CAUTION / NOTICE / HINT
NOTICE:
When replacing the skid control ECU (brake actuator assembly), perform zero point
calibration and store system information (See page
).
PROCEDURE
1. |
RECONFIRM DTC |
HINT:
These codes are detected when a problem is determined in the skid control ECU (brake actuator assembly).
The solenoid circuits are in the skid control ECU (brake actuator assembly).
Therefore, solenoid circuit inspection and solenoid unit inspection cannot be performed. Be sure to check if any DTCs are output before replacing the skid control ECU (brake actuator assembly).
(a) Clear the DTC (See page
).
(b) Turn the ignition switch off.
(c) Start the engine.
(d) Drive the vehicle at a speed of 20 km/h (12 mph) or more for 30 seconds or more.
(e) Check if the same DTC is recorded (See page
).

Transmission Fluid Temperature Sensor "A" Circuit Range/Performance (P071000)
DESCRIPTION
The No. 1 ATF temperature sensor converts the fluid temperature into a resistance
value for use by the ECM.
The ECM applies a voltage to the temperature sensor through terminal THO1 of
the ECM.
The sensor resistance changes with the ATF temperature. As the temperature becomes
