WARNING: This page is about a different car, the 2002 Toyota Tundra. 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, see Figure, comes ON when the cruise control main switch, see Figure, is turned ON, and that the indicator light goes off when the main switch is turned OFF.
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 CG of the DLC3. See Fig 4. SST 09843-18020.
  3. Read the DTC on the CRUISE MAIN indicator light. See Figure.
Monitor ECU Data By Using Toyota Hand-Held Tester:
1. Connect the TOYOTA hand-held tester to the DLC3. See Fig 5.
2. Monitor the ECM data by following the prompts on the tester screen.
Clearing DTCs:
1. Engine stopped.
2. Using SST, connect terminals Tc and E1 of the DLC3. SST 09843-18020
3. Pull the cruise control switch to CANCEL.
4. On the above mentioned condition, turn on the cruise control main switch 5 times within 3 seconds.
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. Push the control switch downward for the SET/COAST. See Figure.
  4. After releasing the switch, check that the vehicle cruises at the desired speed.
2. Inspect the ACC (Acceleration) 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, see Figure 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, 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 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 push the control switch downward for the 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.
    
    . Depress the clutch pedal (M/T).
    
    . Shift to except D position (A/T).
    
    . Push the main switch OFF.
    
    . Pull the cruise control switch for CANCEL. See Figure.
5. Inspect the RES (resume) switch:
  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 following, check that the cruise control system is cancelled and that the normal driving mode is reset:
    1. Depress the brake pedal.
    2. Depress the clutch pedal (M/T).
    3. Shift to except "D" position (A/T).
    4. Push the main switch OFF.
    5. 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 cancellation.
Input Signal Check:
NOTE:
- When 2 or more signals are input to the ECU, the lowest numbered code will be displayed first.
- For checks No. 1-3, Turn ignition switch ON.
- For check No. 4, Jack up the vehicle, Start the engine, Shift to D position.
1. Push the control switch to the SET/COAST or RES/ACC position and hold it down or up.
2. Push the main switch ON.
3. Check that the CRUISE main indicator light blinks twice or 3 times repeatedly after 3 seconds.
4. Turn the SET/COAST or RES/ACC switch OFF.
5. Operate each switch as listed. See Fig 7.
6. Read the blinking pattern of the CRUISE main indicator light.
7. After performing the check, turn the main switch OFF

When to See a Mechanic

Stop DIY work and contact a certified mechanic immediately if any of the following apply:

• You smell fuel, burning insulation, or see smoke.
• 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.
