Matrix L4-1.8L (1ZZ-FE) (2008)
INSPECTION PROCEDURE
NOTE: Turn the ignition switch off before measuring the resistances of CAN bus main wires and CAN bus branch wires.
PROCEDURE
1. CHECK FOR OPEN IN CAN BUS WIRE (ECU MAIN BUS WIRE)
(a) Disconnect the ECM connector (E5).
(b) Measure the resistance according to the value(s) in the table below.
Standard resistance:
NG -- REPAIR OR REPLACE CAN MAIN WIRE OR CONNECTOR
OK -- Continue to next step.
2. CHECK ECM POWER SOURCE CIRCUIT
(a) Check the ECM power source circuit (See: Testing and Inspection/Component Tests and General Diagnostics/Crankshaft Position Sensor
).
Result:
C -- REPLACE ECM POWER SOURCE CIRCUIT
B -- CHECK DLC3
A -- Continue to next step.
3. CHECK DLC3
(a) Turn the ignition switch off.
(b) Measure the resistance according to the value(s) in the table below.
Standard resistance:
