System Inspection
■ Back-Up Voltage Inspection
1.

Ignition "OFF"

2.

Disconnect PCM connector.

3.

Ignition "ON"

4.

Measure voltage between terminal 6 of the PCM harness connector and chassis ground.

Specification : Remain stable at battery voltage

5.

Are circuits remaining stable at battery voltage?

▶ Using a GDS, check PCM software version and upgrade as necessary. If version is the newest one, check PCM for contamination, deterioration, or damage. Substitute with a known-good PCM and check for proper operation. If the problem is corrected, replace PCM and then go to "Verification of Vehicle Repair" procedure.

note

It is necessary to perform the TPS adaptation procedure with GDS when the throttle body assembly or PCM is replaced.

■ TPS adaptation procedure

1.

Erase previous TPS adaptation value using GDS.

2.

Ignition "OFF" and then "ON" without cranking. Wait for 10 seconds under enable conditions

- Enable conditions : Battery 〉10V & Intake Air Temp. 〉5.3℃(41.5℉) & 5.3℃(41.5℉) 〈 Engine Coolant Temp. 〈99.8℃(211.6℉)

3.

After TPS adaptation, the system normality should be confirmed by reading out "FMY" on the GDS.

▶ If voltage fluctuates, check circuit for loose, bent or corroded terminals, Repair as necessary and go to "Verification of Vehicle Repair" procedure.
