INSPECTION PROCEDURE

ПРИМЕЧАНИЕ:

After replacing the ECM, the new ECM needs registration (see page RAV4_ACA30 RM000000TJ400AX.html) and initialization (see page RAV4_ACA30 RM000000TIN009X.html).

1. Connect the intelligent tester to the DLC3.
   

2. Turn the ignition switch on (IG) and turn the tester ON.
   

3. Use the table below to troubleshoot each problem symptom.
   

   Result:

   Condition	Proceed to
   MIL remains ON	A
   MIL is not illuminated	B

1. Enter the following menus: Powertrain / Engine and ECT / DTC.
   

2. Read pending DTCs.
   

   Result:

   Display (DTC Output)	Proceed to
   No DTCs	A
   Engine related DTCs	B

1. Disconnect the A12 ECM connector.
   

2. Turn the ignition switch on (IG).
   

3. Check that the MIL does not illuminate.
   

   OK:

   MIL does not illuminate.
   

4. Reconnect the ECM connector.
   

1. Disconnect the E22 combination meter connector.
   

2. Disconnect the A12 ECM connector.
   

3. Measure the resistance of the wire harness side connectors.
   

   Standard resistance (Check for short):

   Tester Connection	Specified Condition
   A12-12 (W) or E22-8 (EFI) - Body ground	10 kΩ or higher

4. Reconnect the combination meter connector.
   

5. Reconnect the ECM connector.
   

1. Check if the MIL is illuminated when the ignition switch is turned on (IG).
   

   OK:

   MIL illuminates.
   

1. Check the combination meter circuit (see page RAV4_ACA30 RM0000020M2000X.html).
   

   OK:

   Combination meter circuit is normal.
