Test Preparation

Check level and condition of transaxle fluid. Check PCM memory for any stored DTCs. If no DTCs are present, proceed to appropriate step (WITH SCAN TOOL or WITHOUT SCAN TOOL). If codes are present, diagnose and repair all PCM related trouble codes. Clear PCM trouble code memory.

1) Using scan tool, verify shift selector readings match actual shifter position. Turn ignition on. Using scan tool, access actuator test in special test menu. Move gear selector as to each gear position. This should cause a specific line actuator to operate. See LINE ACTUATOR SELECT  table.

2) If the line actuator is operating, it will audibly operate at a fixed duty cycle for 6 seconds and then click on and off. Clicking will repeat until the next gear is selected or ignition turned off.

3) To check actuator resistance, disconnect actuator connector plate. Using a DVOM, measure resistance at actuator terminals. On all actuators resistance should be more than 4 ohms.

LINE ACTUATOR SELECT

Selected Gear Resistance (1) Actuator
"D2" 4 Ohms 2nd Actuator
"D3" 4 Ohms 3rd Actuator
"D4" 4 Ohms 4th Actuator
"R" 4 Ohms TCC Actuator
"N" or "P" 4 Ohms Line Actuator
(1) Measured at actuator terminals.
