Read Measurement & Read Measuring (Test) Value Block

NOTE: See ENTERING SELF-DIAGNOSTICS for additional scan tool operating instructions.

Ensure battery voltage and fuse No. 22 are okay. Ensure engine ground connections at cylinder head cover and manifold are okay.
Data Link Connector (DLC) is located below tachometer. See Figure . Remove DLC cover. Ensure ignition is off. Connect scan tool to DLC. Scan tool should alternately display 1-RAPID DATA TRANSFER and 2-BLINK CODE OUTPUT.
Turn ignition on, or start engine, depending on function being selected. See SELECTABLE FUNCTIONS table under ENTERING SELF-DIAGNOSTICS. Press "1" button to select RAPID DATA TRANSFER function.
Press "0" and "8" buttons to select READ MEASURING VALUE BLOCK function. Press "Q" button to enter input. READ MEASURING VALUE BLOCK will be displayed on scan tool.
Press "00" to "17" buttons to select desired display group. See the DISPLAY GROUP TABLE . When display group "00" is selected, only READ MEASUREMENT BLOCK is shown on display (the zeros do not appear on display). When READ MEASUREMENT BLOCK function is completed, select END DATA TRANSFER function on scan tool. Turn ignition off. Disconnect scan tool.
