Test Mode Procedure
TEST MODE PROCEDURE1. TEST MODE CHECK
HINT:
- When entering the TEST MODE, the tire pressure warning ECU sets all the test DTCs first. After completing the test mode for each inspection item, the DTCs that are determined normal by the tire pressure warning ECU will be erased. The DTCs for other inspection items may not be erased when only a certain signal is inspected.
- When the test mode returns back to the normal mode, all the test DTCs will be erased.
(a) Make sure that the power switch is OFF.
(b) Connect the intelligent tester (with CAN VIM) to the DLC3.
(c) Turn the power switch ON (IG).
(d) Select the TEST MODE on the intelligent tester.
(e) Confirm that the tire pressure warning light in the combination meter blinks at 0.125 second intervals.
2. PERFORM SIGNAL CHECK
HINT:
- When entering signal check, the tire pressure warning ECU sets all the signal check DTCs first. After completing signal check for each inspection item, the DTCs that are determined to be normal by the tire pressure warning 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 to normal mode, all the signal check DTCs will be erased.
(a) Make sure that the power switch is OFF.
(b) Connect the intelligent tester (with CAN VIM) to the DLC3.
(c) Turn the power switch ON (IG).
(d) Select the SIGNAL CHECK on the intelligent tester.
(e) Drive the vehicle at 12 mph (20 km/h) or more for 30 seconds or more.
(f) Loosen the valve core and rapidly reduce the pressure (above 40 kPa (0.4 kgf/cm2, 5.8 psi) / 30 seconds).
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 power switch OFF and disconnect the tester.
(j) DTC of SIGNAL CHECK (TEST DIAGNOSIS)
HINT: 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 relevant page listed under the respective "DTC No." in the chart.
