NOTE:
Before performing the self-diagnosis, be sure to register the ID or else the actual malfunction location may be different from that dis-
played on CONSULT-III.

Self-Diagnosis (Without CONSULT-III)

INFOID:0000000004212519

SELF DIAGNOSTIC PROCEDURE (WITHOUT CONSULT-III)

1. Turn ignition switch ON.

2. Ground the tire pressure warning check connector to initiate self diagnosis.

3. Compare the flashing pattern with the flash code chart below.

NOTE:

The system is normal when the low tire pressure warning lamp flashes 5 times and continues repeating. Self-

diagnosis results are erased automatically by turning the ignition switch “OFF”.

DIAGNOSTIC PROCEDURE

1.

SELF-DIAGNOSTIC RESULT CHECK

Using CONSULT-III, check display contents of BCM in SELF-DIAGNOSIS.
Is "CAN COMM CIRCUIT" displayed in the self-diagnosis display items?

YES

>>  Malfunction in CAN communication system.   Refer to 

LAN-27, "CAN System Specification

Chart"

.

NO

>> GO TO 2

2.

CHECK COMBINATION METER

Check combination meter operation.  Refer to 

MWI-35, "CONSULT-III Function (METER/M&A)"

.

Is the inspection result normal?

YES

>> GO TO 3

NO

>> Replace combination meter. Refer to 

MWI-135, "Removal and Installation"

.

3.

CHECK LOW TIRE PRESSURE WARNING LAMP

Disconnect BCM harness connector. 
Does the low tire pressure warning lamp activate?

YES

>> Replace BCM. Refer to 

BCS-87, "Removal and Installation"

.

NO

>> Check combination meter operation.
