Code No. C1628: Abnormal Electronic Control Coupling Solenoid Current
 
 
 
 
OPERATION
The AWC-ECU monitors the current value of the electronic control coupling solenoid.
 
 
DIAGNOSIS CODE SET CONDITIONS
This diagnosis code is set when the abnormality below is detected:
  • By the monitored electronic control solenoid current, the AWC-ECU judges the undercurrent failure.
  • By the monitored electronic control solenoid current, the AWC-ECU judges the overcurrent failure.
  • The AWC-ECU judges the monitor circuit failure.
 
 
PROBABLE CAUSES
  • Malfunction of electronic control coupling solenoid
  • Damaged harness wires and connectors
  • Malfunction of AWC-ECU
 
 
DIAGNOSIS PROCEDURE
STEP 1. Check of open circuit, and short circuit in SOL+ line between electronic control coupling solenoid connector and AWC-ECU connector.
Is the check result normal?
Go to Step 2.
Repair the connector(s) or wiring harness.
 
STEP 2. Check of open circuit, and short circuit in SOL- line between electronic control coupling solenoid connector and AWC-ECU connector.
Is the check result normal?
Go to Step 3.
Repair the connector(s) or wiring harness.
 
STEP 3. Check of the electronic control coupling solenoid
Refer to .
Is the check result normal?
Go to Step 4.
Replace the electronic control coupling (Refer to ).
 
STEP 4. Check whether the diagnosis code is set again.
Is diagnosis code No.C1628 set?
Replace the AWC-ECU (Refer to ).
Intermittent malfunction (Refer to GROUP 00 - How to Cope with Intermittent Malfunction ).
