―  SSA
―  SSB
―  SSC
―  SSD
•  Using the IDS/PDS, verify the operation status of shift solenoid A, B, C and D while driving.
―  1GR: SSA on, SSB off, SSC off, SSD on
―  2GR: SSA on, SSB off, SSC on, SSD on
―  3GR: SSA on, SSB on, SSC off, SSD on
―  4GR: SSA off, SSB off, SSC off, SSD on
―  5GR: SSA off, SSB off, SSC on, SSD on
•  Is the shift solenoid operation normal?
Yes
Go to the next step.
No
