APPLICABILITY
1
Turn the ignition off.
Disconnect the ATC C2 harness connector.
Turn the ignition on.
Measure the voltage between the applicable Door Driver (A) circuit and ground.
Measure the voltage between the applicable Door Driver (B) circuit and ground.
Is the voltage above 0.2 volts on either circuit?
All
Yes
→ Repair the door driver circuit with voltage above 0.2 volts for a
short to voltage.
Perform BODY VERIFICATION TEST - VER 1.
No
→ Go To 2
2
Turn the ignition off.
Disconnect the ATC C2 harness connector.
Measure the resistance between ground and the applicable Door Driver (A) circuit.
Measure the resistance between ground and the applicable Door Driver (B) circuit.
Is the resistance below 10K ohms on either circuit?
All
Yes
→ Repair the door driver circuit with resistance below 10K ohms for
a short to ground.
Perform BODY VERIFICATION TEST - VER 1.
No
→ Go To 3
3
Turn the ignition off.
Disconnect the ATC C2 harness connector.
NOTE: Do NOT measure the resistance between the Door Driver circuits
that connect to the same actuator.
Measure the resistance between the applicable Door Driver (A) circuit and each of the
remaining Door Driver circuits.
Measure the resistance between the applicable Door Driver (B) circuit and each of the
remaining Door Driver circuits.
Is the resistance below 10K ohms on any of the circuits?
All
Yes
→ Repair the door driver circuits with a resistance below 10K ohms
for a short together.
Perform BODY VERIFICATION TEST - VER 1.
No
→ Go To 4
4
Turn the ignition off.
Disconnect the ATC C2 harness connector.
Measure the resistance between the applicable actuator’s Door Driver (A) circuit and
Door Driver (B) circuit.
Is the resistance below 30.0 ohms?
All
Yes
→ Go To 5
No
→ Go To 6
