Passengers’ side failure

Failure code

$9015
$9016
$9018
$9019

Passengers’ side safety airbag module (high or low resistance or shorting grounding)

Test condition

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
If with passengers’ side safety airbag failure
The resistance between SRS safety airbag system unit connector clip stitch 13 and stitch 14 not within the
designated scope.
The wiring harness shorting between safety airbag system unit stitch 13 and stitch 14
Open loop between SRS safety airbag system unit connector clip stitch 13 and stitch 14,

Possible causes

Passengers’ side safety airbag module failure
The failure of connector clip between passengers’ side safety airbag module and SRS safety airbag system
electronic-control unit
The failure of connector clip between SRS safety airbag system unit and grounding jumper.
The circuit shutoff or shorting between passengers’ side safety airbag module and SRS safety airbag system
electronic-control unit
The circuit shutoff or shorting between SRS safety airbag system unit and grounding jumper

The end of failure diagnosis

4

Check the wiring harness between passengers’ side safety airbag

module and SRS safety airbag system electronic-control unit

Place the ignition switch in LOCK position

Release accumulator negative wire and then wait for about 1

minute plus

Remove steering pillar shell

Release clock spring connector clip

Release driver’s and passengers’ side safety airbag module

connector clips

Release all SRS safety airbag system unit connector clips

Check whether the following troubles are with the circuit of the

connector clips terminals between SRS safety airbag system

electronic-control unit and passengers’ side safety airbag

module

Grounding

Power-supply shorting

Shutoff

Is the previous circuit normal?

Abnormal

Replace the relative wiring

harness

Impact-vehicle diagnosis

Test SRS-ECU diagnostic signals

1. Connect the (X-431 diagnostic test’s) diagnostic joint

2. Read the diagnostic results with X-431 diagnostic tester

Repairing procedure

1.When safety airbag is released.

The following parts should be replaced with new ones

a. Passengers’ side safety airbag module

b. SRS-ECU

c. Driver’s side safety airbag module

2 Check the following parts; replace them with new ones providing something wrong with them.

a. Clock spring

b. Steering-wheel, steering column, bottom steering shaft module

3.Driver’s side safety airbag module’s installation status towards the steering wheel.

a. Check whether abnormal knocking is with the steering wheel, its activity is in good condition and its clearance is normal.

b. Check whether the wiring harness joint is broken and its terminal is deformed.

Caution: Due to the impact, the diagnostic instrument cannot communicate with SRS-ECU when accumulator is lack of

power, in this case, check and maintain the instrument panel wiring harness or utilize the extension power supply.
