SITUATION
Compare the display to the "On-Board Computer II Coding Plug Table" shown below.
If the customer complains about an inaccurate range display reading check the reserve capacity calibration as follows:
- The low fuel level warning light on the fuel gauge must be illuminated (drain fuel from tank or pull level sensor from tank).
- Press the 1000 and 1 buttons at the same time.
- Compare the reading in the display to amount listed under reserve capacity for the appropriate model in the "On-Board Computer II Coding Plug Table"
- If the display is incorrect, remove the plastic plug located next to the 1000 button and adjust the reading by turning the potentiometer with a small screwdriver.
NOTE:
This procedure must always be performed after replacing an OBC II module.
