General Troubleshooting 4-35Check Drive MenuWiper DriveThis test moves the wiper drive mechanism through the complete range of its motion in eachdirection and does an “on-the-fly” reversal to verify operability.R# DefinitionTypicalValue Actions0 Up Motion DriveError (uin)120 to275Reports the average following error while movethe wiper up from the low limit to the lockencounter point.1 Up Motion DriveError Ripple (uin)35 to 150 Reports the difference between the max andmin following error over the same interval.2 Up Distance (uin) 3200 to4600Reports the difference between the max andmin limits of travel when moving up.3 Lock EncounterDistance (uin)3054 to5115Reports the distance up from the lower limit oftravel at which the head lock latch isencountered.4 Lock EngageDistance (uin)3080 to5153Reports the distance up from the lower limit oftravel at which the head lock latch engages.5 Lock Engage Peak(uin)-1570 to2083Reports the peak following error at the pointthe latch engages.6 Down Motion DriveError (uin)MFGOnlyReports the average following error while movethe wiper up from the low limit to the lockencounter point.7 Down Motion DriveError Ripple (uin)MFGOnlyReports the difference between the max andmin following error over the same interval.8 Down Distance (uin) 3200 to4600Reports the difference between the max andmin limits of travel when moving up.9 Lock DisengageDistance (uin)-2000 to0Reports the distance up from the upper stallpoint at which the head lock latch releases.10 Lock DisengagePeak (uin)-800 to-150Reports the peak following error at the pointthe latch releases.11 Bottom EncounterDistance (uin)-5000 to1000Reports the distance up from the upper limit oftravel at which the wiper first encounters thelower travel limit.12 TurnaroundRecovery time (sec)0.001 to0.25Reports the time following the start of theturnaround motion that the motion drive errorreturn to normal in the opposite direction.
