Checking the Communication Cable

Since the ABS system communication is not working either this indicates that there is a fault on the circuit between the connected control modules in the circuit and data link connector (DLC).

Check cable between data link connector (DLC) terminal 7 and the connected control modules for an open-circuit according to Open-Circuit, Permanent Faults , short-circuit to supply voltage according to Short-Circuit To Supply Voltage. Permanent Faults , and for a short-circuit to ground according to Short-Circuit To Ground, Permanent Faults .

Check data link connector (DLC) connector for contact resistance and oxidation according to Contact Resistance And Oxidation .

HINT: For further information about the circuit to data link connector (DLC), see appropriate Service Information Wiring Diagram. 

If no faults are detected, Check Volvo Scan Tool (ST) according to Service Information Volvo Scan Tool (ST)

Remedy as necessary.

Other information: 

• Connection of breakout box to ECC control module, refer to Connection Of Breakout Box ECC .
• Voltage on communication cable should be approximately 9-11 V with ignition on. If the Volvo Scan Tool (ST) is connected these values do not apply. For other signals, refer to Signal Specification ECC .
