INSPECTION
1. Check valve seating condition at ordinary room tempera-
tures. It should seat tightly.
2. Check valve opening temperature and maximum valve lift.
Standard
Valve opening temperature Above 80 - 84ÉC (176 - 183ÉF)
Valve lift More than 10 mm/95ÉC
(0.39 in/203ÉF)
3. Then check if valve closes at 5ÉC (9ÉF) below valve opening
temperature.
Radiator
REMOVAL AND INSTALLATION
1. Remove under guard.
2. Drain engine coolant. Refer to MA section, ªChanging Engine
Coolantº.
3. Remove radiator shroud (lower).
4. Remove radiator shroud (upper).

HOW TO ERASE SELF-DIAGNOSIS RESULTS
With CONSULT-II
+ªSELF-DIAG [CURRENT]º
A current Self-diagnosis result is displayed on the CONSULT-II screen in real time. After the malfunc-
tion is repaired completely, no malfunction is detected on ªSELF-DIAG [CURRENT]º.
+ªSELF-DIAG [PAST]º
Return to the ªSELF-DIAG [CURRENT]º CONSULT-II screen
by pushing ªBACKº key of CONSULT-II and select ªSELF-
DIAG [CURRENT]º in ªSELECT DIAG MODEº. Touch
ªERASEº in ªSELF-DIAG [CURRENT]º mode.
NOTE:
If the memory of the malfunction in ªSELF-DIAG [PAST]º is
not erased, the User mode shows the system malfunction by
the operation of the warning lamp even if the malfunction is
repaired completely.
+ªTROUBLE DIAG RECORDº
The memory of ªTROUBLE DIAG RECORDº cannot be erased.
Without CONSULT-II
After a malfunction is repaired, return Diagnosis mode to User mode by switching the ignition ªOFFº for at
least 1 second, then back ªONº. At that time, the self-diagnostic result is cleared.
How to Perform Trouble Diagnoses for Quick
and Accurate Repair
A good understanding of the malfunction conditions can make troubleshooting faster and more accurate.
In general, each customer feels differently about a malfunction. It is important to fully understand the symp-
toms or conditions for a customer complaint.

DIGNOSTIC PROCEDURE 3 (without CONSULT-II)
Inspecting SRS malfunctioning parts by using ªAIR BAGº
warning lamp Ð Diagnosis mode
NOTE:
SRS will not enter Diagnosis mode if no malfunction is
detected in User mode.
1. Turn ignition switch ªONº.
2. After ªAIR BAGº warning lamp lights for 7 seconds, turn igni-
tion switch ªOFFº within 1 second.
3. Wait more than 3 seconds.
4. Repeat steps 1 to 3 twice (Perform 3 times in total).
5. Turn ignition switch ªONº.
SRS is now in Diagnosis mode.
6. ªAIR BAGº warning lamp operates in Diagnosis mode as fol-
lows:
NOTE:
If SRS does not enter Diagnosis mode even though malfunction
is detected in User mode, check the battery voltage.
If the battery voltage is less than 9V, charge the battery. Then
go to DIAGNOSTIC PROCEDURE 5, page RS-3029.
If the battery voltage is OK, replace the diagnosis sensor unit.
