TEST
ACTION
APPLICABILITY
1
Turn the ignition off.
Disconnect the Water Cycle Valve harness connector.
Disconnect the Automatic Temperature Control (ATC) C1 harness connector.
Measure the resistance between ground and the Water Cycle Valve Control circuit.
Is the resistance below 10k ohms?
All
Yes
→ Repair the Water Cycle Valve Control circuit for a short to ground.
Perform BODY VERIFICATION TEST - VER 1.
No
→ Go To 2
2
Turn the ignition off.
Disconnect the Water Cycle Valve harness connector.
Disconnect the Automatic Temperature Control (ATC) C1 harness connector.
Measure the resistance between the Water Cycle Valve Control circuit and the
Ground circuit in the Automatic Temperature Control C1 harness connector.
Is the resistance below 10k ohms?
All
Yes
→ Repair the Water Cycle Valve Control circuit for a short to the
Ground circuit.
Perform BODY VERIFICATION TEST - VER 1.
No
→ Go To 3
3
Turn the ignition off.
Disconnect the Water Cycle Valve harness connector.
Disconnect the Automatic Temperature Control (ATC) C1 harness connector.
Measure the resistance between the Water Cycle Valve Control circuit and the Sensor
Ground circuit in the Automatic Temperature Control C1 harness connector.
Is the resistance below 10k ohms?
All
Yes
→ Repair the Water Cycle Valve Control circuit for a short to the
Sensor Ground circuit.
Perform BODY VERIFICATION TEST - VER 1.
No
