Test 11: O/D Off Circuit (A/T)

NOTE: Ensure overdrive off system is operating normally. Repair system as necessary.
  1. Disconnect CC ECU connector (10-pin connector "B" with motor actuator). Set overdrive main switch to ON position. Ensure continuity exists between ground and CC ECU connector terminal No. B2 (with motor actuator) or No. 7 (with vacuum actuator), (Pink wire). If continuity is present, go to next step. If continuity is not present, repair open in harness between CC ECU connector terminal No. B2 (with motor actuator) or No. 7 (with vacuum actuator), (Pink wire) and overdrive main switch.
  2. Set overdrive main switch to OFF position. Ensure no continuity exists between ground and CC ECU connector terminal No. B2 (with motor actuator) or No. 7 (with vacuum actuator), (Pink wire). If continuity is present, replace CC ECU and retest system. If continuity is not present, repair short in harness between CC ECU connector terminal No. B2 (with motor actuator) or No. 7 (with vacuum actuator), (Pink wire) and overdrive main switch.
