• The control module suspends all message transmission.
• The control module uses default values for all parameters received on the serial data circuits.
• In the TCM, DTC U0073 will cause the transmission to go into default gears.
• In the ECM and TCM, DTC U0073 will cause the malfunction indicator lamp (MIL) to illuminate.
• The ECM/TCM modules turn off the MIL after 4 consecutive ignition cycles that the diagnostic runs and does not fail.
• If equipped with eAssist, the hybrid powertrain control module turns off the MIL after the diagnostic runs and does not fail during subsequent ignition cycles. Normal operation will resume 5 seconds after subsequent ignition cycle.
• A current DTC clears when the malfunction is no longer present.
• A history DTC clears when the module ignition cycle counter reaches the reset threshold of 50, without a repeat of the malfunction.
