TROUBLE DIAGNOSIS FOR SELF-DIAGNOSTIC ITEMS
Revision: 2006 January2006 M35/M45
2. REPLACE TIRE PRESSURE TRANSMITTER
1. Check low tire pressure warning condition again, and replace malfunctioning tire pressure transmitter.
2. Perform ID registration of all transmitter.
Can ID registration of all tire pressure transmitters be completed?
YES >> GO TO 3.
NO >> GO TO the inspection 1. Refer to WT-30, "
Inspection 1: Transmitter no Data" .
3. VEHICLE DRIVING
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” within 5 minutes.
Does
“DATA MONITOR” display tire pressure as normal without any warning lamp?
YES >> INSPECTION END
NO >> Replace malfunctioning transmitter, and perform “Step 3” again.
Inspection 7: Vehicle Speed SignalNES000KG
MALFUNCTION CODE NO. 52
1. CHECK SELF-DIAGNOSIS RESULTS
1. Turn ignition switch OFF.
2. Connect CONSULT-II and CONSULT-II CONVERTER to data link connector.
3. Turn ignition switch ON.
4. Touch “START (NISSAN BASED VHCL)” “AIR PRESSURE MONITOR”.
–If “AIR PRESSURE MONITOR” is not displayed, print the “SELECT SYSTEM” screen. Then refer to LAN-
7, "Precautions When Using CONSULT-II" .
NOTE:
Just after starting engine, or turning ignition switch ON, it may not be displayed even if “START (NISSAN
BASED VHCL)” is touched. In this case, reconnect CONSULT-II and CONSULT-II CONVERTER.
5. Touch “SELF-DIAG RESULTS” on “SELECT DIAG MODE” screen.
6. Check display contents in self-diagnostic results.
Is
“CAN COMM CIRCUIT” displayed in the self-diagnosis display items?
YES >> Malfunction in CAN communication system. GO TO LAN-7, "Precautions When Using CONSULT-
II" .
NO >> No malfunction. Check combination meter refer to DI-18, "
Trouble Diagnosis" .
Inspection 8: CAN Communication System MalfunctionNES000KS
1. CHECK LOW TIRE PRESSURE WARNING CONTROL UNIT CONNECTOR
1. Turn ignition switch OFF, disconnect low tire pressure warning control unit harness connector, and check
terminal for deformation, disconnection, looseness, etc.
2. Reconnect harness connector securely, and perform CONSULT-II self-diagnosis.
Is above displayed on self-diagnosis display?
YES >> If “CAN COMM CIRCUIT [U1000]” is displayed, print out self-diagnosis. And then, go to LAN-7,
"Precautions When Using CONSULT-II" .
NO >> Connector terminal connection is loose, damaged, open, or shorted. Repair or replace the termi-
nal.
