Cruise Control Ecu Circuit Check
- Make voltage circuit checks on harness side of CC ECU harness connector with connector installed on CC ECU. See Figure
and Fig 1
.DO NOT
make any circuit checks directly on terminals of CC ECU without harness connector installed or CC ECU may be damaged. If voltage checks are within specification, go to next step.
- To check resistance circuits, ensure ignition is off. Disconnect harness connector at CC ECU. Using ohmmeter, make indicated circuit checks on harness side of disconnected CC ECU harness connector. See Figure
and Fig 2
.DO NOT
make any circuit checks directly on terminals of CC ECU with harness connector installed or CC ECU may be damaged. If all circuit checks are okay but system still does not function, substitute a known good CC ECU and recheck system operation.
