STEP 2. Check the harness wires for open circuit or short
circuit between SRS-ECU connector E-07 (terminal No.40
and 42) and side impact sensor (RH) connector F-19
(terminal No.1 and 2).
NOTE: After inspecting intermediate connector E-16, inspect
the wiring harness. If the intermediate connector E-16 is dam-
aged, repair or replace it (Refer to GROUP 00E, Harness Con-
nector Inspection
). Then go to Step 3.
Q: Are the harness wires between SRS-ECU connector
E-07 (terminal No.40 and 42) and side impact sensor
(RH) connector F-19 (terminal No.1 and 2) in good
condition?
YES : Erase the diagnostic trouble code memory, and check
the diagnostic trouble code. If DTC 94 sets, replace
the SRS-ECU (Refer to
). Then go to Step
NO : Repair the harness wires between SRS-ECU
connector E-07 and side impact sensor (RH)
connector F-19. Then go to Step 3.
STEP 3. Recheck for diagnostic trouble code.
Q: Is DTC 94 set?
YES : Return to Step 1.
NO : 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
).

DIAGNOSIS
Communication with scan tool MB991502 is not
possible (Communication is not possible with
SRS).
1
When the ignition switch is turned to the "ON"
position (engine stopped), the SRS warning
light does not illuminate.
Refer to DTC No.43.
After the ignition switch is turned to the "ON"
position the SRS warning light does not go off
within approximately seven seconds.
Refer to DTC No.43.

.
CIRCUIT OPERATION
• The SRS-ECU is powered from the ignition
switch (IG1).
• The SRS-ECU power is supplied from two cir-
cuits. Even if one circuit is shut off, the air bag
can inflate.
• The SRS system diagnosis can be done by con-
necting scan tool MB991502 to the data link con-
nector.
.
TECHNICAL DESCRIPTION (COMMENT)
If communication is not possible with the SRS only,
the cause is probably an open circuit in the on-board
diagnostic output circuit of the SRS or in the power
circuit (including ground circuit).
.
TROUBLESHOOTING HINTS
• Damaged wiring harnesses or connectors
• Malfunction of the SRS-ECU
.
DIAGNOSIS
STEP 1. Check that the scan tool can communicate with
the other systems.
Q: Can the scan tool communicate with the other systems?
YES : Go to Step 2.
NO : Refer to GROUP 13A, Diagnosis
