7
Turn the ignition off.
Remove the Headlamp Delay Relay from the junction block.
Remove the Body Control Module from the junction block.
Measure resistance of the Headlamp Delay Relay control circuit.
Is the resistance below 5.0 ohms?
All
Yes
→ Replace the Body Control Module.
Perform BODY VERIFICATION TEST - VER 1.
No
→ Replace the Junction Block.
Perform BODY VERIFICATION TEST - VER 1.
8
Remove and test the PDC Fuse 4.
Is the Fuse open?
All
Yes
→ Go To 9
No
→ Repair the open Fused B+ circuit between the Headlamp Delay
Relay connector in the junction block and the PDC Fuse 4
connector.
Perform BODY VERIFICATION TEST - VER 1.
9
Remove Fuse 4 from the PDC
Measure the resistance of the Fused B+ circuit in the fuse connector to ground.
Is the resistance below 5.0 ohms?
All
Yes
→ Repair the Fused B+ circuit for a short to ground.
Perform BODY VERIFICATION TEST - VER 1.
No
→ Replace the fuse and retest the system.
Perform BODY VERIFICATION TEST - VER 1.

Symptom:
A/C BLEND DOOR INPUT SHORTED TO BATTERY - MTC
When Monitored and Set Condition:
A/C BLEND DOOR INPUT SHORTED TO BATTERY - MTC
When Monitored:
With the engine running.
Set Condition:
The BCM reads the signal from the A/C - Heater Control blend request
and positions the blend door accordingly. If the voltage on this pin exceeds 90% of ignition
voltage, the DTC will set, and the BCM will place the blend door in a default position.
POSSIBLE CAUSES
CONTROL HEAD - TEMPERATURE SELECT SIGNAL SHORTED TO VOLTAGE
TEMPERATURE SELECT SIGNAL CIRCUIT SHORTED TO VOLTAGE
BODY CONTROL MODULE - TEMPERATURE SELECT SIGNAL SHORTED TO VOLTAGE
TEST
ACTION
APPLICABILITY
1
With the DRBIII
t, record and erase Body Computer DTC’s.
Turn the ignition off.
Disconnect the A/C - Heater Control C1 harness connector.
Turn the ignition on.
Measure the voltage of the Temperature Select Signal circuit.
Is the voltage above 0.3 volts?
All
Yes
→ Go To 2
No
→ Replace the A/C - Heater Control in accordance with the Service
Information.
Calibration must be performed after repair/replacement is com-
pleted.
Perform BODY VERIFICATION TEST - VER 1.
2
Turn the ignition off.
Disconnect the A/C - Heater Control C1 harness connector.
Disconnect the Body Control Module C2 harness connector.
Turn the ignition on.
Measure the voltage of the Temperature Select Signal circuit.
Is there any voltage present?
All
Yes
→ Repair the Temperature Select Signal circuit for a short to
voltage.
Calibration must be performed after repair/replacement is com-
pleted.
Perform BODY VERIFICATION TEST - VER 1.
No
→ Replace and program the Body Control Module in accordance
with the Service Information.
Calibration must be performed after repair/replacement is com-
pleted.
Perform BODY VERIFICATION TEST - VER 1.

HEATING & A/C
Symptom:
A/C BLEND DR INPUT OPEN/SHORT TO GROUND - MTC
When Monitored and Set Condition:
A/C BLEND DR INPUT OPEN/SHORT TO GROUND - MTC
When Monitored:
With the engine running.
Set Condition:
The BCM reads the signal from the A/C - Heater Control blend request
and positions the blend door accordingly. If the voltage on this pin is below 0.1 volts, the
DTC will set, and the BCM will place the blend door in a default position.
POSSIBLE CAUSES
ADDITIONAL CODE(S) PRESENT
FUSED IGNITION SWITCH OUTPUT CIRCUIT OPEN
TEMPERATURE SELECT SIGNAL CIRCUIT SHORTED TO GROUND
TEMPERATURE SELECT SIGNAL CIRCUIT SHORTED TO SENSOR GROUND
TEMPERATURE SELECT SIGNAL CIRCUIT OPEN
CONTROL HEAD - TEMPERATURE SELECT SIGNAL OPEN/SHORTED TO GROUND
BODY CONTROL MODULE - TEMPERATURE SELECT SIGNAL OPEN/SHORTED TO GROUND
TEST
ACTION
APPLICABILITY
1
Turn the ignition on.
With the DRBIII
t read the Body Computer DTCs.
Are Mode Door Input Open/STG and Blend Door Input Open/STG DTCs present?
(May set TCM Msg Not Recd).
All
Yes
→ If JB Fuse 11 is open, check for short to ground in Junction Block,
BCM, and Fused Ign Sw Output Ckt. If JB Fuse 11 is not open,
check for an open between JB Fuse 11 Pin 19, and JB C7-10
harness connector, and splice 210 in Fused Ign Sw Output Ckt.
Calibration must be performed after repair/replacement is com-
pleted.
Perform BODY VERIFICATION TEST - VER 1.
No
→ Go To 2
2
Turn the ignition off.
Disconnect the A/C - Heater Control C1 harness connector.
Turn the ignition on.
Using a 12-volt test light connected to ground, probe the Fused Ignition Switch
Output circuit.
Is the test light illuminated?
All
Yes
→ Go To 3
No
→ Repair the Fused Ignition Switch Output circuit for an open.
Calibration must be performed after repair/replacement is com-
pleted.
