Test Procedure 

Unit output voltage inspection

• Preparation
• • ECT sensor 2 2P connector: disconnected

• Procedure
• • Jump ECT sensor 2 2P connector terminals No. 1 and No. 2 with a jumper wire.
  • Turn the vehicle to the ON mode.
  • Confirm the HDS [ECT Sensor 2 Voltage].

• Normal Conditions
• • -

    HDS [ECT Sensor 2 Voltage] value is less than 4.92 V  .

Results 

• If it is normal, there is a problem with ECT sensor 2.
• If it is abnormal, there is a problem with other related components.

TW2 [TW2_SENSOR], SG6 Open Wire Inspection 

NOTICE: 

Before disconnecting the PCM connector, jump the SCS line with the HDS, and wait more than 1 minute.

Test Procedure 

• Preparation
• • -

    ECT sensor 2 2P connector: disconnected

  • -

	SG6 open wire inspection	OFF			There is less than 1 Ohm

Results 

• If abnormal, there is a problem in the circuit.

PCM Inspection 

Test Procedure 

• If the other inspection item (s) indicated a normal condition, then it is determined that the remaining PCM is the cause.

Results 

• There is a problem with the PCM.
