Land Cruiser URJ200 URJ202 GRJ200 VDJ200 - TIRE PRESSURE MONITORING
TIRE PRESSURE WARNING SYSTEM - TEST MODE PROCEDURE
| TEST MODE (SIGNAL CHECK MODE) PROCEDURE |
- HINT:
After the tire pressure warning ECU and receiver completes the signal check for each inspection item, the DTCs for systems that are determined to be normal will be cleared.
The DTCs for other inspection items may not be cleared when only a certain signal is inspected.
Turn the engine switch off.
Connect the GTS to the DLC3.
Turn the engine switch on (IG) and the GTS on.
Enter the following menus: Chassis / Tire Pressure Monitor / Utility / Signal Check.
- HINT:
- Every time the test mode (signal check mode) DTC clear conditions are satisfied, the tire pressure warning light illuminates for 1 second. Following this, the tire pressure warning light blinks at 0.125 second intervals.
| *a | 0.125 sec. |
| *b | ON |
| *c | OFF |
Press the tire pressure warning reset switch (C2198).
Wait for 1.5 minutes with the vehicle stopped, or drive the vehicle at a speed of 50 km/h (31 mph) or more for 1 minute (C2181 to C2185).
- HINT:
- The tire pressure warning valve and transmitters send signals to the tire pressure warning ECU and receiver once every 1.5 minutes while the vehicle is stopped and once every minute while driving.
Drive the vehicle at a speed of 20 km/h (12 mph) or more for 3 seconds or more to check the vehicle speed signal (C2191).
Perform the tire pressure warning antenna check (C2195).
- HINT:
- The conformity of the antenna connection and radio frequency is automatically detected.
During test mode (signal check mode), set the number of times required to turn the engine switch from off to on (IG) in order to return to normal mode to 2 times.
After entering test mode, turn the engine switch off and then on (IG) again.
Check that the tire pressure warning system test mode (signal check mode) DTCs are cleared.
| Test Mode (Signal Check Mode) DTC | Test Signal | Test Mode (Signal Check Mode) DTC Clear Condition |
| C2181 to C2185 | Transmitter Data | Data is received from the relevant transmitter which has a registered ID in the tire pressure warning ECU and receiver. |
| C2191 | Vehicle Speed Signal | Vehicle speed of 20 km/h (12 mph) or more is detected for 3 seconds or more. |
| C2195 | Open in tire pressure warning antenna Radio frequency mismatch | Continuity of the antenna terminal and conformity of the radio wave frequency are detected. |
| C2198 | Tire Pressure Warning Reset Switch Signal | A signal is received indicating that the tire pressure warning reset switch is pressed. |
Result
- HINT:
- After the signal check is completed, check for test mode (signal check mode) DTCs to confirm the system status.
| Condition | Procedure |
| Test mode (signal check mode) DTC is output | Repair the faulty part and enter Signal Check again |
| Test mode (signal check mode) DTCs are cleared | No problem |
End of test mode (signal check mode)
After completing the test mode (signal check mode), turn the engine switch off and disconnect the GTS.
