Diagnostic Test
1. INTERMITTENT CONDITIONTurn 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: B230B-REAR WIPER SWITCH INPUT CIRCUIT HIGH (SCM)?
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. (Refer to 8 - ELECTRICAL/ELECTRONIC CONTROL MODULES - STANDARD PROCEDURE)
2. WIPER 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 4 and 5. Move the switch into each position while measuring.
OFF = 1045 ohms
INTERMITTENT = 382 ohms
WIPE = 174 ohms
WASH = 0 ohms
Is the resistance in each position correct?
Yes
- Replace the Steering Control Module in accordance with the service information.
- Perform the BODY VERIFICATION TEST — VER 1. (Refer to 8 - ELECTRICAL/ELECTRONIC CONTROL MODULES - STANDARD PROCEDURE)
No
- Replace the Multifunction Switch in accordance with the service information.
- Perform the BODY VERIFICATION TEST — VER 1. (Refer to 8 - ELECTRICAL/ELECTRONIC CONTROL MODULES - STANDARD PROCEDURE)
