1.CHECK BCM
Drive for several minutes. Check all tire pressures with CONSULT-II.
Are all tire pressures displayed as 0 kPa?
YES >> GO TO 2.
NO >> GO TO 3.
2.CHECK REMOTE KEYLESS ENTRY RECEIVER CONNECTOR
Check remote keyless entry receiver connector for damage or loose connections.
OK or NG
OK >> Replace BCM, then GO TO 3. Refer to BCS-24, "BCM".
