Was a fault found?
Yes - Verification
No - Checking the values
-------------------------------------------------
Checking the values
- Ignition on
- Connect the Volvo Scan Tool (ST).
Read off the program status of the convertible top. Check the values at the relevant step.

Are these values correct?
Yes - Checking components and wiring
No - Replacing the potentiometer
-------------------------------------------------
Checking components and wiring
- Check control module connector D. Check for a short-circuit to supply voltage. See Checking wiring and terminals. Permanent fault Checking Wiring and Terminals. Permanent Fault
- Disconnect the control module.
- Ignition on.
Connect a voltmeter in order between:
D6 and ground, motor, convertible top, right-hand side.
D11 and ground, motor, convertible top, left-hand side.
Check for a short-circuit to supply voltage according to Checking wiring and terminals. Permanent fault Checking Wiring and Terminals. Permanent Fault.
Replace the control module if a short-circuit is found.

Was a fault found?
Yes - Verification
No - Checking the engine
-------------------------------------------------
Checking the engine
- Check the relevant motor connector for a short-circuit to supply voltage according to Checking wiring and terminals. Permanent fault Checking Wiring and Terminals. Permanent Fault
- Ignition on.
Connect a voltmeter between the motor connector (red cable) and ground.
Check for a short-circuit to supply voltage according to Checking wiring and terminals. Permanent fault Checking Wiring and Terminals. Permanent Fault.
Replace the motor if there is a short-circuit in the motor.
If no fault is found there is probably a short-circuit in the cable between the control module and the motor connectors.
Remedy as necessary.
