WARNING: This page is about a different car, the 2011 Toyota Matrix. However, it is still accessible from the selected car via links, so may be relevant.
- CHECK HARNESS AND CONNECTOR (TERMINAL TC of DLC3 - ECM)
- Disconnect the ECM connector.
- Measure the resistance according to the value(s) in the table below.
Standard Resistance (2ZR-FE)
Tester Connection Condition Specified Condition A37-41 (TC) - E15-13 (TC) Always Below 1 Ω Standard Resistance (2AZ-FE)
Tester Connection Condition Specified Condition A37-27 (TC) - E15-13 (TC) Always Below 1 Ω - Reconnect the ECM connector.
NG → REPAIR OR REPLACE HARNESS OR CONNECTOR (DLC3 - ECM)
OK: Go to next step
- CHECK HARNESS AND CONNECTOR (TERMINAL CG of DLC3 - BODY GROUND)
- Measure the resistance according to the value(s) in the table below.
Standard Resistance
Tester Connection Condition Specified Condition E15-4 (CG) - Body ground Always Below 1 Ω
NG → REPAIR OR REPLACE HARNESS OR CONNECTOR (DLC3 - BODY GROUND)
OK: Go to next step
- Measure the resistance according to the value(s) in the table below.
- CHECK HARNESS AND CONNECTOR (TERMINAL TC of DLC3 - BODY GROUND)
- Measure the resistance according to the value(s) in the table below.
Standard Resistance
Tester Connection Condition Specified Condition E15-13 (TC) - Body ground Always 10 kΩ or higher
NG → REPAIR OR REPLACE HARNESS OR CONNECTOR OR EACH ECU
OK → See step 4
- Measure the resistance according to the value(s) in the table below.
