DIAGNOSTIC TESTS INSPECTION PROCEDURE 1 No communication between scan tool and all systems is most likely in power
supply or ground circuits to Data Link Connector (DLC). Check wire harness and
connectors for damage and loose connections. See WIRING DIAGRAMS
.
INSPECTION PROCEDURE 2 1. Before proceeding, see AIR BAG SAFETY PRECAUTIONS
. Disconnect
SRS ECU connector C-26. See SRS ELECTRONIC CONTROL UNIT
(SRS ECU)
under REMOVAL & INSTALLATION. See Fig. 19
. Measure
resistance between SRS ECU connector C-26, terminal No. 20 (Orange/Blue
wire) and Data Link Connector (DLC), terminal No. 7 (Orange/Blue wire). See
Fig. 20
& Fig. 21
. If resistance is more than 2 ohms, go to next step. If
resistance is 2 ohms or less, go to step 4 .
2. Measure resistance between SRS ECU connector C-26, terminal No. 15 (Black
wire) and ground. If resistance is less than 2 ohms, go to next step. If resistance
is 2 ohms or more, go to step 5 .
3. Connect negative battery cable. Turn ignition on. Measure voltage between
ground and SRS ECU connector C-26, terminals No. 13 (Black/White wire)
and No. 16 (Black/Yellow wire). If voltage is less than 9 volts at either
terminal, go to step 6 . If voltage at both terminals is 9 volts or more, recheck
trouble s
ymptom. If s
ymptom still exists, re
place SRS ECU. Go to ste
p 7 .

4. Inspect wire harness between SRS ECU connector C-26, terminal No. 20
(Orange/Blue wire) and Data Link Connector C-23, terminal No. 7
(Orange/Blue wire), including connector C-104, for damage, loose connectors
or poor connections. If wire harness is okay, go to step 7 . If wire harness is not
okay, replace wire harness. Go to step 7 .
5. Inspect wire harness between SRS ECU connector C-26, terminals No. 15
(Black wire) and ground. If wire harness is okay, go to step 7 . If wire harness
is not okay, replace wire harness. Go to step 7 .
6. Inspect wire harness between SRS ECU connector C-26, terminals No. 13
(Black/White wire) and No. 16 (Black/Yellow wire) and ignition switch
connector C-308, including connectors C-211 and C-215. See Fig. 22
. If wire
harness is okay, go to next step. If wire harness is not okay, replace wire
harness. Go to step 7 .
7. Connect all SRS connectors. If scan tool communicates normally with SRS,
repair is complete. If communication is not normal, intermittent condition may
exist.
