STEP 2. Check the communication line between the
SRS-ECU and the scan tool.
(1) Disconnect SRS-ECU connector E-08 and data link
connector D-118 and measure at the wiring harness side.
CAUTION
Do not insert a test probe into the terminal of the SRS-ECU
connector E-08 from its front side directly as the connector
contact pressure may be weakened.
(2) Check for continuity between the following terminals.
Between connector E-08 terminal 20 and connector D-118
terminal 7
It should be less than 2 ohms.
Q: Does continuity exist?
YES : Go to Step 3.
NO : Go to Step 5.

STEP 3. Check the ground circuit to the SRS-ECU.
(1) Disconnect SRS-ECU connector E-08, and measure at the
wiring harness side.
CAUTION
Do not insert a test probe into the terminal from its front
side directly as the connector contact pressure may be
weakened.
(2) Check for continuity between E-08 harness terminal 7 and
body ground.
It should be less than 2 ohms.
Q: Does continuity exist?
YES : Go to Step 4.
NO : Go to Step 6.
STEP 4. Check the power supply circuit to the SRS-ECU.
(1) Disconnect SRS-ECU connector E-08, and measure at the
wiring harness side.
(2) Connect the negative battery terminal.
(3) Turn the ignition switch to the "ON" position.
CAUTION
Do not insert a test probe into the terminal from its front
side directly as the connector contact pressure may be
weakened.
(4) Measure the voltage between terminals 13, 16 and body
ground.
Voltage should measure 9 volts or more.
Q: Is the measured voltage within the specified range?
YES : Recheck the trouble symptom. If it is not solved,
replace the SRS-ECU (Refer to
). Then go
to Step 8.
NO : Go to Step 7.

STEP 5. Check the harness wires between SRS-ECU
connector E-08 (terminal No.20) and data link connector
D-118 (terminal No.7).
NOTE: After inspecting intermediate connector D-29 inspect
the wiring harness. If the intermediate connector D-29 is dam-
aged, repair or replace it (Refer to GROUP 00E, Harness Con-
nector Inspection
).. Then go to Step 8.
Q: Are the harness wires between SRS-ECU connector
E-08 (terminal No.20) and data link connector D-118
(terminal No.7) in good condition?
YES : Go to step 8.
NO : Repair the harness wires between SRS-ECU
connector E-08 and data link connector D-118. Then
go to Step 8.

STEP 6. Check the harness wire between SRS-ECU
connector E-08 (terminal No.7) and ground.
Q: Is the harness wire between SRS-ECU connector E-08
(terminal No.7) and ground in good condition?
YES : Go to Step 8.
NO : Repair the harness wire between SRS-ECU
connector E-08 and ground. Then go to Step 8.
STEP 7. Check the harness wires between SRS-ECU
connector E-08 (terminal No.13 and 16) and ignition switch
connector D-204 (terminal No.2).
