  Q: How should a Transmission Control Module be fitted and programmed on Volvo V50?

  A:

  If a new control module is fitted, it has to be programmed on dedicated Volvo test equipment so it is advisable to trust this task to a Volvo dealer or suitably-equipped specialist. To start the removal, turn off the ignition and wait at least 2 minutes before disconnecting the battery negative lead to make sure that any remaining electrical energy has dissipated. If the cooling fan keeps on running even after turning off the ignition, wait until the fan stops and then wait for another minute before removing the battery lead. Next, remove the air cleaner assembly. The Transmission Control Module (TCM): Located on the top of the transmission casing, disconnect the wiring plugs from the TCM (take care to avoid touching the control module terminal pins with the bare hands to cause damage to the component from static electricity). Undo the retaining bracket screw and remove the bracket to the right hand side of TCM. For models whose transmission is TF-80SC, undo the 2 bolts and take off the cable guide next to the TCM. Then, undo 3 retaining bolts and lever retaining nut, pull the lever off the spindle and remove the TCM. For refitting, make sure to place the gear selector in the neutral position and also make sure that you locate the TCM in position while ensuring that the arrows on the lever spindle and the TCM casing match their position and refit the TCM retaining bolts and the retaining bracket, and make sure to tighten it securely. Refit the lever and tighten the retaining nut securely, refit the wiring plugs and refit the air cleaner assembly. At the last, reconnect the negative lead of the battery.
