Pinpoint Tests

NOTE: If equipped, turn the Power Take-Off (PTO) unit off for correct test results. For a description of PTO operation, refer to Transmission Electronic Control System. On-Board Diagnostic is not accessible when the PTO unit is in operation. SSB is on when the PTO is in operation.

Any time an electrical connector or solenoid body is disconnected, inspect the connector for terminal condition, corrosion and contamination. Also inspect the connector seal for damage. Clean, repair or install a new connector as required.
