Question

Does the car have a DSTC system?

Yes - DSTC

No - STC

Checking diagnostic trouble codes (DTCs)

Note! If diagnostic trouble codes (DTC) ABS-0072 and ABS-0075 are stored as permanent faults at the same time the control module must be replaced.




- Ignition on
- Click on the VCT2000 symbol to read off the diagnostic trouble codes (DTCs).
IfbothABS-0072 and ABS-0075 are stored as permanent faults the ABS control module must be replaced.

Other information:
- To replace the control module, see Control module (ABS), replacing Brake Control Module (BCM), Replacing.





Were diagnostic trouble codes (DTC) ABS-0072 and ABS-0075 stored as permanent faults?

Yes - Fault Found

No - Checking fuse 11

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

Checking fuse 11
- Check that fuse 11 in the integrated relay / fusebox in the engine compartment is intact.
If the fuse is blown check the cable between fuse 11 and control module terminal #9. Check for a short-circuit to ground. See Checking wiring and terminals. Permanent fault Checking Wiring and Terminals. Permanent Fault. Then replace the fuse.
Remedy as necessary.

Other information:
- To connect the breakout box, see Connecting the ABS breakout box Pinout Values and Diagnostic Parameters.













Was the fuse OK?

Yes - Checking the 30-supply to the control module

No - Verification

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

Checking the 30-supply to the control module








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









The voltmeter should read battery voltage.

OK - Checking the control module

Not OK - Checking the voltage before the fuse 11

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

Checking the voltage before the fuse 11
- Connect a voltmeter between the left socket on the fuse holder for fuse 11 and ground.
The voltmeter should read battery voltage.
If the voltmeter reads 0 V, it indicates that there is an open-circuit in the cable between fuse 11 and the battery. Check the cable. Check for an open-circuit. See Checking wiring and terminals. Permanent fault Checking Wiring and Terminals. Permanent Fault.
Remedy as necessary.









Select Continue when the fault has been remedied.

Continue - Verification

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

Checking the control module








- Ignition off
- Disconnect the breakout box
- Connect the control module.
- Test drive the car. See Test Drive Form (ABS), description Test Drive Form (ABS), Description
- Ignition on.
Read off the status of the diagnostic trouble code (DTC).









Is the status INTERMITTENT?

Yes - Checking for contact resistance and oxidation

No - Replacing the component

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

Checking for contact resistance and oxidation
The cause of the fault was loose connections in the control module connector.
Check the control module connectors. Check for contact resistance and oxidation. Remedy if necessary. See Checking wiring and terminals. Permanent fault Checking Wiring and Terminals. Permanent Fault.





Select Continue when the fault has been remedied.

Continue - Fault Found

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

Replacing the component
Try a new control module. See Control module (ABS), replacing Brake Control Module (BCM), Replacing.
