Diagnostic procedure
No DTC indicates
Engine does not start to run even though all engine and electrical system are OK, and no DTC appears.
1. 12V power is not supplied to ICU.
Check engine light
Is blinking at 2Hz.ECM or electrical
unit wiring check No
Yes Yes
Starter is not rotated
By correct key at all.Check DTC with Tech 2
12V power is not
supplied to ICU
Repair 12V circuitICU power supply turns off when both +B line
and ignition switch line turn off.
ICU
No.1 Pin
No.2 Pin+B
Ignition SWCheck both wiring systems for continuity.
No
2. Engine does not start after steering assembly is repaired.
Check if connector for Antenna coil circuit at steering shaft is correct, or missing connection.
If not correct, replace the steering assy with corrector.
