W/Harness Inspection

Terminal and Connector Inspection

1. Many malfunctions in the electrical system are caused by poor harness and terminals. Faults can also be caused by interference from other electrical systems, and mechanical or chemical damage.
2. Thoroughly check connectors for looseness, poor connection, bending, corrosion, contamination, deterioration, or damage.
3. Has a problem been found ?






Power Circuit Inspection

1. Check voltage
(1) IG "OFF".
(2) Disconnect TPS connector.
(3) IG "ON" and ENG "OFF"
(4) Measure the voltage between terminal 1 of TPS harness connector and chassis ground.

Specification : Approx. 5V





(5) Is the measured voltage within specification ?





2. Check short in harness
(1) IG "OFF".
(2) Disconnect TPS connector and PCM connector.
(3) Measure the resistance between terminal 1 and 2 of TPS harness connector.
(4) Measure the resistance between terminal 1 and 3 of TPS harness connector.
(5) Measure the resistance between terminal 1 and 5 of TPS harness connector.
(6) Measure the resistance between terminal 1 and 8 of TPS harness connector.

Specification : Infinite





(7) Is the measured resistance within specification ?





** Procedure of ETS Initialization
1. Erase the trouble codes on PCM
2. Turn the ignition key off and keep this condition until the main relay is turned off. (It will takes 10 second)
3. Turn ignition key on more than 1 second to record the throttle motor position on the EEPROM
