Test Mode Procedure
TEST MODE PROCEDURE1. ENTER TEST MODE
HINT:
- Operation of the tire pressure warning reset switch can be checked in TEST MODE.
- During TEST MODE, the system is not initialized by pushing the tire pressure warning reset switch. The circuit of the tire pressure warning reset switch can be inspected during this mode.
a. Make sure that the ignition switch is off.
b. Connect the hand-held tester to DLC3.
c. Turn the ignition switch to the ON position.
d. Select the TEST MODE on hand-held tester.
e. Perform tire pressure warning reset switch test.
1. Push the tire pressure warning reset switch.
2. Check the tire pressure warning indicator lamp.
2. PERFORM SIGNAL CHECK
HINT:
- When entering signal check, the tire pressure monitor ECU sets all the signal check DTCs first.
After completing signal check for each inspection item, the DTCs that are determined normal by the tire pressure monitor ECU will be erased.
The DTCs for other inspection items may not be erased when only a certain signal is inspected.
- When signal check returns back to normal mode, all the signal check DTCs will be erased.
a. Make sure that the ignition switch is off.
b. Connect the hand-held tester to DLC3.
c. Turn the ignition switch to the ON position.
d. Select the SIGNAL CHECK on hand-held tester.
e. Drive the vehicle at 12mph (20 km/h) or more for 10 seconds or more.
f. Loosen the valve core and rapidly reducing the pressure (20 kPa above/15 sec.).
HINT: The transmitter ID can be transmitted by rapidly reducing the tire air pressure.
g. Check that the tire pressure warning system test mode DTCs are erased.
h. Result
i. End of SIGNAL CHECK
After completing test mode (SIGNAL CHECK), turn the ignition switch OFF and disconnect the tester.
DTC of SIGNAL CHECK (TEST DIAGNOSIS) function:
C2181/81-C2191/91:
If a malfunction code is displayed during the test mode DTC check, check the circuit listed for that code. For details of each code, refer to the respective "DTC No." in the chart.
