Pinpoint Tests: Notes

Diagnostics in this service information assume a certain skill level and knowledge of Ford-specific diagnostic practices. Refer to DIAGNOSTIC METHODS for information about these practices.

• Carry out OBD  procedures KOEO  and KOER  .
• Retrieve and record all DTCs.
• Repair all non-transmission DTCs first.
• Repair all transmission DTCs second.
• Clear all CMDTCs  and attempt to repeat them.
• Repair all continuous codes.
• If only pass DTCs are obtained, refer to Component Tests for further information and diagnosis.

Transmission solenoid power is provided by the transmission solenoid power control relay (inside the PCM) to all transmission solenoids. If the power circuit to the transmission solenoids or the transmission solenoid power control relay fails open, all solenoids are failed electrically off. Check for open, short to ground or the transmission connector disconnected. The transmission solenoid power control relay disables power to the transmission solenoids when certain transmission DTCs are set.
