SRS AIR BAG DIAGNOSIS
TSB Revision
SUPPLEMENTAL RESTRAINT SYSTEM (SRS)
52B-65
STEP 1. Check the ground line at the SRS-ECU connector
C-24.
(1) Disconnect SRS-ECU connector C-24 and measure at the
harness side (rear side).
(2) Measure the resistance between terminal 7 and ground.
• It should be less than 2 ohms.
Q: Does continuity exist?
YES : Go to Step 3.
NO : Go to Step 2.

STEP 2. Check the harness wires between SRS-ECU
connector C-24 (terminal No.7) and ground.
NOTE: After inspecting intermediate connector D-13, inspect
the wiring harness.
If intermediate connector D-13 is damaged, repair or replace it.
Refer to GROUP 00E, Harness Connector Inspection
Then go to Step 6.
Q: Is the harness wires between SRS-ECU connector C-24
(terminal No.7) and ground in good condition?
YES : Go to Step 6.
NO : Repair or replace the harness wire. Then go to Step 6.

STEP 3. Measure the ignition switch (IG
1
) line voltage at
the SRS-ECU connector C-24.
(1) Disconnect SRS-ECU connector C-24 and measure at the
harness side (rear side).
(2) Turn the ignition switch to the "ON position."
(3) Measure the voltage between terminal 13 or 16 and ground.
• Voltage should measure 9 volts or more
Q: Is the voltage between terminal 13 or 16 and the ground
9 V or more?
YES : Go to Step 5.
NO : Go to Step 4.

STEP 4. Check the harness wires between ignition switch
(IG
1
) and SRS-ECU connector C-24 (terminal No.13 and
16).
NOTE: After inspecting intermediate connectors D-08, D-13,
D-14, inspect the wiring harness.
If intermediate connectors D-08, D-13, D-14 are damaged,
repair or replace them. Refer to GROUP 00E, Harness Con-
nector Inspection
.
Then go to Step 6.
Q: Are the harness wires between ignition switch (IG1) and
SRS-ECU connector C-24 (terminal No.13 and 16) in
good condition?
YES : Go to Step 6.
NO : Repair or replace the harness wire. Then go to Step 6.
