Component Inspection

Ignition "OFF"
Measure resistance between terminals 76 and 78 of the ECM connector (ECM side)
Specification : Approx. 110~130Ω

Fig 1: Measuring Resistance Between Terminals 76 And 78 Of ECM Connector (ECM Side)
Is resistance within the specification?
YES
- Check for poor connection between ECM and component: backed out terminal, improper mating, broken locks or poor terminal to wire connection. Repair as necessary and go to "VERIFICATION OF VEHICLE REPAIR " procedure
NO
- Check ECM for contamination, deterioration, or damage. Substitute with a known-good ECM and check for proper operation. If the problem is corrected, replace ECM and then go to "VERIFICATION OF VEHICLE REPAIR " procedure.
  NOTE: It is necessary to perform the TPS adaptation procedure with Scan tool when the throttle body assembly or ECM is replaced.
■ TPS adaptation procedure
1. Erase previous TPS adaptation value using Scan tool.
2. Ignition "OFF" and then "ON" without cranking. Wait for 10 seconds under enable conditions
  - Enable conditions : Battery >10V & Intake Air Temp. > 5.3°C (41.5°F) & 5.3°C (41.5°F) < Engine CoolantTemp. <99.8°C (211.6°F)
3. After TPS adaptation, the system normality should be confirmed by reading out "FMY" on the Scan Tool
