Seat Belt Pretensioner ^?
060C Warning Lamp Short Circuit
060C will be logged if the nnonitor current flow
through the SRS/Airbag warning lamp is excessive.
The warning lamp circuit is normally at 12 volts and
is switched to ground by the airbag control module
or by the pretensioner control module when one of
these control modules detects a fault.
If either control module connector is displaced and
the ignition is switched on, the warning lamp will
be illuminated via the ground shorting link between

pins!
and 2 ofthe pretensioner controller connector
or pins 4 and 5 of the airbag controller connector,
both control modules must be checked for the
appropriate DTC to isolate which circuit is at fault.
Procedure

1.
Connect the PDU to the lower diagnostic socket
and access the pretensioner control module. Verify
that an 060C code is logged and note if the fault is
shown as intermittent. Note any other codes in the
DTC log and then clear all codes. Go to step 2.
If fault code 060C is not logged, go to the diagnostics
section of the airbag system.

2.
Check the security of the pretensioner control
module connector.
If the connector is secure, go to step 3.
If the connector isdisplaced,resecu re theconnector.
Clear all logged DTCs and retest the vehicle to
ensure that the problem is resolved.
3. Access the SRS/Airbag warning lamp and check the
lamp resistance.
If the resistance is approximately
120£2,
the lamp is

good.
Refit the lamp and go to step 4.
If the resistance of the lamp is significantly less than
approximately 120^, fit a new lamp and refit the
instrument panel. Clear the logged DTCs from the
pretensioner control module and retest the vehicle
to ensure that the problem is resolved.

4.
If the checks in step 3 are good, the low circuit
resistance must be in the instrument pack or in the
control module. Replace the pretensioner control
module and reconnect all components.
6. Switch on the ignition and then test the vehicle.
If the 060C code is logged again, replace the
instrument pack.
060D Warning lamp open circuit
060D will be logged if the monitor current flow
through the SRS/Airbag warning lamp is below the
normal monitor level.
The warning lampcircuit is normally at 12 voltsand
is switched to ground by the airbag control module
or by the pretensioner control module when one of
these control modules detects a fault.
Procedure
Connect the PDU to the lower diagnostic socket
and access the pretensioner control module. Verify
that an 060D code is logged and note if the fault is
shown as intermittent. Note any other codes in the
DTC log and then clear all codes. Go to step 2.
lffaultcode060D is not
logged,
gotothediagnostics
section of the airbag system.
Switch off the ignition. Access the SRS/Airbag
warning lamp and check the lamp resistance. The
resistance should be approximately 120Q.
If the resistance is 120i2, go to step 3.
If the lamp resistance is significantly lower than

120^2,
replace the lamp. Retest the vehicle to
ensure that the problem is resolved.
Wait 10 minutes after switching off the ignition to
ensure that the pretensioner firing capacitors have
fully discharged.
Disconnect the pretensioner control module and
temporarily cheat the warning lamp shorting link.
Note: The control module harness connector has a
shorting link which short circuits the warning lamp line
(pin 2)to ground
(pin
Dwhen
the
connector
is
displaced.
Carefully insert a suitable non-metallic cheater to remove
the
short
circuit
between
pins
1
and 2 before continuing
with fault
diagnosis.
