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 operation during the test.

The voltage for SRS safety airbag system unit connector clip is stitch 5 and 6 is under 9V

Possible

causes

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.

Therefore, please carefully read the repairing 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

SRS safety airbag system driver’s side airbag relative wiring harness shorting or shutoff

Possible

causes

Driver’s side safety airbag module failure
Clock spring internal failure
Failure of circuit connector clips between clock spring and SRS safety airbag system electronic-control unit
Shutoff or shorting of wiring harness between clock spring and SRS safety airbag system electronic-control unit.
Misconnection of SRS safety airbag system driver’s side airbag generator connector clip

Procedure
