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 .

DTC 21: DRIVE
R-SIDE AIR BAG MODULE SHORT CIRCUIT
1. Before proceeding, see AIR BAG SAFETY PRECAUTIONS
. If DTC 34 is
retrieved, go to next step. If DTC 34 is not retrieved, go to step 3 .
2. Inspect SRS ECU connector C-26. See SRS ELECTRONIC CONTROL
UNIT (SRS ECU)
under REMOVAL & INSTALLATION. See Fig. 19
. If
SRS ECU connector C-26 is connected correctly, go to next step. If SRS ECU
connector is not connected properly, install connector correctly. Go to step 8 .
3. Disconnect negative battery cable. Disconnect, then reconnect SRS ECU
connector C-26, lower clockspring connector C-307 and driver-side air bag
module connector C-305. See DRIVER
-SIDE AIR BAG MODULE &
CLOCKSPRING
under REMOVAL & INSTALLATION. Connect negative
battery cable. Using scan tool, erase then retrieve DTCs. If DTC 21 is
retrieved, go to next step. If DTC 21 is not retrieved, system is normal at this
time.
4. Disconnect negative battery cable. Connect Resistor Harness (MB991866) to
terminals of upper clockspring connector C-306 by backprobing connector.
Connect Load Resistor (MB991865) to resistor harness. Connect negative
battery cable. Using scan tool, erase then retrieve DTCs. If DTC 21 is
retrieved, go to next step. If DTC 21 is not retrieved, replace driver-side air bag
module. Go to step 8 .
5. Disconnect negative battery cable. Connect resistor harness and load resistor to
terminals No. 3 and 4 of clockspring connector C-307 by backprobing
connector. See Fig. 24
. Connect negative battery cable. Using scan tool, erase
then retrieve DTCs. If DTC 21 is retrieved, go to next step. If DTC 21 is not
retrieved, replace clockspring. Go to step 8 .
6. Disconnect SRS ECU connector C-26 and clockspring connector C-307. Insert
a cable tie or similar insulator between terminals No. 11 (Yellow/Black wire)
and No. 12 (Yellow wire) of SRS ECU connector to release shorting bar. See
Fig. 21
. Check for continuity between terminals No. 11 and 12. If continuity
exists, go to next step. If continuity does not exist, erase, then retrieve DTCs
using scan tool. If DTC 21 is retrieved, replace SRS ECU. Go to step 8 .
7. Check wire harness between SRS ECU connector C-26 and lower clockspring
connector C-307 for a short circuit. If wire harness is okay, go to next step. If
wire harness has a short circuit, replace wire harness. Go to next step

8. Reconnect all SRS components. Activate air bag system. Using scan tool, erase
then retrieve DTCs. If DTC 21 is retrieved, go to step 1 . If DTC 21 is not
retrieved, system is normal at this time. Intermittent condition may exist.
