Short-circuit to ground

Checking diagnostic trouble code (DTC) and type of fault

Hint: Before starting to remove components, the Volvo Scan Tool (ST) should be used to check whether the fault is permanent or intermittent.




Clear diagnostic trouble code (DTC).

- Wait at least 10 seconds.
Read off diagnostic trouble code (DTC).
It should not be possible to clear diagnostic trouble code (DTC) SRS-223 if the fault is permanent.





Can the DTC be erased?

Yes - Diagnostic trouble code (DTC) SRS 223 could be cleared

No - Disconnecting connector from passenger module

-------------------------------------------------

Checking DTCs with the passenger module replaced by special tool 998 8695








- Connect special tool 998 8695 TEST DEVICE 998 8695 Test Device to SRS ignition cable igniter connector.

Caution! The special tool should be checked and defect free. If the tool is defective it will cause errors in the diagnosis and make fault tracing harder.

- Ignition on.
- Connect battery negative lead.
Clear diagnostic trouble code (DTC).









Continue - Checking DTCs with the steering wheel module replaced by special tool 998 8695, continuation

-------------------------------------------------

- Ignition on.
- Connect battery negative lead.
- Wait at least 10 seconds.
Read off diagnostic trouble code (DTC).
If the fault is in the passenger module diagnostic trouble code (DTC) SRS-223 should be stored.





Is the diagnostic trouble code (DTC) displayed?

Yes - Replacing component

No - Disconnecting connector from passenger module

-------------------------------------------------

Replacing component
There is a short circuit in the passenger module.
- Replace passenger module in accordance with Passenger module, replacement Passenger Module, Replacement.





Select continue when the defect has been remedied.

- Ignition off.
- Disconnect battery negative lead.
- Remove special tool 998 8695 TEST DEVICE 998 8695 Test Device.




- Separate connector 24/33 on SRS ignition cable.
- Remove SRS ignition cable.
- Check that SRS ignition cable sleeve is in good condition (for a short circuit to ground).

Is the ignition cable damaged?

Yes - Replacing component

No - Checking for short circuit to ground in SRS ignition cable in SRS cable harness and the sensor module

-------------------------------------------------

Replacing component
- Replace passenger module SRS ignition cable in accordance with Passenger module, replacement Passenger Module, Replacement.

Select continue when the defect has been remedied.

Continue - FAULT FOUND

-------------------------------------------------

Checking for short circuit to ground in SRS ignition cable in SRS cable harness and the sensor module




- Ignition off.
Connect an ohmmeter between a good ground terminal and the connection sockets in the SRS sensor module half of connector 24/33 (part B in the figure).

Caution! Take care not to damage connector pins.




- Connect one ohmmeter test terminal to ground.
- Take an ohmmeter reading with the other test terminal against the female connector half terminal 1.
- Then take an ohmmeter reading against female connector half terminal 2.
- The ohmmeter should show 72 kohms at the first reading. At the second reading, approx. 25 kohms with FLUKE or 16 kohms with VIDA.

Are these values OK?

OK - Replacing component

Not OK - Checking for short circuit to ground in SRS ignition cable in the SRS cable harness

-------------------------------------------------

Replacing component
SRS ignition cable in the SRS cable harness between connector 24/33 and the sensor module is OK.
- Replace passenger module SRS ignition cable in accordance with Passenger module, replacement Passenger Module, Replacement.

-------------------------------------------------

Checking for short circuit to ground in SRS ignition cable in the SRS cable harness








- Ignition off.
- Expose and remove the SRS sensor module connector according to: Replacing the SRS sensor module Service and Repair

Caution! Never touch the sensor module pins. There is a risk of static discharge which could damage the sensor module.

Connect an ohmmeter between a good ground terminal and the connection sockets in the SRS sensor module half of connector 24/33 (part B in the figure).

Caution! Take care not to damage connecting sockets.




- Connect one ohmmeter test terminal to ground.
- Take an ohmmeter reading with the other test terminal against the female connector half terminal 1. The ohmmeter should read infinite resistance.
