Test Mode Procedure

TIRE AND WHEEL: TIRE PRESSURE WARNING SYSTEM: TEST MODE PROCEDURE

1. PERFORM SIGNAL CHECK

HINT
* When entering signal check mode (test mode), the tire pressure warning ECU and receiver sets all the signal check DTCs first.
* After completing the signal check for each inspection item, the DTCs that are determined to be normal by the tire pressure warning ECU and receiver will be cleared.
* The DTCs for other inspection items may not be cleared when only a certain signal is inspected.
* When signal check returns to normal mode, all the signal check DTCs will be erased.
(a) Turn the ignition switch OFF.

(b) Connect the Techstream to the DLC3.

(c) Turn the ignition switch ON and the Techstream on.

(d) Enter the following menus: Chassis / Tire Pressure Monitor / Utility / Signal Check.

HINT
Every time the test mode DTC erasure conditions are satisfied, the tire pressure warning light comes on for 1 second. Then, the tire pressure warning light blinks at 0.125 second intervals.





(e) Drive the vehicle at 20 km/h (12 mph) or more for 3 seconds or more to check the vehicle speed signal (C2191/91).

(f) Loosen the valve core and rapidly reduce the pressure (at least 40 kPa (0.4 kgf/cm2, 5.8 psi) within 30 seconds or more) to check the transmitter data (C2181/81 to C2184/84).

HINT
The transmitter ID can be transmitted by rapidly reducing the tire pressure.

(g) Turn the select switch from off (MAIN) to on (2nd) and then to off (MAIN) to check the select switch signal (C2192/92).

(h) Check that the tire pressure warning system test mode DTCs are erased.





(i) Check the tire pressure warning reset switch.

(1) Press the tire pressure warning reset switch.

(2) Check the tire pressure warning light.





(j) Result

HINT
After the signal check is completed, check for a DTC and test mode DTC to confirm the system status.





(k) End of Signal Check

After completing test mode (Signal Check), turn the ignition switch OFF and disconnect the Techstream.

(l) DTC of Signal Check (Test Diagnosis)

(1) If a trouble code is displayed during the test mode DTC check, check the circuit indicated by the code. For details of each code, refer to the information below.
