COMPASS/MINI-TRIP COMPUTER
Symptom:
*OUTSIDE TEMPERATURE DISPLAY INACCURATE OR INOPERA-
TIVE
POSSIBLE CAUSES
AMBIENT TEMPERATURE SENSOR
COMPASS/MINI-TRIP COMPUTER
TEST
ACTION
APPLICABILITY
1
NOTE: Ensure that the CMTC is communicating on the PCI Bus before
proceeding with this test.
NOTE: The Ambient Temperature Sensor is hardwired to the PCM. Diag-
nose and repair any PCM DTCs before proceeding with this test.
Turn the ignition off.
Disconnect the Ambient Temperature Sensor harness connector.
Measure the resistance of the Ambient Temperature Sensor using the following
temperature/resistance values:
10°C (50°F) Sensor Resistance = 17.99 - 21.81 Kilohms
20°C (68°F) Sensor Resistance = 11.37 - 13.61 Kilohms
25°C (77°F) Sensor Resistance = 9.12 - 10.88 Kilohms
30°C (86°F) Sensor Resistance = 7.37 - 8.75 Kilohms
40°C (104°F) Sensor Resistance = 4.90 - 5.75 Kilohms
50°C (122°F) Sensor Resistance = 3.33 - 3.88 Kilohms
Is the Ambient Temperature Sensor resistance measurement between the min/max
specifications?
All
Yes
→ Test Complete.
No
→ Replace the Ambient Temperature Sensor. NOTE: After any
repair for an Ambient Temperature Sensor problem, the vehicle
must be driven over 3 miles above 25 MPH to update the CMTC
display.
Perform BODY VERIFICATION TEST - VER 1.

COMPASS/MINI-TRIP COMPUTER
Symptom:
*DECKLID AJAR CIRCUIT OPEN
POSSIBLE CAUSES
DECKLID RELEASE SOLENOID/AJAR SWITCH CASE GROUND OPEN
INTERMITTENT CONDITION
DECKLID RELEASE SOLENOID/AJAR SWITCH
DECKLID AJAR SWITCH SENSE CIRCUIT OPEN
BODY CONTROL MODULE INTERNAL MALFUNCTION
TEST
ACTION
APPLICABILITY
1
Open the Decklid.
With the DRBIII
t in Inputs/Outputs, read the DECKLID AJAR SW state.
Does the DRBIII
t display CLOSED?
All
Yes
→ The condition that caused this symptom is currently not present.
Inspect the related wiring harness for a possible intermittent
condition. Look for any chafed, pierced, pinched or partially
broken wires.
Perform BODY VERIFICATION TEST - VER 1.
No
→ Go To 2
2
Disconnect the Decklid Ajar switch connector.
Using a 12-volt Test Light connected to 12-volts, test the Case Ground for continuity.
Does the light illuminate?
All
Yes
→ Go To 3
No
→ Repair the Case Ground for an open.
Perform BODY VERIFICATION TEST - VER 1.
3
Disconnect the Decklid Ajar Switch connector.
With the DRBIII
t in Inputs/Outputs, read the DECKLID AJAR SW state.
Connect a jumper wire between Sense circuit and body ground.
Does the DRBIII
t display DECKLID AJAR SW: CLOSED?
All
Yes
→ Replace the Decklid Release Solenoid/Ajar Switch.
Perform BODY VERIFICATION TEST - VER 1.
No
→ Go To 4
4
Disconnect the Body Control Module C4 harness connector.
Disconnect the Decklid Ajar Switch harness connector.
Measure the resistance of the Sense circuit.
Is the resistance below 5.0 ohms?
All
Yes
→ Replace the Body Control Module.
Perform BODY VERIFICATION TEST - VER 1.
No
→ Repair the Decklid Ajar Switch Sense circuit for an open.
Perform BODY VERIFICATION TEST - VER 1.
