Power-supply
Failure code
$9032 Low power-supply voltage for SRS safety airbag system electronic-control unit
Test condition Warning
The test condition of this failure is the failure code that may not emerge before the test, DTC conducts the test,
and the preparatory work must be done before the test because the damage to working personnel or system
may be caused by the incorrect op eration during the test.
The voltage for SRS safety airbag system unit connector clip is stitch 5 and 6 is under 9V
Possible
caus es Accumulator low voltage
Failure with the wiring harness between accumulator and SRS safety airbag system electronic-control unit
Procedure Test Operation
Yes Next step
1 Check accumulator
Test accumulator voltage
Is the voltage above 9V No Accumulator low voltage, test the
recharging/discharging system
Yes Next step
2 Check the wiring harness between accumulator and fuse
panel
Remove fuse panel without releasing the connector clips
Place the ignition switch in ON position
Test the potential of two fuse corresponding contactors, the
potential above 9V? No Check the wiring harness
Yes Next step
3 Check the wiring harness between fuse panel and SRS
safety airbag system unit connector clip
Warning:
If not correctly handled, the safety airbag module as well
as pretension safety belt may possibly be trigged, released
and tensioned, thus make serene damage to people.
Ther efor e, pleas e carefully r ead the r epairing warning
before trouble handling. Please take references in safety
airbag system repairing warning
Place the ignition switch in LOCK position
Release accumulator negative wire and wait for 1 minute
plus
Remove steering pillar shell
Release the clock spring connection clips
Remove the PAB trim cover, glove box (passengers’ side
safety airbag is under the trim cover)
Release passengers’ side safety airbag module connector
clips
Release all SRS safety airbag system unit connector clips
Install back the accumulator negative wire,
Place the ignition switch in ON position
Is the potential of SRS safety airbag system unit connector
clips stitch 5,6(grounding) above 9V? No Replace wiring harness

Do the troubleshooting if the alarm lamp re-illuminates after its extinguishments following the 6-second-flashing (or it keeps
illuminating from the very beginning)
10. Test
a. Driver’s side airbag module test (Figure8-3)
Check the following items and replace the corresponding safety airbag module part with anything abnormal with a new one.
Abandon the safety airbag’s old parts after its release according to the instructed procedure.
Caution
Do not jam the clock spring wiring harness during the steering wheel and safety airbag module assembly installation.
After the installation, rotate the steering wheel to left and right positions as enough as possible to confirm whether something
abnormal is with it.
d. Post-installation test.
lightly rotate the steering wheel to the left and right to confirm whether something abnormal and noises will arise.(Driver’s side
safety airbag module, clock spring)
Place the ignition switch in ON place.
SRS alarm lamp flashes in 6 seconds and then extinguishes.
Caution
If without the clock spring central involution, the steering wheel will not be able to rotate at midway, or the clock spring
circuit will be damaged so that jeopardize SRS safety airbag’s normal activities.
The spacer must be removed after replacing a clock spring with a new one, otherwise it will damage the clock spring.
c. Steering wheel and safety airbag module assembly installation.
Install the steering wheel and safety airbag module assembly after clock spring’s central involution.

Caution
The safety airbag module (squib) circuit resistance can even not be tested by the designated tester.
When testing the resistance with an experimental instrument, sometimes the improper release will be caused by the
static interference because of the current in explosion pipe and cause some major damaging accidents.
Whether depression, crack or deformation is with the shroud.
Whether the joint is broken and the terminal is deformed.
Whether depression, crack or deformation is with the gas generator shield.
Safety airbag module. Installation status.
Caution
Replace the safety airbag with depression, crack or deformation with a new one. Its old parts must be abandoned after
its release.

Safety airbag-27
b. Clock spring test (figure 8.5,figure 8.6)
Check the following items and replace the clock spring with anything abnormal (even it is quite tiny) with a new one
Whether the joint and protection tube are broken and the terminal is deformed.
Whether the shield is damaged.
Check the connection between clock spring’s upper joint terminal and it’s corresponding bottom terminal.
Plug in a thin probe from the 3# joint of clock spring.
Caution
Do not directly plug in the probe from the bottom of the joint.
Figure 85 As showed in Figure 8.5,Plug a thin probe into the current tester to check the connection of the terminal.
