b. Shift the rotor one hole and secure rotor to wheel hub withnuts.
c. Measure runout.
d. Repeat steps a. to c. so that minimum runout position can be found.
4. If the runout is still out of speci®cation, turn rotor with on-car brake lathe (``MAD, DL-8700'', ``AMMCO 700 and 705'' or
equivalent).

Precautions
+Before connecting or disconnecting the ECM harness
connector, turn ignition switch OFF and disconnect nega-
tive battery terminal. Failure to do so may damage the ECM
because battery voltage is applied to ECM even if ignition
switch is turned off.
+When connecting ECM harness connector, tighten secur-
ing bolt until the gap between orange indicators disap-
pears.
: 3.0 - 5.0 Nzm (0.3 - 0.5 kg-m, 26 - 43 in-lb)
+When connecting or disconnecting pin connectors into or
from ECM, take care not to damage pin terminals (bend or
break).
Make sure that there are not any bends or breaks on ECM
pin terminal, when connecting pin connectors.
+Before replacing ECM, perform Terminals and Reference
Value inspection and make sure ECM functions properly.
Refer to EC-54.
+If MIL illuminates or blinks irregularly when engine is
running, water may have accumulated in fuel ®lter. Drain
water from fuel ®lter. If this does not correct the problem,
perform speci®ed trouble diagnostic procedures.
+After performing each TROUBLE DIAGNOSIS, perform
``OVERALL FUNCTION CHECK'' or ``DTC (Diagnostic
Trouble Code) CONFIRMATION PROCEDURE''.
The DTC should not be displayed in the ``DTC CONFIRMA-
TION PROCEDUREº if the repair is completed. The ``OVER-
ALL FUNCTION CHECK'' should be a good result if the
repair is completed.

DTC and MIL Detection Logic
When a malfunction is detected for the ®rst time, the malfunction (DTC) is stored in the ECM memory.
The MIL will light up each time the ECM detects malfunction. However, if the same malfunction is experienced
in two consecutive driving patterns and the engine is still running, the MIL will stay lit up. For diagnostic items
causing the MIL to light up, refer to ``DIAGNOSTIC TROUBLE CODE INDEX'', EC-1.
Diagnostic Trouble Code (DTC)
HOW TO READ DTC
The diagnostic trouble code can be read by the following methods.
1. The number of blinks of the malfunction indicator lamp in the Diagnostic Test Mode II (Self-Diagnostic
Results) Examples: 11, 13, 14, etc.
These DTCs are controlled by NISSAN.
2. CONSULT Examples: ``CAM POS SEN (PUMP)'', etc.
+Output of the trouble code means that the indicated circuit has a malfunction. However, in the Mode
II it does not indicate whether the malfunction is still occurring or occurred in the past and returned
to normal.
CONSULT can identify them. Therefore, using CONSULT (if available) is recommended.
HOW TO ERASE DTC
The diagnostic trouble code can be erased by the following methods.
Selecting ``ERASE'' in the ``SELF-DIAG RESULTS'' mode with CONSULT.
Changing the diagnostic test mode from Diagnostic Test Mode II to Mode I. (Refer to EC-32.)
+If the battery terminal is disconnected, the diagnostic trouble code will be lost within 24 hours.
+When you erase the DTC, using CONSULT is easier and quicker than switching the diagnostic test
modes.
HOW TO ERASE DTC (With CONSULT)
1. If the ignition switch stays ``ON'' after repair work, be sure to turn ignition switch ``OFF'' once. Wait at least
5 seconds and then turn it ``ON'' (Engine stopped) again.
2. Turn CONSULT ``ON'' and touch ``ENGINE''.
3. Touch ``SELF-DIAG RESULTS''.
4. Touch ``ERASE''. (The DTC in the ECM will be erased.)
HOW TO ERASE DTC (No Tools)
1. If the ignition switch stays ``ON'' after repair work, be sure to turn ignition switch ``OFF'' once. Wait at least
5 seconds and then turn it ``ON'' again.
2. Change the diagnostic test mode from Mode II to Mode I. (Refer to EC-32.)
SEF691S
ON BOARD DIAGNOSTIC SYSTEM DESCRIPTION
EC-30

Malfunction Indicator Lamp (MIL)
1. The malfunction indicator lamp will light up when the ignition
switch is turned ON without the engine running. This is a bulb
check.
+If the malfunction indicator lamp does not light up, refer to EL
section (``WARNING LAMPS AND CHIME'') or see EC-188.
2. When the engine is started, the malfunction indicator lamp
should go off.
If the lamp remains on, the on board diagnostic system has
detected an engine system malfunction.
If MIL illuminates or blinks irregularly after starting engine,
water may have accumulated in fuel ®lter. Drain water from
fuel ®lter.
ON BOARD DIAGNOSTIC SYSTEM FUNCTION
The on board diagnostic system has the following three functions.
1. BULB CHECK : This function checks the MIL bulb for damage (blown, open circuit,
etc.).
2. MALFUNCTION
WARNING: This is a usual driving condition. When a malfunction is detected, the
MIL will light up to inform the driver that a malfunction has been
detected.
3. SELF-DIAGNOSTIC
RESULTS: This function allows diagnostic trouble codes to be read.
Refer to ``HOW TO SWITCH DIAGNOSTIC TEST MODES'' on next page.
