EASY FILL TIRE ALERT DOES NOT ACTIVATE
EASY FILL TIRE ALERT DOES NOT ACTIVATE
DescriptionINFOID:0000000012432461
The easy fill tire alert does not function while inflating a tire when the select lever position is in P-range with the
ignition switch ON.
NOTE:
• After starting to inflate the tire, it takes a few seconds for the easy fill tire alert to function.
• If there is no response for approximately 15 seconds or mo re after inflating the tires, cancel the use of the
easy fill tire alert function or move the vehicle approximately 1 m (3.2 ft) backward or forward to try again.
The air filler pressure may be weak or out of service area.
• For easy fill tire alert, Refer to WT-8, "
TIRE PRESSURE MONITORING SYST EM : Easy Fill Tire Alert Func-
tion".
Diagnosis ProcedureINFOID:0000000012432462
1. LOCATION CHANGE
Move the vehicle to other area and repeat the procedure of the easy fill tire alert function. Refer to WT-8,
"TIRE PRESSURE MONITORING SYSTEM : Easy Fill Tire Alert Function".
Is the function normal?
YES >> Normal (the easy fill tire alert may not operate, depending on reception condition.)
NO >> GO TO 2.
2.PERFORM BCM SELF-DIAGNOSIS
With CONSULT
Perform self-diagnosis for “AIR PRESSURE MONITOR”.
Is any DTC detected?
YES >> Perform trouble diagnosis for detected DTC. Refer to BCS-50, "DTCIndex" (with Intelligent Key
system) or BCS-115, "
DTCIndex" (without Intelligent Key system).
NO >> GO TO 3.
3.CHECK HAZARD WARNING LAMP OPERATION
Check hazard warning lamp operation with hazard switch.
Does the hazard warning lamp blink?
YES >> GO TO 4.
NO >> Perform trouble diagnosis for the hazard warning lamp. Refer to EXL-85, "
Diagnosis Procedure" .
4.PERFORM TCM SELF-DIAGNOSIS
With CONSULT
Perform self-diagnosis for “TRANSMISSION”.
Is any DTC detected?
YES >> Check malfunctioning circuit. Refer to TM-110, "DTC Index".
NO >> GO TO 5.
5.CHECK HORN OPERATION
Check horn operation. Refer to HRN-3, "
Wiring Diagram".
Is the operation normal?
YES >> GO TO 6.
NO >> Repair or replace error-detected parts.
6.PERFORM BCM SELF-DIAGNOSIS
With CONSULT
1. Drive for 10 minutes at a speed of 40 km/h (25 MPH) or more.
CAUTION:
