EFI Diagnostic System
DIGITAL GAUGE
The digital gauge can be used as a diagnostic tool for
many of the DTC’s displayed. To place the gauge into the
diagnostic mode, use the following procedure.
1. Turn the ignition switch ON.
2. Depress and hold both Mode and Set buttons
together for approximately 10 seconds after which
the letters “dIAg” will appear on the LCD momen-
tarily followed by COOL.

NOTE: The display on the gauge will display in
SAE (speedometer in MPH mode) or Metric (speed-
ometer in km/h mode), For example to read tem-
perature in degrees Celsius, select km/h mode on
the gauge or to read Fahrenheit, select MPH mode.
3. Cycle the display by depressing either the Set or
Mode button to step to the desired function.
EFI004
NOTE: The gauge can be utilized dynamically
(engine running/vehicle moving) or statically
(engine/vehicle stopped).
Examples of Static checks: Battery voltage, fuel
gauge/sensor, and TPS (0% @ closed throttle, 95-100%
@ WOT).
EFI007
Examples of Dynamic checks: Battery charging, coolant
temperature including fans ON/OFF (see below),
MAP/IAT, tachometer, and speedometer signal.
