How to Perform Trouble Diagnosis for Quick and Accurate RepairNES000GY
INTRODUCTION
Before troubleshooting, verify customer complaints.
If a vehicle malfunction is difficult to reproduce, harnesses, harness connectors or terminals may be mal-
functioning. Hold and shake these parts to make sure they are securely connected.
When using a circuit tester to measure voltage or resistance of each circuit, be careful not to damage or
deform connector terminals.

Does warning lamp activate?
YES >> GO TO 3.
NO >> Check fuse and combination meter.
3. CHECK CONNECTOR
1. Disconnect BCM harness connectors M3 and M4.
2. Check terminals for damage or loose connection.
OK or NG
OK >> GO TO 4.
NG >> Repair or replace damaged parts.
4. CHECK TRANSMITTER TOOL
Check activation tool battery.
OK or NG
OK >> Perform self-diagnosis.
NG >> Replace activation tool battery.

TROUBLE DIAGNOSIS FOR SELF-DIAGNOSTIC ITEMS
Revision: 2006 December 2006 FX35/FX45
TROUBLE DIAGNOSIS FOR SELF-DIAGNOSTIC ITEMSPFP:00000
Inspection 1: Transmitter or Control Unit (BCM)NES000H1
MALFUNCTION CODE NO. 21, 22, 23 OR 24
1. CHECK CONTROL UNIT
Drive for several minutes. Check all tire pressures with CONSULT-II “DATA MONITOR ITEM”.
Are all tire pressures displayed 0 kPa?
YES >> GO TO 2.
NO >> GO TO 3.
2. CHECK REMOTE KEYLESS ENTRY RECEIVER CONNECTOR
1. Disconnect remote keyless entry receiver harness connector M98.
2. Check terminals for damage or loose connection.
3. Reconnect harness connector.
OK or NG
OK >> Replace BCM refer to BCS-15, "Removal and Installation of BCM" , then GO TO 3.
NG >> Repair or replace remote keyless entry receiver harness connector.
3. ID REGISTRATION
Perform ID registration of all transmitters.
Is there any tire that ID can not be registered to?
YES >> Replace transmitter of the tire, then GO TO 5.
NO >> GO TO 4.
4. VEHICLE DRIVING
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 ITEM” within 15 minutes after vehicle speed
becomes 17 km/h (11 MPH).
Does
“DATA MONITOR ITEM” display tire pressure as normal without any warning lamp?
YES >> INSPECTION END
NO >> GO TO 5.
5. ID REGISTRATION AND VEHICLE DRIVING
1. Perform ID registration of all transmitters.
2. Drive at a speed of 40 km/h (25 MPH) or more for 3 minutes, and then drive the vehicle at any speed for 10 minutes. Then check all tire pressures with CONSULT-II “DATA MONITOR ITEM” within 5 minutes.
Does
“DATA MONITOR ITEM” display tire pressure as normal without any warning lamp?
YES >> INSPECTION END
NO >> GO TO the inspection applicable to DTC.
Inspection 2: Transmitter - 1NES000H2
MALFUNCTION CODE NO. 31, 32, 33, 34, 41, 42, 43, 44, 45, 46, 47 OR 48
