No
  • If the fuse is not installed correctly, install it correctly, then go to Step 15.
  • If fuse has been melted, replace it, then go to Step 15.
12 INSPECT TCM 20A FUSE TERMINAL FOR POOR CONNECTION 
  • Switch the ignition OFF (LOCK).
  • Inspect for poor connection (such as damaged, corrosion)
  • Is there any malfunction?
 Yes Repair or replace the terminal, then go to Step 15.
No Go to the next step.
13 INSPECT B+ CIRCUIT FOR OPEN CIRCUIT 
  • Switch the ignition OFF (LOCK).
  • Inspect for continuity between battery positive terminal (wiring harness-side) and TCM terminal A1 (wiring harness-side).
  • Is there continuity?
 Yes Go to the next step.
No Repair or replace the wiring harness for a possible open circuit, then go to Step 15.
14 INSPECT GND CIRCUIT FOR OPEN CIRCUIT 
  • Switch the ignition OFF (LOCK).
  • Inspect for continuity between TCM terminal A9 (wiring harness-side) and body GND.
  • Is there continuity?
 Yes Go to the next step.
No Repair or replace the wiring harness for a possible open circuit, then go to the next step.
15 VERIFY DTC TROUBLESHOOTING COMPLETED 
  • Make sure to reconnect all the disconnected connectors.
  • Clear the DTC using the M-MDS.
  • Perform the following procedure to ensure that the DTC has been resolved:
    • Start the engine.
    • Warm up the engine and transaxle.
    • Drive the vehicle in D position and make sure that the gears shift smoothly from 1GR to 6GR.
  • Is the same DTC present?
 Yes Replace the TCM, then go to the next step.
(See TCM REMOVAL/INSTALLATION .)
No Go to the next step.
16 VERIFY NO DTCs ARE PRESENT
