DRIVE LINE CONTROL SYSTEM (TOD) 4B2–60 Step Action Yes No 1 1. Clear the trouble code. Is there DTC31 (P1721)? Go to Step 2 Refer to “Trouble intermittently observed”. 2 1. Turn off the starter switch. Is the continuity established between terminals (B–67)4 and Go to Step 3 Go to Step 5 3 1. Connect the ECU connector. Does the voltage between terminals 4 and 20 indicate at least Go to Step 4 Go to Step 6 4 Is the battery voltage always observed between terminals 4 and The harness is short–circuited on the battery. Repair the circuit. Go to Step 8 Go to Step 6 5 1. Disconnect the A–3 connector. Is the continuity established between transfer connector The harness is the circuit. Go to Step 8 Replace the transfer electromagnetic coil (solenoid clutch). Go to Step 8 6 1. Turn off the starter switch. Is the resistance between the connector (B–67) terminal 4 and 12 ∼ 5.0 W ? The ECU has failed. Replace the ECU Go to Step 8 Go to Step 7 7 Is the resistance between the transfer connector (A–3) terminal 8 ∼ 5.0 W ? The harness is disconnection or short to GND. Repair the circuit. Go to Step 8 Replace the transfer electromagnetic coil (solenoid clutch). Go to Step 8 8 1. Check that all the parts are mounted. Is this step complete? Repeat the “Diagnosis Flow”. Return to Step 8 |
