Drive Cycle Test Notes

- The Transmission Drive Cycle Test must be followed exactly. Malfunctions have to occur four times consecutively for codes 49, 59, 617, 618, and 619 to be set, and five times consecutively for continuous code 62 or 628.

- After performing the Quick Test, use the Transmission Drive Cycle Test for checking E4OD continuous codes.

- When performing the Drive Cycle Test, refer to the Solenoid operation Chart for proper solenoid operation.

- After the On-Board Diagnostics procedures are completed, service all DTCs.

- Begin with non-transmission related DTCs, then service any transmission related DTCs.

- Refer to the On-Board Diagnostic Trouble Code Description Chart for information on Condition and Symptoms. This chart will be helpful as a reference to aid in diagnosing internal transmission concerns and external non-transmission inputs.

- The Pinpoint Tests are used in diagnosing electrical concerns of the E4OD transmission. Make sure that the vehicle wiring harness and the powertrain control module are diagnosed as well.

- The vehicle wiring harness, powertrain control module and non-transmission sensors may affect transmission operations. Service these concerns first.
