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 while in this mode.
a. Make sure that the ignition switch is OFF.
b. Connect the intelligent tester (with CAN VIM) to the DLC3.
c. Turn the ignition switch ON.
d. Select the TEST MODE on the intelligent tester.
e. Perform tire pressure warning reset switch test.
1. Press the tire pressure warning reset switch.
2. Check the tire pressure warning indicator light.
OK:
2. PERFORM SIGNAL CHECK
HINT:
^ When entering the signal check, the tire pressure monitor ECU sets all the signal check DTCs first. After completing the 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 the 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 intelligent tester (with CAN VIM) to the DLC3.
c. Turn the ignition switch ON.
d. Select the SIGNAL CHECK on intelligent tester.
e. Drive the vehicle at 12 mph (20 km/h) or more for 10 seconds or more.
f. Loosen the valve core and rapidly reduce the pressure (40 kPa (0.4 kgf/cm2, 5.8 psi) above / 30 sec.).
HINT: The transmitter ID can be transmitted by rapidly reducing the tire pressure.
g. Check that the tire pressure warning system test mode DTCs are erased.
h. Result
HINT: After the signal check is completed, check for a DTC and signal check DTC to confirm the system status.
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: If a malfunction code is displayed during the test mode DTC check, check the circuit listed for that code.
