Power Circuit Inspection

■ Circuit open Inspection 

1. Ignition off & Engine off.
2. Disconnected "ATM solenoid valve" connector and PCM/TCM connector.
3. Measure resistance between power of ATM solenoid valve connector and power of PCM TCM connector.

   Specification:  Approx. 0 Ω

4. Is the measured resistance within specification?

   YES 

   • Go to "Circuit short Inspection" procedure below.

   NO 

   • Check circuit open of power and go to "Verification of Vehicle Repair " procedure.

■ Circuit short Inspection 

1. Ignition off & Engine off.
2. Disconnected "ATM solenoid valve connector and PCM/TCM connector.
3. Measure a resistance between power of ATM solenoid valve connector and chassis ground.

   Specification:  Infinite

4. Is the measured resistance within specifications?

   YES 

   • Substitute with a known-good PCM/TCM and check for proper operation. If the problem is corrected, replace PCM/TCM and then go to "Verification of Vehicle Repair " procedure.

   NO 

   • Check harness for circuit short. Repair as necessary and go to "Verification of Vehicle Repair " procedure.
