DTC 95

TIRE AND WHEEL: TIRE PRESSURE WARNING SYSTEM: C2195/95: Multi-receiver Antenna Circuit (Test Mode DTC)

DTC C2195/95 - Multi-receiver Antenna Circuit (Test Mode DTC)

DESCRIPTION





WIRING DIAGRAM





INSPECTION PROCEDURE
NOTICE:
- When replacing the tire pressure warning ECU and receiver, read the IDs stored in the old ECU using the Techstream and write them down before removal.
- It is necessary to perform initialization Initialization after registration Registration of the transmitter IDs into the tire pressure warning ECU and receiver after the tire pressure warning ECU and receiver has been replaced.

PROCEDURE

1. IDENTIFY ANTENNA CORRESPONDING TO DTC
(a) Set the tire pressures to the appropriate specified values Component Tests and General Diagnostics.
(b) Turn the ignition switch OFF.
(c) Connect the Techstream to the DLC3.
(d) Turn the ignition switch ON and the Techstream on.
(e) Enter the following menus: Chassis / Tire Pressure Monitor / Data List.
(f) Check the values by referring to the table below.

Tire Pressure Monitor





HINT: *: It may take about 2 or 3 minutes until the values are displayed.
(g) Rapidly reduce the tire pressure for each wheel at least 40 kPa (0.4 kgf/cm2, 5.8 psi) within 30 seconds.
(h) Check the Data List.
NOTICE:
- It takes about 2 or 3 minutes to display the updated tire pressure data.
- When no "ID Tire Inflation Pressure" data has changed, reset the tire pressure to the appropriate specified value and rotate the tire 90 to 270°. Then rapidly release the tire pressure and recheck it.
- Record the "ID Tire Inflation Pressure" data transmitter ID that corresponds to each tire.
(i) After confirming that the "ID Tire Inflation Pressure" data for one tire (ID1 to ID4) has changed, repeat this procedure for each tire. Identify the antenna that corresponds to the DTC.

2. CHECK HARNESS AND CONNECTOR (ANTENNA - ECU AND RECEIVER)
(a) Disconnect the T9 and/or T10 ECU and receiver connector.
(b) Disconnect the T3, T4, T24 and/or T25 antenna connector.
(c) for Front LH:





(1) Measure the resistance according to the value(s) in the table below.
Standard resistance:





(d) for Front RH:





(1) Measure the resistance according to the value(s) in the table below.
Standard resistance:





(e) for Rear LH:





(1) Measure the resistance according to the value(s) in the table below.
Standard resistance:





(f) for Rear RH:





(1) Measure the resistance according to the value(s) in the table below.
Standard resistance:






NG -- REPAIR OR REPLACE HARNESS OR CONNECTOR
OK -- Continue to next step.
3. REPLACE TIRE PRESSURE WARNING ANTENNA
(a) Replace tire pressure warning antenna.
HINT:
- For the front side antennas, refer to the following procedures Removal.
- For the rear side antennas, refer to the following procedures Removal.

NEXT -- Continue to next step.
4. CHECK TEST MODE DTC
(a) Check test mode DTC Test Mode Procedure.
OK:
DTC is not output.
NG -- REPLACE TIRE PRESSURE WARNING ECU AND RECEIVER
OK -- END
