Troubleshooting (cont'dl
SRS Indicator Light Stays on Continuously
NOTE: Before troubleshooting, make sure that battery
voltage is 12 V or mo.e. Otherwise you'll obtain wrong
test readings.
1. Make a photocopy of the chart on page 23-283,
2. Connect Test Harness A to the SRS unit as shown.
Tu.n the ignition switch ON (lll.
. Voltages in the chart assume the car's "battery
voltage" is about 12 volts. Less than 12 volts will
result in different or possibly talse readings.
. Do not disconnect the airbags ftom the circuit
when checking SRS unit voltages.
First, check for voltage between Test Harnoss
Terminal No. 12 (+) and ground (-).
. lf no voltage is indicated, go to step I and contin-
ue checking all the other terminals.
o lf vottsge is indicated, there is a poor ground at
the SRS unit. Read the following NOTE, and then
go on to step 5.

TEST HANNESS
NOTE: The original .adio has a coded theft protection
circuit. Be sure to get the customer's code number
before disconnecting the battery cables.
Before disconnecting any pan of the SRS wire har-
ness, connect the short connecto(s) {RED) to the
airbag(s) (see page 23-2721.
Connect Test Harness B between the SRS unit and
SRS main harn€ss 18-P connector.
7. Check for continuitv between the 85 terminal and
body ground, and the Bl5 terminal and body
ground.
TEST HARNESS B07MAZ - SPqrS{X)
lf there is continuity at either terminal, the SRS
unit is faulty. Replace it and check the voltages
according to the chan on page 23-283.
lf there is no continuity at either terminal, the
SRS unit ground, the SRS unit component
grounds or the SRS main harness is faulty
Check the grounds (check wire and control unit
mounting bolts) and, if necessary, replace th€
SRS main harness. Then check the voltages
according to the chart on page 23-283

r The SRS unit is faultY. Substitute a known-good SRS
unit and recheck the voltages according to the chart
on page 23-283.

. Short in dash sonsor
. Opsn in both cowl sgnsor contacts
NOTE: The original radio has a coded theft protection
circuit. Be sure to get the customer's code number
before disconnecting the battery cables.
1. Disconnect the battery negative cable and then the
positive cable. Then connect the short connectots(s)
(RED) to the airbag(s) (see page 23-272).

3. Reconnect the driv€r's airbag connector, then check
continuity between the B1 terminal and body
ground, and b€twesn the 87 terminsl and body
grounq,
TEST HABT{ESS B
. lf there is continuity at either terminal, go to step
o.
. lf there is no continuity at sither terminal'
- go to step 5 (without front passonge/s airbag)'
- go to step il (with front passenger's airbag)'
Reconnect the front passonger's sirbag connector,
then check continuity betwo€n ihs 82 t€rminal and
body ground, and between the 88 terminal and
body ground.
lf there is continuity at either terminal, go to step
10.
lf there is no continuity at either terminal, go to
step 5.

sensors
Mode D: Open in ono da3h sensol
NOTE: The original radio has a coded theft protection
circuit. Be sure to get the customer's code number
before disconnecting the battery cables
1. Disconnect the battery negative cable and then the
positive cable. Then connect the short connector(s)
to the airbag(s) (see page 23'2721.
2. Connect Test Harness B between the SRS unit and
SRS main harness 18-P connector.

3. Measure the resistance between the left dash sen-
sor terminals 812 and 816, and between the right
dash sensor terminals 84 and 86.
lf resistance is more than 5 kO for eiiher set of
terminals, go to step 4.
lf resistance is less than 5 kO tor both sets of ter-
minals, the SRS unit is faulty. Substitute a
known-good SRS unit and recheck the voltages
according to the chart on page 23-283.
