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 receives/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
.
