Eclipse GT V6-3.0L SOHC (2000)
Connectors: C-14, C-110
CIRCUIT OPERATION
-
A battery positive voltage is applied on the data link connector power terminal (terminal 16). The ground terminals (terminal 4, 5) are grounded to
the vehicle body.
COMMENT
-
The cause is probably a defect in power supply system (including ground) for the on-board diagnostic test mode line.
TROUBLESHOOTING HINTS
The most likely causes for this case:
-
Malfunction of the data link connector.
-
Damaged harness wire.
DIAGNOSIS
STEP 1. Check the power supply line at data link connector C-29.
1. Measure voltage between terminal 16 and ground.
-
Voltage should be battery positive voltage.
If within specifications, go to Step 2.
If not within specifications, check the intermediate connectors C-89, C-110 and C-104, and repair or replace if needed. Refer to Harness
Connector Inspection. If intermediate connectors C-89, C-110 and C-104 are in good condition, repair the harness wire between data link
connector C-29 and fusible link (1).
Then confirm that the malfunction symptom is eliminated.
STEP 2. Check the ground line at the data link connector C-29.
1. Check for the continuity between terminal 4, 5 and ground.
-
Should be less than 2 ohms.
If less than 2 ohms , replace the scan tool.
If open circuit, repair the harness wire between the data link connector C-29 and the ground.
Then confirm that the malfunction symptom is eliminated.
