MIC-WIPER SWITCH INPUT CIRCUIT OPEN (CONTINUED)
2.
MULTI- FUNCTION SWITCH
Turn the ignition off.
Disconnect the Multi- Function Switch harness connector.
Ensure that the Multi- Function Switch is in the Off position.
Measure the internal resistance of the Multi- Function Switch between
cavity 2 and cavity 4.
Does the Multi- Function Switch measure more than 5.0 ohms?
Yes
>> Replace the Multi- Function Switch in accordance with the
Service Information.
Perform BODY VERIFICATION TEST - VER 1.
No
>> Go To 3
3.
INTERMITTENT WIPER SWITCH SENSE CIRCUIT OPEN
Turn the ignition off.
Disconnect the Multi- Function Switch harness connector.
Disconnect the Instrument Cluster C4 harness connector.
Measure the resistance of the (W52) Intermittent Wiper Switch Sense
circuit.
Is the resistance above 5.0 ohms?
Yes
>> Repair the (W52) Intermittent Wiper Switch Sense circuit
for an open.
Perform BODY VERIFICATION TEST - VER 1.
No
>> Replace and configure the Instrument Cluster in accor-
dance with the Service Information.

INTERMITTENT CONDITION
Turn the ignition on.
With the DRBIII
T
, clear all MIC DTC’s.
Turn the Wipers ON.
With the DRBIII
T
, read the DTC information.
Does the DRBIII
T
read: Wiper Switch Input Cir-
cuit Short?
Yes
>> Go To 2
No
>> The condition that caused the symptom
is currently not present. Inspect the
related wiring for a possible intermittent
condition. Look for any chafed, pierced,
pinched, or partially broken wires.
