Check gear mechanism adjustment
NOTE: Illustration shows earlier version. Reaction strut is not installed on later version.
- Check and adjust fluid level.
NOTE: The gear box must be filled with ATF fluid that complies with the specifications for both Dexron II E and Ford Mercon alternatively Dexron III and Ford Mercon.
CAUTION: Since fluid and transmission are both cold, and engine is switched off, correct fluid level will be only a few mm on the dipstick.
NOTE: (Fluid temperature in transmission may be checked with Volvo ST in test mode 5 - code 1-1-5.)
- Reconnect battery ground lead
- Erase DTCs, if any, in OBD memory.
- Switch on ignition.
- Connect DLC test lead to socket No.1.
- Press DLC test button for more than 5 seconds. Release button.
- LED should light after 3 seconds.
- Press button again for more than 5 seconds.
- Release button. LED should go out.
- Check that DTCs are erased by pressing test button once for more than 1 second (but not more than 3 seconds).
- If code 1-1-1 is displayed, DTCs are erased.
Test drive car in all three driving modes
- Check fluid level when transmission has reached working temperature.
- Gear selector should be in position P with engine idling.
