Permanent Fault






Permanent fault

Identifying control module version
Different fault-tracing procedures are carried out depending on the control module version. Read off the code in the bottom left hand corner of the control module product plate.





Does the code start with *M5.* or *P1.*?

Yes - Connecting breakout box and checking ground terminals

No - Replacing component

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

Connecting breakout box and checking ground terminals





Connecting the breakout box

Connecting the breakout box




- Ignition off.
- Disconnect the ABS control module by pressing in the catch on the rear edge of the cover (wheel arch side). Carefully turn the cover upwards so that the locking catches release.
- Check control module and control module connector to ensure that: Male and female terminals are undamaged and properly attached (cannot be pressed in). Female terminal cables are correctly connected to the terminals.
- Pay particular attention to the terminals related to the diagnostic trouble code (DTC)/symptom.
- Connect adapter 951 1354 Adapter 25-pin ABS 850 951 1354 Adapter 25-Pin ABS 850 to the control module connector (wiring side) and connect breakout box 951 1428 Breakout box 951 1428 Breakout Box to the adapter.
- Control module disconnected.
- Then check ground terminals.





Continue - Checking ground terminals

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

Checking ground terminals








- Ignition off.
- Switch off all equipment that takes power from the battery (courtesy lighting, radio etc).




- Connect an ohmmeter between battery negative terminal and #8 and #24 on the breakout box.

The ohmmeter should read approximately 0 ohms for all readings.

OK - Return to the fault-tracing procedure where it was interrupted.
Reading is OK

Not OK - Check ground terminal 1/1 (battery negative terminal) and cable between ground terminal and control module #8 and #24, for an open-circuit and contact resistance.-Return to the fault-tracing procedure where it was interrupted.
Value is not OK

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

Reading is OK
- Return to the fault-tracing procedure where it was interrupted.

Continue - FAULT FOUND

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

Value is not OK
- Check ground terminal 1/1 (battery negative terminal) and cable between ground terminal and control module #8 and #24, for an open-circuit and contact resistance.
- Return to the fault-tracing procedure where it was interrupted.

Continue - FAULT FOUND

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


FAULT FOUND - Checking 30-supply to control module

FAULT-TRACING FAILED - Checking 30-supply to control module

No Fault Found - Checking 30-supply to control module

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

Checking 30-supply to control module








- Ignition off.
- Control module disconnected.
Connect a voltmeter between #8 and #9 on the breakout box.









The voltmeter should read battery voltage.

OK - Checking the control module

Not OK - Checking fuse

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

Checking fuse
Check that fuse 11/14 is intact. (For the 850 diesel fuse 11A/4).





Is the fuse intact?

Yes - Checking voltage before fuse 11/14

No - Checking for a short-circuit and replacing component

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

Checking for a short-circuit and replacing component
Check cable between fuse 11/14 and control module #9 for a short-circuit to ground according to Checking wiring and terminals. Permanent fault Checking Wiring and Terminals. Permanent Fault.
(For the 850 diesel, check cable between fuse 11A/4 and control module #9 and fuse 11A/4 and #25 for a short-circuit to ground according to Checking wiring and terminals. Permanent fault Checking Wiring and Terminals. Permanent Fault.
Then replace the fuse.









Select Continue when the fault has been remedied.

Continue - Verification

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

Checking voltage before fuse 11/14
Connect a voltmeter between the rear socket of the fuse holder for fuse 11/14 and ground. (For the 850 diesel the pin in fuse 11A/4).





The voltmeter should read battery voltage.

OK - Checking for an open-circuit in the cable

Not OK - Checking for an open-circuit in the cable

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

Checking for an open-circuit in the cable
Check cable between fuse 11/14 and control module #9 for an open-circuit according to Checking wiring and terminals. Permanent fault Checking Wiring and Terminals. Permanent Fault. (For the 850 diesel fuse 11A/4).









Select Continue when the fault has been remedied.

Continue - Verification

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

Checking for an open-circuit in the cable
Check cable between fuse 11/14 and battery for an open-circuit according to Checking wiring and terminals. Permanent fault Checking Wiring and Terminals. Permanent Fault. (For the 850 diesel fuse 11A/4).









Select Continue when the fault has been remedied.

Continue - Verification

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

Checking the control module








- Ignition off.
- Disconnect breakout box.
- Connect control module.
- Disconnect the Volvo Scan Tool (ST) to interrupt diagnostics.

Warning! The ABS and EBD functions are not available when Volvo Diagnostics are activated. Take care when test driving the car as the wheels may lock when braking.

Test drive car according to Test driving Test Driving.





Read off the diagnostic trouble code (DTC) status. Is the status INTERMITTENT?

Yes - Checking for contact resistance and oxidation

No - Replacing component

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

Checking for contact resistance and oxidation
The cause of the diagnostic trouble code (DTC) was loose connections in the control module connector.
Check control module connector for contact resistance and oxidation and remedy according to Checking wiring and terminals. Permanent fault Checking Wiring and Terminals. Permanent Fault.

Select Continue when the fault has been remedied.

Continue - FAULT FOUND

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

Replacing component
Try a new control module according to Replacing the control module Removal and Replacement.

Select Continue when the fault has been remedied.

Continue - Verification

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

Verification

Hint: After carrying out the repair check that the fault has been remedied.




- Ignition off.
- Reinstall connectors, components etc.
Disconnect the Volvo Scan Tool (ST) to interrupt diagnostics.

Warning! The ABS and EBD functions are not available when Volvo Diagnostics are activated. Take care when test driving the car as the wheels may lock when braking.

Test drive car according to Test driving Test Driving.





Read off the diagnostic trouble code (DTC) status. Is the status INTERMITTENT?

Yes - FAULT FOUND

No - Fault-tracing information

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

Fault-tracing information




Information

Fault-tracing information
The fault should have been detected and remedied. As this is not the case fault-tracing has failed.
Exit fault-tracing for this diagnostic trouble code (DTC) or make another attempt.

Do you want to exit fault-tracing?

Yes - Exit fault-tracing

No - Attempt New Test

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

Attempt New Test - Connecting breakout box and checking ground terminals
