WARNING!
(1) The service personnel must thoroughly review this manual, and especially its GROUP 52B – Supplemental Restraint
System (SRS) before beginning any service or maintenance of any component of the SRS or any SRS-related
component.
(2) When removing or installing the components indicated in the table of contents by an astarisk (*), use utmost care so
as not to apply any strong shock to SRS components.
NOTE
The SRS includes the following components: SRS-ECU, SRS warning lamp, air bag module, clock spring and interconnecting
wiring. Other SRS-related components (that may have to be removed/installed in connection with SRS service or maintenance) are
indicated in the table of contents by an asterisk (*).

Outline of Change

The following service procedures have been incorporated.

Specific gravity of the battery fluid1.220 – 1.290 [20C]
ON-VEHICLE SERVICE
FLUID LEVEL AND SPECIFIC GRAVITY CHECK
1. Inspect whether or not the battery fluid is between the
UPPER LEVEL and LOWER LEVEL marks.
2. Use a hydrometer and thermometer to check the specific
gravity of the battery fluid.
Standard value: 1.220–1.290 [20C]
The specific gravity of the battery fluid varies with the
temperature, so use the following formula to calculate
the specific gravity for 20C. Use the calculated value
to determine whether or not the specific gravity is
satisfactory.

MUT-II is impossible.
Even if driver’s side door is opened, key hole
illumination lamp does not illuminate.254-7
While key hole illumination lamp is illuminated,
ignition key is turned to the ON position but key hole
illumination lamp does not switch off. (However, it
switch off after 10 seconds.)354-8
Key reminder warning
buzzer systemWhile the key reminder warning buzzer is sounding,
the ignition key is turned to the ON position but the
sound dose not stop. (However, it stops when the
driver’s side door is closed.)354-8
The key reminder warning buzzer dose not stop
sounding even if the key is removed. (However, it
stops when the driver’s side door is closed.)454-9
The key reminder warning buzzer does not sound
ever if the driver’s side door is opened while the key
is still inserted. (However, the ignition key should be
in the OFF position.)554-10
NOTE
If every input signal can not be checked with the MUT-II, a diagnosis circuit system failure is probably
the cause.
