There are no service parts available for the LCD Oil Temperature/ Level Dipstick. However, a replacement CR 2032 battery (Part Number 66373-06) is available from a Harley-Davidson dealer.
LCD READOUT DIPSTICK INSTALLATION
- Remove the original equipment (OE) dipstick from the filler neck.
- See Figure 3. Lightly oil the rubber grommet (1) on the new LCD dipstick. Orient the dipstick so that the display window is horizontal and readable from left to right, with the Bar and Shield logo to the left (toward the rear of the vehicle). Push the dipstick straight into the filler neck until it seats.
NOTE
Following installation, check for proper seating by gently lifting up on the dipstick display body. The dipstick should be locked in place.
LCD READOUT DIPSTICK USE AND CARE
Removing the Dipstick
The dipstick assembly must be removed from the filler neck to add oil or to service the internal battery.
Displaying the Oil Temperature and Level
See Figure 1. Press and release the rubber button on the front face to display the temperature of the oil in the oil tank in degrees Fahrenheit (°F), and the oil level. The display will automatically shut off after 10 seconds.
NOTICE
Do not overfill oil. Doing so can result in oil carryover to the air cleaner leading to equipment damage and/or equipment malfunction. (00190b)
NOTE
Oil level cannot be accurately measured on a cold engine.
Oil level cannot be accurately measured with the engine running.
Oil level on 2000 through 2004 Softail models with the OE dipstick is checked with the motorcycle standing upright (not leaning on the jiffy stand). THIS IS NOT THE CASE with the LCD Oil Temperature/ Level Dipstick. For ALL 2000 and later Softail models, oil level inspection MUST be done with the motorcycle LEANING
ON the jiffy stand, on level ground.
For pre-ride oil level inspection:
With the motorcycle LEANING ON the jiffy stand, on level ground,
- the oil level should be as indicated in Figure 1 , display 4 through 8 (bars showing oil level, and "COLD OIL" message followed by flashing oil temperature) when the engine is cold.
- If the oil level indicates as shown in display 9 (animated level bars, and "Error" message followed by flashing oil temperature), refer to OIL LEVEL COLD CHECK in your Owner's Manual for proper oil fill of a cold engine. DO NOT ADD OIL to bring the level to the FULL mark on the dipstick of a COLD engine.
For oil level inspection at operating temperature: Ride the motorcycle until the engine is at normal operating temperature.
With the motorcycle standing upright (NOT leaning on the jiffy
stand), on level ground, allow the engine to idle for one to two minutes.
Turn the engine OFF, then rest the motorcycle on the jiffy stand, on level ground.
- Bubbles in the oil may cause inaccurate readings. Wait two minutes for the oil to settle and any bubbles to come to the surface.
- Press and release the rubber button on the front face of the LCD Oil Temperature/ Level Dipstick to display the temperature and level of the oil in the oil tank. The oil level should be as indicated in Figure 1 , display 11, 12, 13 or 14.
- If the oil level indicates as shown in display 10, 15 or 16, refer to OIL LEVEL HOT CHECK in your Owner's Manual for proper oil fill procedure.
Changing the Display Mode
The display can be changed to read in degrees Centigrade (°C) by pressing and holding the button in for approximately 5 seconds, then releasing the button. From then on, pressing and releasing the button will display the temperature in "°C".
Change back to "°F" display in the same way.
Extended Temperature/ Level Display
Press the button twice in rapid sequence to have the display remain on for an extended time. The display will automatically shut off after about 5 minutes. To manually shut off the display sooner, press the button once.

Display Errors
An "888" error code will display to indicate a disconnected or broken wire.
When the power level of the Dipstick battery falls below 2.5V the blue LED back light is disabled, and the battery symbol (see Figure 2 ) will begin to flash.
NOTE
Oil level sensor accuracy is reduced above 275° F (135° C). Oil level reading errors may occur when measuring oil at temperatures above 275° F (135° C).

Cleaning the Dipstick Micro Screen
The dipstick oil level sensor requires oil to pass through the micro screen into the dipstick. To reduce measurement errors, periodically clean the micro screen.
Replacing the Battery
The LCD oil temperature display is powered by a long lasting, replaceable CR 2032 Lithium battery. When battery replacement is needed, only a CR 2032 battery should be used.
A replacement CR 2032 battery (Part Number 66373-06) is available from a Harley-Davidson dealer.
NOTE
These batteries are also widely available at local battery outlets.
NOTICE
Read the following instructions and make sure you fully understand them prior to replacing the battery. If the procedure is not within your capabilities, or you do not have the correct tool, have a Harley-Davidson dealer replace the battery. Improper installation could result in damage to this product. (00419b)
NOTE
When separating the rubber grommet (1) from the black plastic collar (5) on the display body assembly (4), be extremely careful not to disconnect or damage the internal wires.
- See Figure 3. Carefully peel back the lip (2) around the edge of the rubber grommet to separate the grommet and dipstick (3) from the display body collar.
- While being extremely careful not to strain the wiring, gently separate the display and dipstick assemblies.
- Note the battery orientation. Using a mechanics pick or a small screwdriver, carefully insert the tool under the battery (7) in the area (8) opposite the retaining tabs (9). Gently pry the battery free. Discard the battery. Insert the new battery under the retaining tabs as shown and push the battery down until seated.
- Lining up the tab (6) on the display body collar with the notch inside the rubber grommet, assemble the two parts, being careful not to pinch the wiring.
- Insert the dipstick into the filler neck. See LCD READOUT DIPSTICK INSTALLATION.
- Check for proper operation by pressing the rubber button on the front face. See LCD READOUT DIPSTICK USE AND CARE.

Nature of the Liquid Crystal Display (LCD)
Due to the nature of an LCD, the readout will not display the oil temperature properly when the display body is exposed to extreme temperatures caused by heat transfer from the transmission case or oil tank. Typically this will happen only with the TC88 powertrain.
These extremes can occur in stop and go traffic and/or parade duty combined with a high ambient (outside air) temperature. If this situation occurs, DO NOT be alarmed. The LCD will not be damaged, and will function properly when the LCD has returned to a normal operating temperature.
Note also that, after prolonged exposure to direct bright sunlight, some or all of the LCD segments may become visible, causing the LCD to appear to be reading improperly without the rubber button having been pressed. This can be overcome by shading the display until the face temperature cools enough to achieve a proper reading.
