  1. Disconnect the a19 ecu connector.
  2. Measure the voltage and resistance of the wire harness side connector.

Hint:

The voltage cannot be measured with the connector connected to the skid control ecu as the connector is water resistant.

Unmatched key code
Description This dtc is output when a key code that has not been registered in the transponder key ecu is inserted into the ignition key cylinder. Inspection procedure Reregister key Clear the dtc (see page ei-18). Reregister the key code with the transponder key ecu (see ...

Security indicator light circuit
Description When the transponder key is registered, the transponder key ecu indicates the key registration condition by lighting up, blinking or turning off the security indicator. Wiring diagram Inspection procedure Perform active test by intelligent tester (security indicator light) ...

Test mode procedure
Hint: By switching the skid control ecu from normal mode to test mode, abnormality detection sensitivity is enhanced and troubleshooting can be conducted efficiently. Perform a sensor check in test mode after the speed sensor or sensor rotor has been repaired or replaced. If the igniti ...
