SUPPLEMENTAL RESTRAINT SYSTEM (SRS)
Troubleshooting
CONTINUED FROM PREVIOUS PAGE
Turn the ignition key to the “LOCK” position,
disconnect the negative battery cable and tape the
terminal.
Caution
Wait at least 30 seconds after disconnecting the
battery cable before doing any further work. The
SRS system is designed to retain enough voltage
to deploy the air bag for a short time even after
the battery has been disconnected, so serious
injury may result from unintended air bag deploy-
ment if work is done on the SRS system im-
mediately after the battery cable is disconnected.
(2) Remove the rear console assembly. (Refer to
GROUP 52A Floor Console.)
(3) Use a screwdriver to push in the lock spring of the
lock lever of the SRS diagnosis unit to unlock the lock
lever.
Caution
A double-lock mechanism is employed for the
connector of the SRS diagnosis unit, so care must
be taken not to damage it by using excessive
force or by not disconnecting it correctly.
(4) Disconnect the red connector from the SDU
while pressing down the lock of the connector.
(Refer to
Lock spring
Clock spring
Connect the red connector of the SRS Check
Harness to the SDU instead of the now-disconnected
harness-side connector of the SDU, which were
connected to the air bag module through the
clock spring.
NOTE
SRS Check Harness
A resistor that corresponds to the resistance
of the air bag module and the wiring resis-
tance is connected between the terminals of the
connector
of the SRS Check Harness.
(2) Make the double locking.
NOTE
If double locking cannot be made, the connector is
incorrectly or incompletely inserted; re-check to
insert the connector correctly and securely.
