• Ignition off. Wait until the gear selector indicator or light goes out (normally takes approximately 7 seconds). If the gear selector indicator or light does not light up from the beginning due to a fault, wait for 3 minutes from when the ignition is switched off
• Expose the transmission control module (TCM). See TRANSMISSION CONTROL MODULE (TCM)
  NOTE: When taking readings at connectors A and B (not on the actual transmission), the transmission control module (TCM) does not need to be disconnected from the transmission. If the control module is not disconnected, calibration does not need to be carried out.
• Remove the connectors from the transmission control module (TCM)
• Check in particular that the male and female terminals on the control module, the control module connectors and on the transmission are intact, secure and cannot be pressed in. Check that the female terminal cables are securely connected
• In particular, check the terminal pins relevant to the diagnostic trouble code (DTC)/symptom. See also, see SIGNAL SPECIFICATION
• Connect the adapter see 9512904 to the connectors on the transmission control module (TCM) or transmission. Connect the breakout box see 9511428 to the adapter
• The breakout box is designed to facilitate reading off the control module input and output signals when the control module is connected; and the resistance of the cable and component when the control module is disconnected. The use of a breakout box reduces the risk of accidental short-circuited cables and damage to the connector pins.
