1. CHECK TCM (POWER SOURCE, BODY GROUND) Disconnect the TCM connector. Measure the voltage according to the value(s) in the table below. Standard Voltage Tester Connection Switch Condition Specified Condition B31-18 (+B) - Body ground Ignition switch ON 11 to 14 V Turn the ignition switch off. Measure the resistance according to the value(s) in the table below. Standard Resistance Tester Connection Condition Specified Condition B31-8 (E1) - Body ground Always Below 1 ohms TEXT IN ILLUSTRATION *a Front view of wire harness connector (to TCM) NG --> REPAIR OR REPLACE HARNESS OR CONNECTOR (TCM - BATTERY, BODY GROUND) OK: Go to next step
2. CHECK HARNESS AND CONNECTOR (ECM - TCM) Disconnect the ECM connector. Disconnect the TCM connector. Measure the resistance according to the value(s) in the table below. Standard Resistance Tester Connection Condition Specified Condition B30-24 (CAN+) - B31-6 (CAN+) Always Below 1 ohms B30-1 (CAN-) - B31-7 (CAN-) Always Below 1 ohms B30-24 (CAN+) or B31-6 (CAN+) - Body ground or other terminals Always 10 kohms or higher B30-1 (CAN-) or B31-7 (CAN-) - Body ground or other terminals Always 10 kohms or higher NG --> REPAIR OR REPLACE HARNESS OR CONNECTOR OK: Go to next step
3. CHECK IF DTC OUTPUT RECURS (DTC U0100) Connect the Techstream to the DLC3. Turn the ignition switch to ON. Turn the Techstream on. Enter the following menus: Powertrain / ECT / Trouble Codes / Clear. Replace the TCM. Refer to «REMOVAL»(ref-451170-S32416003882012020700000) . HINT: Replace the TCM with the TCM of a normally functioning vehicle of the same model. Start the engine. Enter the following menus: Powertrain / ECT / Trouble Codes. Read the DTCs using the Techstream. RESULT Result Proceed to U0100 is output A DTCs are not output B B --> See step 5 A --> See step 4
4. REPLACE ECM. Refer to «REMOVAL»(ref-451166-S22630148492012020700000)
5. REPLACE TCM. Refer to «REMOVAL»(ref-451170-S32416003882012020700000)

Note. Inspect the fuses for circuits related to this system before performing the following inspection procedure.

Scheme 433

1. CHECK TCM (TCM - BODY GROUND) Disconnect the TCM connector. Measure the resistance according to the value(s) in the table below. Standard Resistance Tester Connection Condition Specified Condition B31-8 (E1) - Body ground Always Below 1 ohms TEXT IN ILLUSTRATION *a Front view of wire harness connector (to TCM) NG --> REPAIR OR REPLACE HARNESS OR CONNECTOR OK: Go to next step
2. CHECK HARNESS AND CONNECTOR (INTEGRATION RELAY - TCM) Remove the integration relay from the engine room relay block. Refer to «ON-VEHICLE INSPECTION»(ref-451166-S20720226562012020700000) . Disconnect the TCM connector. Measure the resistance according to the value(s) in the table below. Standard Resistance Tester Connection Condition Specified Condition 1B-4 - B31-18 (+B) Always Below 1 ohms 1B-4 or B31-18 (+B) - Body ground Always 10 kohms or higher NG --> REPAIR OR REPLACE HARNESS OR CONNECTOR OK --> See step 3
3. GO TO SFI SYSTEM (ECM POWER SOURCE CIRCUIT). Refer to «ECM Power Source Circuit»(ref-451172-S01002187532012020700000)
