness and ensure the switch operates correctly.

4. Inspect and Adjust Transmission Linkage

Sub-steps:
1. Locate the transmission linkage under the vehicle.
2. Inspect for any signs of wear, damage, or disconnection.
3. If misaligned, adjust the linkage according to the service manual specifications.
4. Tighten any loose bolts and ensure all connections are secure.

5. Test Transmission Solenoids

Sub-steps:
1. Locate the transmission solenoid assembly.
2. Disconnect the electrical connector from the solenoids.
3. Use a multimeter to check for resistance; refer to specifications in the service manual.
4. Replace any solenoids that do not meet specifications.
