SRS Warning Light System (Always Lit Up, when ignition switch in
LOCK position)
CIRCUIT DESCRIPTION
The SRS warning light is located on the combination meter.
When the supplemental restraint system is normal, the SRS warning light ligh\
ts up for approx. 6 seconds after
the ignition switch is turned from LOCK position to ACC or ON position, and\
then turns off automatically.
If there is a malfunction in the supplemental restraint system, the SRS wa\
rning light lights up to inform the driver
of the abnormality.
When terminals Tc and E
1 of the DLC2 are connected, the diagnostic trouble code is displayed by \
the blinking
of the SRS warning light.
DIAGNOSTIC CHARTDIAGNOSTIC CHART
HINT: If the SRS warning light is always lit up by a DTC check procedure, per\
form Tc T erminal circuit check proce-
dure (See page RS±121).

Tc Terminal Circuit
CIRCUIT DESCRIPTION
By connecting terminal Tc and E1 of the DLC1 or DLC2, the center airbag sensor assembly is set in the di\
agnos-
tic trouble code output mode. The diagnostic trouble codes are displayed\
by the blinking of the SRS warning
light.
DIAGNOSTIC CHARTDIAGNOSTIC CHART
Troubleshooting for this system is different depending on whether the diagnostic trouble code is not displayed\
SRS warning light is always lit up with a DTC check procedure, or is displa\
yed without a DTC check procedure.
Confirm the problem symptoms first before selecting the appropriate troubleshoo\
ting procedure.
HINT: If the diagnostic trouble code is not displayed or SRS warning light is\
always lit up with a DTC check proce-
dure perform the following troubleshooting:
