B2302-WIPER MODE SWITCH INPUT CIRCUIT HIGH (SCM)

For a complete wiring diagram refer to Diagrams/Electrical.

- When Monitored:
- With the ignition on.
- Set Condition:
- When the Steering Control Module detects a short/HIGH condition.





Diagnostic Test

1. INTERMITTENT CONDITION

Turn the ignition on.

With the Scan Tool, clear all CCN DTC's.

Turn the Wipers ON then OFF.

With the Scan Tool, read the Wiper DTC's.

Does the Scan Tool read: B2302-WIPER MODE SWITCH INPUT CIRCUIT HIGH?

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.
- Perform the BODY VERIFICATION TEST - VER 1. Body Verification Test

2. MULTIFUNCTION SWITCH

Turn the ignition off.

Using the correct service procedure, remove the Wiper Multi-Function Switch.

Measure the internal resistance of the Multifunction Switch between cavities 7 and 9. Move the switch position from OFF to HIGH while measuring.

OFF = 1581 ohms

DELAY 1 = 695 ohms

DELAY 2 = 463 ohms

DELAY 3 = 323 ohms

DELAY 4 = 232 ohms

DELAY 5 = 169 ohms

LOW = 96 ohms

HIGH = 0 ohms

Is the resistance in each position correct?

Yes

- Replace the Steering Control Module.
- Perform the BODY VERIFICATION TEST - VER 1. Body Verification Test

No

- Replace the Multifunction Switch.
- Perform the BODY VERIFICATION TEST - VER 1. Body Verification Test
