Failure to do so could damage the module. When testing voltage or continuity at any control module, use the terminal side (not the wire end) of Be careful when performing electrical tests so as to prevent accidental shorting of terminals. Such When replacing a blown fuse, it is important to use only a fuse having the correct amperage rating. may result in a dangerous electrical system over- 4.3.2 ROAD TESTING A COMPLAINT Some complaints will require a test drive as part of the repair verification procedure. The purpose of CAUTION: Before road testing a vehicle, be T screen while in motion. Do not hang the DRBIII T from the rear view mirror or operate it yourself. Have an assistant available to operate the DRBIII T . Road testing is an essential step in the diagnostic process that must not be overlooked. Along with the t Scan Tool and the original customer concern, the Just as important as the road test is, there are preliminary inspections that should be performed Some of the conditions of incorrect fluid level are as follows: • Delayed engagement • Poor shifting or erratic shifting • Excessive noise • Overheating The next step is to verify that the shift linkage is correctly adjusted. If the shifter is incorrectly ad- The control module monitors the Shift Lever Position (SLP) Sensor continuously. If the shifter is The following complaints may also be the result of an incorrectly adjusted shifter: • Delayed clutch engagement • Erratic shifts 7 GENERAL INFORMATION |
