NOTE:
If more than one wheel transmitter is NOT activated, the warning lamp blinking patterns for those wheels will combine. (Example: one
blink/OFF/three blinks = Tire pressure transmitter rear LH and rear RH are not activated.)Low tire pres-

TROUBLE DIAGNOSIS FOR SYSTEM
Revision: 2007 April2007 M35/M45
Control Unit (EEPROM) MalfunctionNES000KT
MALFUNCTION CODE NO. 54
1. CHECK SELF-DIAGNOSIS RESULTS
1. Turn ignition switch “ON”. (Do not start engine.)
2. Select “SELF-DIAG RESULT” mode for “AIR PRESSURE MONITOR” with CONSULT-II.
3. Touch “ERASE”.
4. Turn ignition switch OFF, and wait at least 10 seconds.
5. Start engine.
6. Perform the self-diagnosis again.
Is the
“CONTROL UNIT (EEPROM) [C1754]” displayed?
YES >> Replace low tire pressure warning control unit. Refer to WT-40, "Low Tire Pressure Warning Con-
trol Unit" .
NO >>INSPECTION END
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-
50, "CAN System Specification Chart" .
Replace low tire pressure warning control unit if “CONTROL UNIT [CAN] [U1010]” is displayed.
NO >> Connector terminal connection is loose, damaged, open, or shorted. Repair or replace the termi-
nal.

CONSULT-II Functions (IPDM E/R)NKS003WM
CONSULT-II can display each diagnostic item using the diagnostic test mode shown following.
CONSULT-II BASIC OPERATION
Refer to GI-38, "CONSULT-II Start Procedure" .
DATA MONITOR
Operation Procedure
1. Touch “DATA MONITOR” on “SELECT DIAG MODE ” screen.
2. Touch “ALL SIGNALS”, “MAIN SIGNALS” or “SELECTION FROM MENU” on the “SELECT MONITOR
ITEM” screen.
3. When “SELECTION FROM MENU” is selected, touch individual items to be monitored. In “ALL SIG-
NALS”, all items are monitored. In “MAIN SIGNALS”, predetermined items are monitored.

All Signals, Main Signals, Selection From Menu
NOTE:
Perform monitoring of IPDM E/R data with the ignition switch ON. When the ignition switch is at ACC, the dis-
play may not be correct.
ACTIVE TEST
Operation Procedure
1. Touch “ACTIVE TEST” on “SELECT DIAG MODE” screen.
2. Touch “FRONT WIPER” on “SELECT TEST ITEM” screen.
3. Touch item to be tested, and check operation.
4. Touch “OFF” while testing to stop the operation.
Diagnosis Mode Description
SELF−DIAG RESULTS Refer to PG-20, "
SELF-DIAG RESULTS" .
DATA MONITOR The input/output data of IPDM E/R is displayed in real time.
CAN DIAG SUPPORT MNTR The result of transmit/receive diagnosis of CAN communication can be read.
ACTIVE TEST IPDM E/R sends a drive signal to electronic components to check their operation.
ALL SIGNALS Monitors all items.

7. CHECK IPDM E/R
With CONSULT-II
1. Connect IPDM E/R connector and front wiper motor connector.
2. Install front wiper reverse relay.
3. Select “IPDM E/R” on CONSULT-II. Select “ACTIVE TEST” on “SELECT DIAG MODE” screen.
4. Select “FRONT WIPER” on “SELECT TEST ITEM” screen.
5. Touch “LO” or “HI” screen.
6. Check voltage between IPDM E/R harness connector and
ground while front wiper (HI, LO) is operating.
Without CONSULT-II
1. Connect IPDM E/R connector and front wiper motor connector.
2. Install front wiper reverse relay.
3. Start up auto active test. Refer to PG-23, "
Auto Active Test" .
4. Check voltage between IPDM E/R harness connector and ground while front wiper (HI, LO) is operating.
OK or NG
OK >> Replace front wiper motor. Refer to WW-44, "Disassembly and Assembly of Front Wiper Drive
Assembly" .
NG >> Replace IPDM E/R. Refer to PG-31, "
Removal and Installation of IPDM E/R" .
Front Wiper Does Not Return to Stop Position (After Front Wiper Operate for 10
Seconds, They Stop for 20 Seconds, and After Repeating the Operations Five
Times, They Become Inoperative)
NKS003WO
CAUTION:
When auto stop signal has not varied for 10 seconds or longer while IPDM E/R is operating front
wipers, IPDM E/R considers that front wipers are locked, and stops wiper output. That causes this
symptom.
This status can be checked by “DATA MONITOR” of “IPDM E/R” on which “WIPER PROTECTION”
item shows “BLOCK”.
