Any change in the values indicates a poor connection. Was a connector problem found?
 | ▶ Repair the connector. Go to "Verification of Vehicle Repair" procedure. |
 | ▶ Go to "ETC Output 1 Circuit Inspection" procedure. |
Disconnect the ETC Motor, TPS and PCM/ECM connectors and inspect for looseness, poor connection, bending, corrosion, contamination, deterioration or damage. Reconnect the connectors.
Connect the GDS and go to “Current Data”.
Monitor TPS values in Current Data, check and wiggle the harness(es), connector(s), and terminal(s).
Any change in the values indicates a poor connection. Was a connector problem found?
| ▶ Repair the connector. Go to "Verification of Vehicle Repair" procedure. |
| ▶ Go to "ETC Output 1 Circuit Inspection" procedure. |
