Checking motors and wiring
- Ignition off
- Check control module connector D for contact resistance and oxidation according to Checking wiring and terminals. Permanent fault Checking Wiring and Terminals. Permanent Fault
Connect an ohmmeter in order between:
D1 and D7, motor, front lock.
D2 and D8, motor, cover plate lock.
D3 and D9, motor, tension bow, left-hand side.
D4 and D10, motor, tension bow, right-hand side.
D5 and D11, motor, convertible top, left-hand side.
D6 and D12, motor, convertible top, right-hand side.
D13 and D14, motor, rear latch arms.
Check the motors and cables for an open-circuit according to Checking wiring and terminals. Permanent fault Checking Wiring and Terminals. Permanent Fault.
Disconnect the relevant motor if an open-circuit is found.
Check the motor connector. Check for contact resistance and oxidation according to Checking wiring and terminals. Permanent fault Checking Wiring and Terminals. Permanent Fault.
Connect an ohmmeter to the motor between 1 and 2. Check for an open-circuit according to Checking wiring and terminals. Permanent fault Checking Wiring and Terminals. Permanent Fault.
Replace the motor if an open-circuit is found.
If there is no open-circuit in the motor the fault is in the cable between the control module and the motor.
Remedy as necessary.

- Check control module connector D. Check for a short-circuit to ground according to Checking wiring and terminals. Permanent fault Checking Wiring and Terminals. Permanent Fault.
Connect an ohmmeter in order between:
D1 and ground, motor, front lock.
D7 and ground, motor, front lock.
D2 and ground, motor, front lock.
D8 and ground, motor, front lock.
D3 and ground, motor, tension bow, left-hand side.
D9 and ground, motor, tension bow, left-hand side.
D4 and ground, motor, tension bow, right-hand side.
D10 and ground, motor, tension bow, right-hand side.
D5 and ground, motor, convertible top, left-hand side.
D11 and ground, motor, convertible top, left-hand side.
D6 and ground, motor, convertible top, right-hand side.

Test for a short-circuit to ground according to Checking wiring and terminals. Permanent fault Checking Wiring and Terminals. Permanent Fault.
If a short-circuit is found, check the relevant motor connector for a short-circuit to ground according to Checking wiring and terminals. Permanent fault Checking Wiring and Terminals. Permanent Fault.
Connect an ohmmeter between 1 and ground and 2 and ground on the relevant motor. Check for a short-circuit to ground according to Checking wiring and terminals. Permanent fault Checking Wiring and Terminals. Permanent Fault.
Replace the motor if a short-circuit is found.
If there is no short-circuit to ground in the motor, there is probably a fault in the cable between the control module and the motor.
Remedy as necessary.

Hint: After the repair it is necessary to check that the fault has been rectified.
- Ignition off
- Connect the connectors, install the components, etc.
- Ignition on
- Apply parking brake
- Close the luggage compartment lid
- Speed < 4km/h.
Operate the control switch to move the convertible top.
Move the convertible top to its end positions.
