INSPECTION OF ECM / PCM, IMMOBILIZER
CONTROL MODULE AND ITS CIRCUIT
ECM / PCM, Immobilizer Control Module and its circuit can be
checked at ECM / PCM wiring couplers and Immobilizer Control
Module wiring coupler by measuring voltage and resistance. De-
scribed here is only inspection of Immobilizer Control Module. For
inspection of ECM / PCM, refer to ªSECTION 6E1 or 6E2º.
CAUTION:
Immobilizer Control Module cannot be checked by itself. It
is strictly prohibited to connect voltmeter or ohmmeter to
Immobilizer Control Module with coupler disconnected
from it.
Voltage Check
1) Remove Immobilizer Control Module from body with ignition
switch OFF, referring to p. 8G-24.
2) Connect Immobilizer Control Module coupler to Immobilizer
Control Module.
3) Check voltage at each terminal of coupler connected.
NOTE:
As each terminal voltage is affected by the battery voltage,
confirm that it is 11 V or more when ignition switch is ON.

10A-4 SEAT BELT
INSPECTION
Seat belts and attaching parts can affect the vital components and
systems of a vehicle. Therefore, they should be inspected carefully
and replaced with genuine parts only.
Seat belt
The seat belt webbing or strap should be free from damage.
Fully extend the seat belt to make sure there are no twists or tears
in it.
Retractor assembly
Let the seat belt retract fully to confirm its easy retraction.
The retractor assembly should lock webbing when pulled quickly.
The retractor assembly should lock webbing even when tilted
(approx. 15) toward the fore and aft or right and left directions.
Anchor bolt
Inspect all seat belt anchor bolts to verify that they are secure.
All anchor bolts should be secure and torqued to specification.
Belt latch
Belt latch should be secure when latched.
Inspect the seat belt buckle, ensuring that it locks and unlocks
easily.
After buckling the seat belt, tug sharply on the belt, checking that
the buckle remains locked.
Warning system
Check driver side seat belt strap switch for continuity by using ohm-
meter.
Without inserted buckle tongue to buckle catch:
Terminal ªAº and ªBº: Continuity
With inserted buckle tongue to buckle catch:
Terminal ªAº and ªBº: No continuity ()
As to seat belts with ALR (other than driver side seat belt), check
them as follows in addition to above check.
With vehicle at stop, pull seat belt all the way out, let it retract a
little and try to pull it. It should not be pulled out, that is, it should
be locked where retracted.
Let seat belt retract to its original state. Next, pull it half way out,
let it retract a little and try to pull it again. It should be pulled out
smoothly, that is it should not be locked at this time.

DIAGNOSIS
WARNING:
To avoid deployment when troubleshooting the air bag system, do not use electrical test equipment
such as a battery powered or AC powered voltmeter, ohmmeter, etc., or any type of electrical equipment
other than that specified in this manual. Do not use a non-powered probe type tester.
Instructions in this manual must be followed carefully, otherwise personal injury may result.
DIAGNOSTIC TROUBLE CODES
The ªAir Bag Diagnostic System Checkº must always be the starting point of any air bag system diagnosis. The
ªAir Bag Diagnostic System Checkº checks for proper ªAIR BAGº warning lamp operation and checks for air bag
diagnostic trouble codes using the Tech-1 (scan tool) or on-board diagnosis function.
Current diagnostic trouble code ± Malfunction that are presently being detected.
History diagnostic trouble code ± All malfunction detected since the last time the history memory was cleared.
USE OF SPECIAL TOOLS
WARNING:
To avoid deployment when troubleshooting the air bag system, do not use electrical test equipment
such as a battery powered or AC powered voltmeter, ohmmeter, etc., or any type of electrical equipment
other than that specified in this manual. Do not use a non-powered probe type tester.
Instructions in this manual must be followed carefully, otherwise personal injury may result.
You should be familiar with the tools listed under ªSpecial Toolsº in this section. You should be able to measure
voltage and resistance. You should be familiar with proper use of a scan tool such as the Tech-1 Diagnostic Com-
puter, Driver/Passenger Load Tool, Connector Test Adapter Kit and the Digital Multimeter.
Special Tool (Connector Test Adapter Kit)
(A): 09932-76010
This must be used whenever a diagnostic procedure requests
checking or probing a terminal.
Using the appropriate adapter in the special tool will ensure that no
damage to the terminal will occur from the multimeter probe, such
as spreading or bending.
The adapter will also give an idea of whether contact tension is suffi-
cient, helping to find an open or intermittent open due to poor termi-
nal contact.

AIR BAG DIAGNOSTIC SYSTEM CHECK
WARNING:
To avoid deployment when troubleshooting the air bag system, do not use electrical test equipment
such as a battery powered or AC powered voltmeter, ohmmeter, etc., or any type of electrical equipment
other than that specified in this manual. Do not use a non-powered probe type tester.
Instructions in this manual must be followed carefully, otherwise personal injury may result.
CAUTION:
The order in which diagnostic trouble codes are diagnosed is very important. Failure to diagnose the
diagnostic trouble codes in the order specified may result in extended diagnostic time, incorrect diag-
nosis and incorrect parts replacement.
The diagnostic procedures used in this section are designed to find and repair air bag system malfunctions.
To get the best results, it is important to use the diagnostic flow tables and follow the sequence listed below.
A. PERFORM THE ªAIR BAG DIAGNOSTIC SYSTEM CHECK FLOW TABLEº
The ªAir Bag Diagnostic System Check Flow Tableº must be the starting point of any air bag system diagnostics.
The ªAir Bag Diagnostic System Check Flow Tableº checks for proper ªAIR BAGº warning lamp operation, the
ability of the SDM to communicate through ªAIR BAGº warning lamp and whether air bag diagnostic trouble
codes exist.
B. REFER TO THE PROPER DIAGNOSTIC TABLE AS DIRECTED BY THE ªAIR BAG DIAGNOSTIC SYSTEM
CHECK FLOW TABLEº.
The ªAir Bag Diagnostic System Check Flow Tableº will lead you to the correct chart to diagnose any air bag
system malfunctions. Bypassing these procedures may result in extended diagnostic time, incorrect diagnosis
and incorrect parts replacement.
C. REPEAT THE ªAIR BAG DIAGNOSTIC SYSTEM CHECK FLOW TABLEº AFTER ANY REPAIR OR DIAGNOS-
TIC PROCEDURES HAVE BEEN PERFORMED.
Performing the ªAir Bag Diagnostic System Check Flow Tableº after all repair or diagnostic procedures will en-
sure that the repair has been made correctly and that no other malfunctions exist.
