▶ Substitute with a known - good ECTS and check for proper operation. If the problem is corrected, replace
ECTS and go to "Verification of Vehicle Repair" procedure.
2.
Check PCM
1)
IG "OFF" and connect scantool.
2)
Connect probe to terminal 3 of ECTS harness connector.
3)
IG "ON" and ENG "OFF" and simulation Function on scantool.
4)
Simulate voltage at terminal 3 of ECTS harness connector.

Does the signal value of ECT sensor change according to simulation voltage ?
YES
▶ Thoroughly check connectors for looseness, poor connection, bending, corrosion, contamination, deteriora-
tion, or damage. Repair or replace as necessary and go to "Verification of Vehicle Repair" procedure.
NO
▶ Substitute with a known - good PCM and check for proper operation. If the problem is corrected, replace PCM
and go to "Verification of Vehicle Repair" procedure.
NOTE
There is a memory reset function on scantool that can erase optional parts automatically detected and memorized
by PCM.
Before or after testing PCM on the vehicle, use this function to reuse the PCM on the others.

DTC P1295 ETC (ELECTRONIC THROTTLE CONTROL) SYSTEM
MALFUNCTION - POWER MANAGEMENT
COMPONENT LOCATION

GENERAL DESCRIPTION
EC81A79C
The Electronic Throttle Control(ETC) system is made of the components throttle body, Throttle Position Sensor(TPS)1&
2 and Accelerator Position Sensor(APS) 1&2. The throttle body contains the actuator, the throttle plate and the throttle
position sensor (potentiometer), which are integrated in one housing. The actuator consists of a DC motor with a two-stage
gear. The opening angle of the throttle valve is detected by the throttle position sensor which is mounted on the throttle
body. And it provides feedback to the ECM to control the throttle motor in order to control the throttle valve opening angle
properly in response to the driving condition.
DTC DESCRIPTION
E476FA42
If power management mode is recognized under detecting condition, PCM sets P1295. And MIL(Malfunction Indication
Lamp) turns on.
