WIRING DIAGRAM

HINT:

When the warning lights continue to blink, a ground short in the wiring of terminal TC of the DLC3 or an internal ground short in one or more ECUs is suspected.

INSPECTION PROCEDURE

NOTICE:

When replacing the brake actuator assembly, perform zero point calibration (COROLLA_ZRE142 RM000000XHR08KX.html).

1. Check if a CAN communication system DTC is output (COROLLA_ZRE142 RM000000XHV0F2X.html).
   
   

   Result:

   
   

   Result	Proceed to
   DTC is not output	A
   DTC is output	B

1. Turn the ignition switch to ON.
   

2. Measure the voltage according to the value(s) in the table below.
   

   Standard Voltage:

   Tester Connection	Switch Condition	Specified Condition
   E11-13 (TC) - E11-4 (CG)	Ignition switch ON	11 to 14 V

   
   

   Result:

   
   

   Result	Proceed to
   NG	A
   OK	B

1. Turn the ignition switch off.
   

2. Disconnect the ECM connector.
   

3. Measure the resistance according to the value(s) in the table below.
   
   

   Standard Resistance:

   for 2AZ-FE:

   Tester Connection	Condition	Specified Condition
   E11-13 (TC) - A50-27 (TC)	Always	Below 1 Ω
   E11-13 (TC) - Body ground	Always	10 kΩ or higher

   for 2ZR-FE:

   Tester Connection	Condition	Specified Condition
   E11-13 (TC) - A50-41 (TC)	Always	Below 1 Ω
   E11-13 (TC) - Body ground	Always	10 kΩ or higher

1. Measure the resistance according to the value(s) in the table below.
   

   Standard Resistance:

   Tester Connection	Condition	Specified Condition
   E11-4 (CG) - Body ground	Always	Below 1 Ω

1. Turn the ignition switch off.
   

2. Reconnect the ECM connector.
   

3. Using SST, connect terminals TC and CG of the DLC3.
   

SST

4. Turn the ignition switch to ON.
   

5. Check that the check engine warning light is blinking.
   
   

   Result:

   
   

   Result	Proceed to
   Check engine warning light is blinking	A
   Check engine warning light is not blinking	B
