HINT: The type of ignition switch on this model differs according to the specifications of the vehicle. For the expressions used in this section, refer to the "EXPRESSIONS OF IGNITION SWITCH" precaution (See page ES-1).
1. CHECK AIR FUEL RATIO COMPENSATION SYSTEM
(a) Connect the intelligent tester to the DLC3.
(b) Turn the ignition switch to the ON position.
(c) Select the following menu items: Data List / A/FS B1 S1 and O2S B1 S2.
(d) Warm up the A/F sensor with the engine speed at 2500 rpm for approximately 2 minutes.
(e) Keep the engine speed at 2500 rpm and confirm that the "A/FS B1 S1" and "A/FS BS S1" display is as shown in the illustration.
HINT:
Standard
NOTICE: The A/F sensor has an output delay of a few seconds. |
(f) Confirm that the "O2S B1 S2" and "A/FS BS S1" display changes between 0 to 1 V with the engine speed at 2500 rpm.
OK: The voltage output oscillates more than 8 times in 10 seconds.

Terminals of ecu
1. Terminal of ECU
(*1): Models with dynamic laser cruise control
(*2): 2WD model
2. Terminal Inspection
(a) Disconnect the connector and measure the voltage
or resistance on the wire harness side.
HINT:
Voltage cannot be measured with the connector
connected to the skid control ECU ...
Launch Control
Concept
Launch Control enables optimum acceleration
on surfaces with good traction under dry surrounding
conditions.
General information
The use of Launch Control causes premature
component wear since this function represents a
very heavy load for the vehicle.
Do not use Launch Control during the b ...
Insufficient Coolant Temperature for Closed Loop Fuel Control
DESCRIPTION
Refer to DTC P0115 (See page ES-133).
MONITOR DESCRIPTION
The resistance of the ECT sensor varies in proportion to the actual ECT. The
ECM supplies a constant
voltage to the sensor and monitors the signal output voltage of the sensor. The
signal voltage output
varies acc ...
