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 

P.52B-176

.

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 

P.52B-178

. Then go to Step 6  .

NO : 

Go to Step 5.

STEP 5. Connector check: SRS-ECU connector
