2.

CUSTOMER PROBLEM ANALYSIS

(a) Interview the customer to confirm the trouble.

HINT:

It is important to collect as much specific information as possible from the customer to allow for a quick repair.

3.

ADJUST TIRE PRESSURE*

(a) Turn the ignition switch off.

(b) Connect the Techstream to the DLC3.

(c) Turn the ignition switch to ON.

(d) Turn the Techstream on.

(e) Enter the following menus: Chassis / Tire Pressure Monitor / Data List.

(f) Read the "ID Tire Inflation Pressure" values.

(g) Adjust all tire pressures to the standard values (See page 2016 - 2020 MY Sienna [12/2015 -        ]; TIRE PRESSURE MONITORING: TIRE PRESSURE WARNING SYSTEM: PRECAUTION ).

(h) Check the Data List (See page 2016 - 2020 MY Sienna [12/2015 -        ]; TIRE PRESSURE MONITORING: TIRE PRESSURE WARNING SYSTEM: DATA LIST / ACTIVE TEST ).

HINT:

  • It takes up to 5 or 6 minutes to display the updated tire pressure data.
  • If the problem is that the tire pressure decreases, wait until all of the tire pressure data is received by the ECU. If the data is received, the tire pressure warning light will turn off.
