ABS <4WD> -On-vehicle Service35B-31
WHEN THE BATTERY IS FLAT
If the engine is started using a booster cable when the battery
is completely flat, and the vehicle is then driven without waiting
for the battery to be recharged, the engine may misfire and it
may not be possible to drive the vehicle. This is because the
ABS consumes a large amount of current when carrying out its
initial checks. If this happens, recharge the battery fully.
Caution
The vehicle posture will be unstable during braking, so
do not drive the vehicle with the ABS-ECU connector
disconnected or with the ABS not operating for any other
reason.

Inspection Procedure 1
Both of the electric retractable mirrors do not work at all.
Probable cause
The Mirror control unit controls the electric retractable mirror based on input
signals from the following switches.

SRS -Post-collision Diagnosis52B-23
POST-COLLISION DIAGNOSIS
Whether or not the air bags have deployed, check and service
the vehicle after collision as follows:
SRS-ECU MEMORY CHECK
1. Connect the MUT-
IIto the diagnosis connector. (Refer
to GROUP 00 – How to Use Troubleshooting/Inspection
Service Points.)
Caution
Refer to that the ignition switch is LOCK(OFF) when
connecting or disconnecting MUT-II
.
2. Read (and write down) all displayed diagnosis codes.
(Refer to P.52B-7.)
NOTE
If battery power supply has been shut down by the
collision, the MUT-
IIcannot communicate with the
SRS-ECU. Check and, repair if necessary, the instrument
panel wiring harness before the next job.
3. Use the the MUT-
IIto read the data list (how long trouble(s)
have continued and how often memory have been
erased).
Data list

(approximately 7 days)
94How long problem(s) have lasted (How long it takes
from the first air bag squib igniting signal till now.)
4. Erase the diagnosis codes and after waiting 5 seconds
or more read (and write down) all displayed diagnosis
codes. (Refer to P.52B-7.)
REPAIR PROCEDURE
DEPLOYED DRIVER’S AND FRONT PASSENGER’S AIR
BAGS
1. Replace the following parts with new ones.
DSRS-ECU (Refer to P.52B-30.)
DDriver’s air bag module (Refer to P.52B-32.)
DFront passenger’s air bag module (Refer to P.52B-32.)
2. Check the following parts and replace if malfunction is
found:
DClock spring (Refer to P.52B-32.)
DSteering wheel, steering column and intermediate
joint
(1) Check the wiring harness (built into steering
wheel) and connectors for damage, and terminals
for deformation.
(2) Check the driver’s air bag module for proper
installation to the steering wheel.
