VALUES ON THE DIAGNOSIS TOOL
NOTE:
• The following table includes information (items) inapplicable to this vehicle. For information (items) applica- ble to this vehicle, refer to CONSULT display items.
• Numerical values in the following table are reference values.
• These values are input/output values that ECM receiv es/transmits and may differ from actual operations.
Example: The ignition timing shown by the timing light may differ from the ignition timing displayed on the
data monitor.
This occurs because the timing light shows a value calculated by ECM according to signals received from
the camshaft position sensor and other sensors related to ignition timing.
• For outlines of following items, refer to EC-77, "CONSULT Function"
.
Monitor Item Condition Values/Status
ENG SPEED • Run engine and compare CONSULT value with the tachometer indication.Almost the same speed as
the tachometer indication.

ECM
*1: Accelerator pedal position sensor 2 signal and throttle position sensor 2 signal are converted by ECM internally. Thus, the
y differ
from ECM terminals voltage signal.
*2: Before measuring the voltage, confirm that the battery is fully charged. Refer to PG-4, "How to Handle Battery"
.
