Signal Too Low

Signal too low

Status check




- Ignition off.
- Disconnect the Volvo Scan Tool (ST) from the VIDA station. Use it in stand alone mode and connect it to the data link connector (DLC) in the car.
- Ignition on.
- Read off diagnostic trouble code (DTC) counter and make a note of the value.





Is counter value greater than 0?

Yes - Faulty signal. Intermittent fault

No - Checking for a short-circuit to ground

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

Checking for a short-circuit to ground
On cars with ECC: Check cable between combined instrument panel #A6 and ECC control module #C1 for a short-circuit to ground according to Checking wiring and terminals. Permanent fault Checking Wiring and Terminals. Permanent Fault.










Continue - Verification

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

Verification

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












- Ignition off.
- Reinstall connectors, components etc.
- Test drive the car at speeds above 20 kph, alternatively lift up the front suspension safely and remove both front wheels.

Warning! Cars with AWD, test drive the car at speeds higher than 20 kph, alternatively lift up the front and rear suspension safely and remove all wheels.

Note! When the rear wheels are stationary and the front wheels rotate, diagnostic trouble codes (DTCs) may be stored in the ABS system. Erase any diagnostic trouble codes (DTCs) stored in the ABS system after fault-tracing.

Note! Ensure that the front wheels are not rotating when the gear selector is moved.

- Ignition off.
- Disconnect the Volvo Scan Tool (ST) from the VIDA station. Use it as a stand alone tool and connect it to the data link connector (DLC) in the car.
- Ignition on.
