Wiring diagram
Inspection procedure
- Check can communication system
- Check if the can communication system dtc is output (see page ca-34).
Result 
- Inspect skid control ecu connector
- Check if the skid control ecu connector is properly installed.
Ok: the skid control ecu connector is properly installed.
- Check wire harness (skid control ecu - battery and body ground)
- Disconnect the a19 ecu connector.
- Measure the resistance of the wire harness side connector.
Standard resistance 
- Measure the voltage of the wire harness side connector.
Standard voltage 
- Perform active test by intelligent tester (abs warning light)
- Select the active test, generate a control command, and then check that the abs warning light operates.
Ok: the abs warning light is turned on or off.
Hint:
When the abs warning light remains illuminated, opens in the wire harness of the combination meters or abnormalities in the meter circuit should be considered.
