TEST
ACTION
APPLICABILITY
1
Turn the ignition off.
Remove the Wiper On/Off Relay from the IPM.
Using a 12-volt test light connected to ground, probe both Fused B(+) circuits in the
IPM.
NOTE: The test light must illuminate brightly. Compare the brightness to
that of a direct connection to the battery.
Does the test light illuminate brightly at each terminal?
All
Yes
→ Go To 2
No
→ Repair the Fused B(+) circuit for an open.
Perform BODY VERIFICATION TEST - VER 1.
2
Install a substitute relay in place of the Wiper On/Off Relay.
Turn the ignition on.
Turn the wipers on.
Does the system operate correctly?
All
Yes
→ Replace the Wiper On/Off Relay.
Perform BODY VERIFICATION TEST - VER 1.
No
→ Go To 3
3
Turn the ignition off.
Remove the wiper High/Low Relay from the IPM.
Remove the wiper On/Off Relay from the IPM.
Measure the resistance of the Common Relay circuit between the High/Low Relay
and the On/Off relay in the IPM.
Is the resistance below 10.0 ohms?
All
Yes
→ Go To 4
No
→ Repair the Common Relay circuit for an open.
Perform BODY VERIFICATION TEST - VER 1.
4
Install a substitute relay in place of the Wiper Hi/Low Relay.
Turn the ignition on.
Turn the wipers on.
Does the system operate correctly?
All
Yes
→ Replace the Wiper Hi/Low Relay.
Perform BODY VERIFICATION TEST - VER 1.
No
→ Go To 5

Disconnect the IPM C8 harness connector.
Connect a jumper wire between the Wiper Hi/Low Relay Control circuit at the IPM
connector to ground.
Measure the resistance between ground and the Wiper Hi/Low Relay Control circuit.
Is the resistance below 5.0 ohms?
All
Yes
→ Replace the Integrated Power Module.
Perform BODY VERIFICATION TEST - VER 1.
No
→ Repair the Wiper Hi/Low Relay Control circuit for an open.
Perform BODY VERIFICATION TEST - VER 1.

Disconnect the IPM C8 harness connector.
Turn the ignition on.
Measure the voltage of the Wiper Hi/Low Relay Control circuit at the IPM connector.
Is the voltage above 1.0 volt?
All
Yes
→ Repair the Wiper Hi/Low Relay Control circuit for a short to
battery.
Perform BODY VERIFICATION TEST - VER 1.
No
→ Go To 2
2
Install a substitute relay in place of the Wiper Hi/Low Relay.
Turn the ignition on.
