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

8.Record you. voltage readings. for each terminal, inthe row of blank boxes near the top of the chart.
Compare each reading with the voltage ranges list-ed in the column below it. lf ths reading is within arange, circle that range.
