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 con-
nector E74, E75, B115, B482 and ground.
3. Turn ignition switch ON, and then check voltage between tire
pressure receiver harness connector E74, E75, B115, B482 and
ground.
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.Terminal 4 – Ground : Continuity should exist.
