ACTION

APPLICABILITY

1

Turn the ignition on.
With the DRB, read the active ATC DTCs.
Is the FRONT MODE DOOR NOT RESPONDING DTC set?

All

Yes

→ Return to the symptom list and choose the symptom.

With the DRBIII

t, reset the ATC after repair is complete.

Perform BODY VERIFICATION TEST - VER 1.

While monitoring the test light, turn the mode control knob to each position.
Note: Observe test light for approximately 30 seconds.
Does the test light start to flash and stay flashing?

All

Yes

→ Go To 3

No

→ Replace the ATC.

With the DRBIII

t, reset the ATC after repair is complete.

Perform BODY VERIFICATION TEST - VER 1.

3

Remove the Mode Door Actuator. Rotate the mode doors (doors only). Note: These
should rotate approximately 45 degrees from stop to stop.
Do the mode doors move smoothly in both directions?

All

Yes

→ Replace the Mode Door Actuator.

With the DRBIII

t, reset the ATC after repair is complete.

Perform BODY VERIFICATION TEST - VER 1.

No

→ Repair or replace the mode door as necessary.

With the DRBIII

t, reset the ATC after repair is complete.

Perform BODY VERIFICATION TEST - VER 1.

CAUTION: The work area ambient temperature must be above 15.6°C (60°F)
to test A/C system operation.
Start the engine.
Turn the A/C off.
Turn the Blower on high. Allow the blower to run for 5 minutes to ensure that the
Evaporator Temperature Sensor temperature is above 12.7°C (55°F).
With the DRBIII

t, actuate the Cooldown Test.

Does the DRBIII

t display: Cooldown Test Too Cold To Start?

All

Yes

→ Go To 2

No

→ Perform additional testing as necessary.

Perform BODY VERIFICATION TEST - VER 1.

CAUTION: The work area ambient temperature must be above 15.6°C (60°F)
to test A/C system operation.
Turn the ignition on.
With the DRBIII

t, read ATC DTCs.

Does the DRBIII

t display any ATC DTCs?

All

Yes

→ Return to the symptom list and choose the symptom(s). After the

repair is complete, with the DRBIII

t, erase the DTC(s). Cycle the

ignition switch. With the DRBIII

t, reset the ATC. With the

DRBIII

Turn the ignition off.
Disconnect the Evaporator Temperature Sensor harness connector.
Turn the ignition on.
With the DRBIII

t in Sensor Display, read the Evaporator Temperature Sensor

voltage.
Is the voltage above 4.9 volts?

All

Yes

→ Go To 5

No

→ Go To 6

5

Turn the ignition off.
Disconnect the Evaporator Temperature Sensor harness connector.
Connect a jumper wire between the Evaporator Temperature Sensor Signal circuit
and the Sensor Ground circuit at the Evaporator Temperature Sensor harness
connector.
Turn the ignition on.
With the DRBIII

t in Sensor Display, read the Evaporator Temperature Sensor

voltage.
Is the voltage 0.0 volts?

All

Yes

→ Replace the Evaporator Temperature Sensor in accordance with

the Service Information. After the repair is complete, with the
DRBIII

t, reset the ATC. With the DRBIIIt, accuate the Cooldown

Test.
