Current Too High. Intermittent Fault
Current too high. Intermittent fault
Mechanical check
Carry out the mechanical check according to Mechanical check Mechanical Check.
Was a fault found?
Yes - Fault-tracing information
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.
Other information:
- For the comment sheet, see Diagnostic list for convertible tops Diagnostic List For Convertible Tops
- For other values, see Opening and closing the convertible top Opening and Closing the Convertible Top
- To connect the breakout box, see Connecting the convertible control unit breakout box Connecting the Breakout Box.
Are these values correct?
Yes - Checking components and wiring
No - Calibrating the convertible system
-------------------------------------------------
Checking components and wiring
- Check control module connector D for an intermittent short-circuit to supply voltage according to Checking wiring and terminals. Intermittent faults Checking Wiring and Terminals. Intermittent Faults
- 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 an intermittent short-circuit to supply voltage according to Checking wiring and terminals. Intermittent faults Checking Wiring and Terminals. Intermittent Faults.
Remedy as necessary.

- To connect the breakout box, see Connecting the convertible control unit breakout box Connecting the Breakout Box
- To access and replace the control module see Replacing the control module Service and Repair.
Was a short-circuit found?
Yes - Fault-tracing information
No - Checking the engine
-------------------------------------------------
Checking the engine
- Check the relevant motor connector for an intermittent short-circuit to supply voltage according to Checking wiring and terminals. Intermittent faults Checking Wiring and Terminals. Intermittent Faults
- Ignition on.
Connect a voltmeter between the motor connector (red cable) and ground.
Check for an intermittent short-circuit to supply voltage according to Checking wiring and terminals. Intermittent faults Checking Wiring and Terminals. Intermittent Faults.
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.
Other information:
- To access and replace the relevant motor, see Replacing motors Service and Repair.
Was a fault found?
Yes - Fault-tracing information
No - No Fault Found
-------------------------------------------------
Calibrating the convertible system
It is important that the potentiometer values are calibrated and programmed into the control module if the potentiometer has been replaced. Carry out programming and calibration in VIDA.

Fault-tracing information
If the fault is intermittent, do not verify fault-tracing if the fault does not recur.
It is possible to view the information again, or leave fault-tracing for this diagnostic trouble code (DTC).
Do you want to view the information again?
Yes - Attempt New Test
No - FAULT FOUND
