Code No.C1610: AWC Power Supply Electronic Relay Malfunction
 
 
 
 
OPERATION
A relay is incorporated in AWC-ECU, and the power is supplied to the actuator via this relay.
 
 
DIAGNOSIS CODE SET CONDITIONS
This diagnosis code is set when the actuator power supply voltage is less than 6 V while the actuator power supply relay in the AWC-ECU is ON.
 
 
PROBABLE CAUSES
  • Malfunction of AWC-ECU
  • Malfunction of electronic control coupling solenoid
  • Damaged harness wires and connectors
 
 
DIAGNOSIS PROCEDURE
STEP 1. Measure the resistance at the AWC-ECU connector.
(1) Disconnect the connector, and measure at the wiring harness side.
(2) Resistance between AWC-ECU connector terminal SOL+, SOL- and body earth.
OK: No continuity
Is the check result normal?
Go to Step 3.
Go to Step 2.
 
STEP 2. Check the wiring harness between electronic control coupling solenoid connector and AWC-ECU connector terminal SOL+, SOL-.
Check the power supply, earth line for short circuit (for short to the power supply).
Is the check result normal?
Go to Step 3.
Repair the defective connector or the 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.C1610 set?
Replace the AWC-ECU (Refer to ).
Intermittent malfunction (Refer to GROUP 00 - How to Cope with Intermittent Malfunction ).
