MALFUNCTION CODE NO. 25, 26, 27, 28

1.CHECK LOW TIRE PRESSURE WARNING CONTROL UNIT AND RECEIVER CONNECTOR
1. Turn ignition switch OFF, disconnect low tire pressure warning control unit harness connector and receiver harness connector, and check terminal for deformation, disconnection, looseness, and so on. If there is a malfunction, repair or replace the terminal.
2. Reconnect harness connector securely, and perform self-diagnosis.
Does "SELF-DIAG RESULTS" display as normal without any warning lamp?
YES >> Connector terminal connection is loose, damaged, open, or shorted.
NO >> GO TO 2.

2.CHECK TIRE PRESSURE RECEIVER POWER SUPPLY AND GROUND CIRCUIT
1. Turn ignition switch OFF, and disconnect tire pressure receiver harness connector E74, E75, B115, B482.





2. Check continuity between tire pressure receiver harness connector E74, E75, B115, B482 and ground.
Terminal 4 - Ground: Continuity should exist.





3. Turn ignition switch ON, and then check voltage between tire pressure receiver harness connector E74, E75, B115, B482 and ground.
1 - Ground: Battery voltage (Approx.12 V)
OK or NG
OK >> GO TO 3.
NG >> GO TO 4.

3.CHANGE THE TIRE PRESSURE RECEIVER POSITION (EXAMPLE OF FRONT LH SIDE)
1. Replace right from left for front and rear receivers.
2. Perform self-diagnosis.
Is the initial indication of self-diagnosis displayed?
YES >> GO TO 4
NO >> Replace tire pressure receiver front RH when indicating RH tire pressure receiver malfunction.

4.CHECK RECEIVER HARNESS (EXAMPLE OF FRONT LH SIDE)





1. Turn ignition switch OFF, disconnect low tire pressure warning control unit harness connector M19 (A) and receiver harness connector E74 (B).
2. Check continuity between low tire pressure warning control unit harness connector M19 (A) and receiver harness connector E74 (B).
Terminal 27 - 2: Continuity should exist.
Terminal 11 - 3: Continuity should exist.
OK or NG
OK >> Replace low tire pressure warning control unit.
NG >> Harness between Low tire warning control unit and receiver open or shorted. Repair or replace harness.
