WARNING: This page is about a different car, the 2002 Toyota Sequoia. However, it is still accessible from the selected car via links, so may be relevant.

1. Diagnose System :
1. Check the indicator.
  1. Turn the ignition switch ON.
  2. Check that the CRUISE main indicator light comes ON when the cruise control main switch is turned ON, and that the indicator light goes off when the main switch is turned OFF. See Figure.
2. Check the DTC, See Fig 3:
3. Output a DTC using diagnosis check wire:
  1. Turn the ignition switch ON.
  2. Using SST, connect terminals Tc and E1 of the DLC3. See Fig 4. SST 09843-18020.
  3. Read the DTC on the CRUISE MAIN indicator light. See Figure.
Using Toyota Hand-Held Tester :
1. Hook up the TOYOTA hand-held tester to the DLC3. See Fig 5.
2. Monitor the ECU data by following the prompts on the tester screen.
Clearing DTCs
1. The following actions will erase the DTCs and freeze-frame data.
  1. Operating the OBD II scan tool (complying with SAEJ1978) or TOYOTA hand-held tester to erase the codes. (See the OBD II scan tool's instruction book for operating instructions.)
  2. Disconnecting the battery terminals or EFI fuse.
2. After completing repairs, the DTC retained, in memory can be cleared by removing the ECU-B fuse for 10 seconds or more with the ignition switch OFF.
3. Check that the normal code is displayed after connecting the fuse.
Problem Symptom Confirmation (Road Test) .
1. Inspect the SET switch, see Figure:
  1. Push the main switch ON. See Figure.
  2. Drive at a desired speed (25 mph (40 km/h). or higher).
  3. Press the control switch to the SET/COAST. See Figure.
  4. After releasing the switch, check that the vehicle cruises at the desired speed.
2. Inspect the ACCEL switch, see Figure:
  1. Push the main switch ON. See Figure.
  2. Drive at a desired speed (25 mph (40 km/h) or higher).
  3. Check that the vehicle speed increases while the control switch is turned to RES/ACC, seeFigure and that the vehicle cruises at the set speed when the switch is released.
  4. Momentarily press the control switch upward for RES/ACC, seeFigure and then immediately release it. Check that the vehicle speed increases by about 1.5 Km/h (Tap-up function).
3. Inspect the COAST switch:
  1. Push the main switch ON. See Figure.
  2. Drive at a desired speed 25 mph (40 km/h) or higher.
  3. Check that the vehicle speed decreases while the control switch is turned to SET/COAST, and the vehicle cruises at the set speed when the switch is released. See Figure.
  4. Momentarily press the control switch is turned to SET/COAST, and then immediately release it. Check that the vehicle speed decreases by about 1.5 km/h (Tap-down function).
4. Inspect the CANCEL switch, see Figure:
  1. Push the main switch ON. See Figure.
  2. Drive at a desired speed 25 mph (40 km/h) or higher.
  3. When operating one of the followings, check that the cruise control system is cancelled and that the normal driving mode is reset.
    . Depress the brake pedal.
    
    . Shift to except D position (A/T).
    
    . Push the main switch OFF.
    
    . Pull the cruise control switch to CANCEL. See Figure.
5. Inspect the RESUME switch, see Figure:
  1. Push the main switch ON. See Figure.
  2. Drive at a desired speed 25 mph (40 km/h) or higher.
  3. When operating one of the followings, check that the cruise control system is cancelled and that the normal driving mode is reset:
    . Depress the brake pedal.
    
    . Shift to except "D" position (A/T).
    
    . Pull the cruise control switch to CANCEL. See Figure.
  4. After the control switch is turned to RES/ACC, see Figure, at the driving speed of more than 40 km/h (25 mph), check that the vehicle restores the speed prior to the cancellation.
Input Signal Check (Using TOYOTA Hand-Held Tester) .
1. Connect the TOYOTA hand-held tester to DLC3. See Fig 5.
2. Check the control switch (MAIN, CANCEL, SET/COAST, RES/ACC). See Figure, Figure, Figure and Figure .

• Brakes feel soft, pull hard to one side, or make grinding noises.
• The engine overheats, stalls repeatedly, or misfires under load.
• You are missing required tools, torque specs, or safe lifting equipment.
• You are not confident in the next step or safety outcome.
