• Check for poor connection (damaged/pulled-
out terminals, corrosion, etc.).
• Is connection okay?
4 INSPECT RESISTANCE
• Inspect resistance between ATX connector
terminal B (transaxle case side) and body
ground.
• Is resistance within 10.9—26.2 ohms?
(See K–26 Resistance Inspection (On-Vehicle
Inspection).)
5 INSPECT SHIFT SOLENOID D CONNECTOR
FOR POOR CONNECTION
