FUNCTION

CONSULT-II diagnostic test modes

Diagnostic test mode	Function
Work support	This mode enables a technician to adjust some devices faster and more accurately by following the indications on the CONSULT-II unit.
Self-diagnostic results	Self-diagnostic results such as 1st trip DTC, DTCs and 1st trip freeze frame data or freeze frame data can be read and erased quickly.*1
Data monitor	Input/Output data in the ECM can be read.
Active test	Diagnostic Test Mode in which CONSULT-II drives some actuators apart from the ECMs and also shifts some parameters in a specified range.
SRT confirmation	The status of system monitoring tests and the self-diagnosis status/result can be confirmed.
ECM part number	ECM part numbers can be read.

WORK ITEM	CONDITION	USAGE
IGNITION TIMING ADJ	- IGNITION TIMING FEEDBACK CONTROL WILL BE HELD BY TOUCHING "START". AFTER DOING SO, ADJUST IGNITION TIMING WITH A TIMING LIGHT BY TURNING THE CAMSHAFT POSITION SENSOR.	When adjusting initial ignition timing
FUEL PRESSURE RELEASE	- FUEL PUMP WILL STOP BY TOUCHING "START" DURING IDLING. CRANK A FEW TIMES AFTER ENGINE STALLS.	When releasing fuel pressure from fuel line

IGNITION TIMING ADJ

CONDITION- IGNITION TIMING FEEDBACK CONTROL WILL BE HELD BY TOUCHING "START". AFTER DOING SO, ADJUST IGNITION TIMING WITH A TIMING LIGHT BY TURNING THE CAMSHAFT POSITION SENSOR.

USAGEWhen adjusting initial ignition timing

FUEL PRESSURE RELEASE

CONDITION- FUEL PUMP WILL STOP BY TOUCHING "START" DURING IDLING. CRANK A FEW TIMES AFTER ENGINE STALLS.

USAGEWhen releasing fuel pressure from fuel line

SELF DIAGNOSTIC MODE — DTC and 1st Trip DTC

Freeze Frame Data and 1st Trip Freeze Frame Data

Freeze frame data items

Freeze frame data item*	Description
DIAG TROUBLE CODE [PXXXX]	- Engine Control component part/control system has a trouble code, it is displayed as "PXXXX". [Refer to "Alphabetical & P No. Index for DTC" (EC-7003).]
FUEL SYS DATA	- "Fuel injection system status" at the moment a malfunction is detected is displayed. - One mode in the following is displayed. "MODE 2": Open loop due to detected system malfunction "MODE 3": Open loop due to driving conditions (power enrichment, deceleration enrichment) "MODE 4": Closed loop - using oxygen sensor(s) as feedback for fuel control "MODE 5": Open loop - has not yet satisfied condition to go to closed loop
CAL/LD VALUE [%]	- The calculated load value at the moment a malfunction is detected is displayed.
COOLANT TEMP [°C] or [°F]	- The engine coolant temperature at the moment a malfunction is detected is displayed.
