Diagnosis Procedure
1.CONNECTOR INSPECTION
2.CHECK HARNESS CONTINUITY (SHORT CIRCUIT)
Check the continuity between the data link connector terminals.
3.CHECK HARNESS CONTINUITY (SHORT CIRCUIT)
Check the continuity between the data link connector and the ground.
4.CHECK ECM AND IPDM E/R TERMINATION CIRCUIT
3. Check the resistance between the IPDM E/R terminals.
5.CHECK SYMPTOM
Connect all the connectors. Check if the symptoms described in the "Symptom (Results from interview with customer)" are reproduced.
Inspection result
Reproduced>>GO TO 6.
Non-reproduced>>Start the diagnosis again. Follow the trouble diagnosis procedure when past error is detected.
6.CHECK UNIT REPRODUCTION
Perform the reproduction test as per the following procedure for each unit.
NOTE: ECM and IPDM E/R have a termination circuit. Check other units first.
NOTE: Although unit-related error symptoms occur, do not confuse them with other symptoms.
Inspection result
Reproduced>>Connect the connector. Check other units as per the above procedure.
Non-reproduced>>Replace the unit whose connector was disconnected.
Valet hand-off
When you have to leave a key with a valet, give
them the Intelligent Key itself and keep the mechanical
key with you to protect your belongings.
To prevent the glove box and the trunk from being
opened during valet hand-off, follow the procedures
below.
1. Push the trunk cancel switch to t ...
Ignition signal
Description
The ignition signal from the ECM is sent to and amplified by the power
transistor. The power transistor turns
ON and OFF the ignition coil primary circuit. This ON/OFF operation induces the
proper high voltage in the coil
secondary circuit.
