Title: TIRE PRESSURE MONITORING: TIRE PRESSURE WARNING SYSTEM: TEST MODE PROCEDURE; 2019 - 2021 MY RAV4 RAV4 HV [11/2018 - 12/2021]

TEST MODE PROCEDURE

TEST MODE (SIGNAL CHECK MODE) PROCEDURE

HINT:

When entering test mode (signal check mode), the tire pressure warning ECU and receiver sets all the test mode (signal check mode) DTCs first.
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.
When test mode (signal check mode) returns to normal mode, all the test mode (signal check mode) DTCs will be cleared.
Operation of the tire pressure warning reset switch can be checked in test mode (signal check mode).
During test mode (signal check mode), the system will not be initialized by operating the steering pad switch assembly. The circuit of the tire pressure warning reset switch can be inspected during this mode.

(a) Turn the ignition switch off.

(b) Connect the Techstream to the DLC3.

(d) Turn the Techstream on.

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

Chassis > Tire Pressure Monitor > Utility

Tester Display
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

(f) Tire pressure warning reset switch check (DTC C2198).

(1) Select "Set Pressure" on the multi-information display and press the "OK" switch (steering pad switch assembly).

(g) Transmitter data reception check (DTCs C2181 to C2184 (C2185: w/ Full Size Spare Tire)).

(1) 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.

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.

(h) Check that the tire pressure warning system test mode (signal check mode) DTCs are cleared.

Transmitter Data

Data is received from the relevant transmitter which has a registered ID in the tire pressure warning ECU and receiver.

C2198

Tire Pressure Warning Reset Switch Signal

A signal is received indicating that the steering pad switch assembly is operated, "Set Pressure" on the multi-information display is selected and the "OK" switch (steering pad switch assembly) is pressed.

(i) 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) DTCs are output	Repair the faulty part and enter Signal Check again
Test mode (signal check mode) DTCs are cleared	No problem

(j) End of test mode (signal check mode)

(1) After completing test mode (signal check mode), turn the ignition switch off and disconnect the Techstream.

(k) Test mode (signal check mode) DTCs

(1) If a trouble code is displayed during the test mode (signal check mode) DTC check, check the diagnosis procedure listed for that code. For details of each code, refer to Link below.
