4. Is resistance within specification?

   YES 

   • Go to next procedure.

   NO 

   • Repair as necessary and go to "Verification Of Vehicle Repair " procedure.

■ Check For Open In Signal Circuit 

1. IG KEY OFF.
2. Disconnect VCMA harness connector and PCM/ECM harness connector.
3. Measure resistance between both ends of signal line.

   Specification:  Approx. 0 Ω

4. Is resistance within specification?

   YES 

   • Go to next procedure.

   NO 

   • Repair as necessary and go to "Verification Of Vehicle Repair " procedure.
