Diagnostic Trouble Code Chart
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.
CAUTION:
- When removing the part, turn the ignition switch OFF.
- When replacing steering angle, master cylinder pressure, yaw rate, deceleration sensors or/and the ECU, make sure to perform steering angle, master cylinder pressure, yaw rate, deceleration sensors zero point calibration. See step 6 under PRE-CHECK.
- Zero point calibration is needed not only when replacing the VSC related parts, but also when replacing or repairing the steering related parts and when changing the vehicle's straight-ahead condition for toe adjustment.
NOTE:
- Using SST 09843-18040, connect the terminals TC and CG. See Figure.
- If an abnormality is not found when inspecting parts, inspect the ECU.
- If a malfunction code is displayed during the DTC check, check the circuit listed for that code. For details of each code, see DTC test for respective "DTC No." in the DTC chart. See Fig 1.

- Drive the vehicle at 20 km/h (12 mph) for 30 seconds or more and check that the ABS warning light goes off.
- Clear the DTC. See step 1) e or f under PRE-CHECK.NOTE: There is a case that TOYOTA hand-held tester cannot be used when ABS warning light always ON.
There is a case that TOYOTA hand-held tester cannot be used when VSC TRAC warning light is always ON.Check DTC chart C1203/53 first, then trouble shoot according to the DTC chart of translate ECU if necessary.
For DTC chart of VSC system , see Fig 2.
For DTC chart of translate ECU (When DTC "C1203/53" of VSC system is output) , see Fig 3.
NOTE:
The BRAKE warning light does not turn on due to an error in VSC.
If it is on, check that the parking brake pedal is released, the brake fluid level is normal and no malfunction is identified in the fluid level warning switch system.
