Before balancing the inhibitor switch, make sure that the selector cable is properly adjusted. In the engine compartment, remove the battery hold down clamp, and as a helper raises the battery a little with the terminals attached, take out the tray underneath the battery. Disconnect the wiring of the inhibitor switch, and, connecting an ohmmeter between the terminals 9 and 10 of the inhibitor switch, measure continuity, which at no point should occur except when the selector lever is in the Neutral or Park position. As required, use Neutral, loosen the retaining bolts and position the inhibitor switch until a 6 mm drill bit can be inserted on the inhibitor switch boss and into the hole in the lever of selection; should the adjustment fail to correct the fault, change the inhibitor switch. Moving the selector lever to Reverse, verify continuity between the inhibitor switch terminals 7 and 8, and when the inhibitor switch is not in Reverse, continuity is checked to ensure that there is none; in case of fault, replace the inhibitor switch. To take the inhibitor switch off, once more lift the battery hold down clamp and have an assistant slightly raise the battery then lift the tray. Pull the clip that holds the inner selector cable off the selector lever, and pull the inner cable off the pin. Take the nut and washer off the selector shaft and pull the selector lever out of the transaxle. Indicate the installed position of the inhibitor switch inside the assembly and take out the retaining bolts and pull out the inhibitor switch out of the transaxle. To install, simply reverse the removal process, making sure to keep the inhibitor switch in the identified position when tightening the retaining bolts to a certain torque. Install washer, nut and the selection lever, ensuring that the nut of the selection shaft is firmly fixed and ensures that there is no fault in the functioning of the inhibitor switch, and it may be necessary to adjust the lever.
