ETC Motor Inspection

CAUTION: 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) 3. After TPS adaptation, the system normality should be confirmed by reading out "FMY" on the Scan Tool
(1) Visually/physically inspect the restriction or any foreign objects in throttle body
(2) Clean or replace as necessary and go to "Verification of Vehicle Repair" procedure.
If OK, go to next step as below
(3) Ignition "OFF"
(4) Disconnect the ETC motor harness connector
(5) Measure resistance between terminals 3 and 6 of the ETC motor Connector (Component side)
A. Specification: 1.2 - 1.8 Ohms at 20 °C (68 °F)

(6) Is resistance within the specification ?
YES
1) Go to W/Harness Inspection
NO
1) Check throttle body for contamination, deterioration, or damage. Substitute with a known-good throttle body and check for proper operation. If the problem is corrected, replace throttle body and then go to "Verification of Vehicle Repair" procedure.
