Attachment III - Technical Information
INSPECTION
1. Locate the speed control cable identification number. Read the second to last letter. See Figure 1.
^ If the letter is a "T", no service is required. Release the vehicle. If the letter is a "D", continue with this inspection.
2. Remove the snow/ice shield. See Figure 2.
3. Visually inspect the cable for any of the following unacceptable conditions (see Figure 3):
^ Cover flared or split.
^ Core wire exposed when no tension is applied to the cable.
^ Cable is kinked.
Replace the cable if any of the above conditions are found. For replacement and adjustment procedures, refer to Section 310-03, Vehicle Speed Control of the appropriate workshop manual.
If none of these conditions are found, continue with the next step of this procedure.
4. WARNING: BE SURE TO MARK THE STRAND COVER AT THE VERY POINT WHERE IT ENTERS THE NOTCHED CABLE HOUSING. FAILURE TO MARK THE COVER AND MEASURE THE DISTANCE ACCURATELY (AS OUTLINED IN STEP 6) MAY RESULT IN FAILURE TO REPLACE AN UNACCEPTABLE CABLE.
NOTE:
Use a suitable marker such as a fine point paint marker or a felt-tipped marking pen. Brush-on touchup paint may also be used. DO NOT use a blunt marker or one that has a worn-out tip. It could cause your measurement to be incorrect. Whichever marking device you decide to use, it must leave a clean, straight line at the very point where the strand cover enters the notched cable housing. You will be measuring, in very small increments, the distance from the very edge of the mark you make to a certain point on the cable assembly. THE MEASUREMENT MUST NOT INCLUDE THE THICKNESS OF THE MARK.
Clean the cable if necessary, then using a suitable marking device, mark the strand cover at the point where the cover enters the notched cable housing. See Figure 4.
5. Disconnect the speed control cable connector from the throttle body cam by pulling the connector upward. See Figure 4.
6. CAUTION: When performing the following check, you will be instructed to pull the connector taut. Use only your hand to pull the connector. DO NOT use any type of tool to do this or damage to the cable may occur.
CAUTION:
Do not grasp the cable so tightly that you will kink the cable.
NOTE:
When pulling the connector, the strand cover may or may not be pulled out of the notched cable housing. For the purpose of this inspection, either is acceptable.
NOTE:
The following check can be made using either the 4 mm checking gauge supplied to each dealership or a Vernier caliper (analog dial or electronic LCD display).
Pull the connector taut (toward the front of the vehicle). See Figure 5.
A) If the strand cover does not pull out of the notched cable housing, no further service is required. Reattach the connector to the throttle body cam, install the snow/ice shield and release the vehicle.
B) If the strand cover is pulled out of the notched cable housing, using either the supplied 4 mm checking gauge or a Vernier caliper, measure the distance from the inside edge of the mark to the end of the exposed strand cover. Do not include the thickness of the mark when taking the measurement. See Figures 5 and 6.
^ If the measurement is 4 mm (5/32-inch or 0.157-inch) or greater, no further service is required. Reattach the connector to the throttle body cam, install the snow/ice shield and release the vehicle.
^ If the measurement is less than 4 mm (5/32-inch or 0.157-inch), the speed control cable must be replaced. For replacement and adjustment procedures, refer to Section 310-03, Vehicle Speed Control of the appropriate workshop manual.
