Terminal and Connector Inspection

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.

Thoroughly check connectors for looseness, poor connection, bending, corrosion, contamination, deterioration, or damage.

Has a problem been found?

YES

▶ Repair as necessary and go to "Verification of Vehicle Repair" procedure

▶ Go to " Power Circuit Inspection " procedure.

Power Supply Circuit Inspection

■ Check voltage

IG "OFF" and disconnect ETC Motor & TPS connector.

IG "ON" and ENG "OFF"

Thoroughly check connectors for looseness, poor connection, bending, corrosion, contamination, deterioration, or damage. Repair as necessary and go to "Verification of Vehicle Repair" procedure.

Go to "Check short in power harness" as follows.

■ Check short in power harness

IG "OFF".

Disconnect ETC Motor & TPS connector and PCM connector.

Measure the resistance between TPS1 power and ETC motor (+) terminals of ETC Motor & TPS harness connector.(Measurement "A")

Measure the resistance between TPS1 power and ETC motor (-) terminals of ETC Motor & TPS harness connector.(Measurement "A")

Measure the resistance between TPS1 power and TPS1 ground terminals of ETC Motor & TPS harness connector.(Measurement "B")

10.

11.

Is the measured resistance within specification ?

YES

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.

Repair short in power harness and go to "Verification of Vehicle Repair" procedure.

caution

※ 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 take 10 seconds)

3. Turn ignition key on more than 1second to record the throttle motor position on the EEPROM
