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).

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.

 .

Are there any tires whose pressure is “64 psi” or more?

YES

>> Adjust tire pressure to specified value.

NO

>> GO TO 2.

2. 

VEHICLE DRIVING

1.

Perform ID registration of all transmitters.

2.

Drive at a speed of 40 km/h (25 MPH) or more for several minutes without stopping. 
Check all tire pressures with CONSULT-II “DATA MONITOR” within 15 minutes after vehicle speed
becomes 17 km/h (11 MPH).
