SRS AIR BAG DIAGNOSIS

TSB Revision

SUPPLEMENTAL RESTRAINT SYSTEM (SRS)

52B-203

NOTE: After inspecting junction block connector D-210, D-209 
and D-208 inspect the wiring harness. If the junction block con-
nector D-210, D-209 or D-208 is damaged, repair or replace it 
(Refer to GROUP 00E, Harness Connector Inspection 

P.00E-2

). Then go to Step 8   .

Q: Are the harness wires between SRS-ECU connector 

E-08 (terminal No.13 and 16) and ignition switch 
connector D-204 (terminal No.2) in good condition?
YES : 
Go to Step 8.
NO :  Repair the harness wires between SRS-ECU 

connector E-08 and ignition switch connector D-204. 
Then go to Step 8.

STEP 8. Retest the system.
Q: Does the scan tool communicate normally with the SRS 

system?
YES : 
The procedure is complete. (If no malfunctions are 

not found in all steps, an intermittent malfunction is 
suspected. Refer to GROUP 00, How to Use 
Troubleshooting/Inspection Service Points 

− How to 

Cope with Intermittent Malfunction 

P.00-6

).

NO :  Return to Step 1.

POST-COLLISION DIAGNOSIS

M1524001100539

To inspect and service the SRS after a collision (whether or not 
the air bags have deployed), perform the following steps.

SRS-ECU MEMORY CHECK

Required Special Tools:

• MB991958: Scan Tool (MUT-III Sub Assembly)

• MB991824: Vehicle Communication Interface (V.C.I.)

• MB991827: MUT-III USB Cable

• MB991911: MUT-III Main Harness B (Vehicles without 

CAN communication system)

CAUTION

To prevent damage to scan tool MB991958, always turn the 
ignition switch to the "LOCK" (OFF) position before con-
necting or disconnecting scan tool MB991958.
1. Connect scan tool MB991958 to the data link connector 

(16-pin).

2. Read (and write down) all displayed diagnostic trouble 

codes (Refer to 

P.52B-21

).

NOTE: If the battery power supply has been disconnected or 
disrupted by the collision, scan tool MB991958 cannot com-
municate with the SRS-ECU. Check the battery then check 
and, if necessary, repair the front wiring harness and the 
body wiring harness before proceeding.

3. Read the data list (fault duration and how many times 

memories are erased) using scan tool MB991958.

Data list

4. Erase the diagnostic trouble codes and, after waiting five 

seconds or more, read (and write down) all displayed 
diagnostic trouble codes (Refer to 

P.52B-23

).
