TROUBLESHOOTING
SUPPLEMENTAL RESTRAINT SYSTEM (SRS)
52B-19
DIAGNOSIS CODE SET CONDITIONS
These diagnosis codes are set if these is abnormal
resistance between the input terminals of the front
impact sensors.
The most likely causes for these codes to be set are
shown in the table below:
PROBABLE CAUSES
•
Malfunction of the front impact sensor
•
Damaged wiring harnesses or connector.
•
Malfunction of the SRS-ECU.
DIAGNOSIS PROCEDURE
STEP 1. Check the front impact sensor.
(1) Measure the resistance between terminals and
check whether it is within the standard value.
Standard value: 820
±
82
Ω
(2) Check for continuity between the terminal and
bracket.
OK: No continuity
Q: Does the resistance meet the value above, and is
there no continuity?
YES :
Go to Step 2.
NO :
Replace front impact sensor. Refer to
Code No.
Trouble causes
11
•
Short circuit in front impact sensor or harness
•
Short circuit in front impact sensor harness leading to the vehicle body
eart.
•
Short circuit in front impact sensor harness leading to the power suppl.
12
•
Open circuit in either left or right from impact sensor or harnes.
•
Short circuit in front impact sensor harness leading to the power suppl.
13
•
Open circuit in both left and right front impact sensor or harness
•
Short circuit in front impact sensor harness leading to the power
supply

STEP 2. Measure the resistance at SRS-ECU
connector C-115.
(1) Disconnect SRS-ECU connector C-115 and
measure at the harness side (rear 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) Measure the resistance between terminal 3 and
terminal 4.
OK: 820
±
82
Ω
Q: Is the check result normal?
YES :
Go to Step 4.
NO :
Go to Step 3.
STEP 3. Connector check: SRS-ECU connector
C-115, front impact sensor (LH) connector A-17
and intermediate connector C-116

Q: Is the check result normal?
YES :
Check the harness wires for open or short
circuit between SRS-ECU connector C-115
(terminal No.3 and 4) and front impact
sensor (LH) connector A-17 (terminal No.1
and 2), and repair if necessary. Then go to
Step 6.
NO :
Repair or replace it. Then go to Step 6.
STEP 4. Measure the resistance at SRS-ECU
connector C-115.
(1) Disconnect SRS-ECU connector C-115 and
measure at the harness side (rear 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) Measure the resistance between terminal 1 and
terminal 2.
OK: 820
±
82
Ω
Q: Is the check result normal?
YES :
Erase the diagnosis code memory, and
check the diagnosis code. If diagnosis code
11, 12 or 13 sets, replace the SRS-ECU.
Refer to
NO :
Go to Step 5.
STEP 5. Connector check: SRS-ECU connector
C-115, front impact sensor (RH) connector A-28
and intermediate connector C-14
