Test D: The Intermittent Wiper Speed Does Not Operate Correctly
PINPOINT TEST D: THE INTERMITTENT WIPER SPEED DOES NOT OPERATE CORRECTLYD1-D3:
D3-D5:
Normal Operation
Under normal operation, when any wiper mode except OFF is selected, the multi-function switch provides a combination of grounds to the smart junction box (SJB) through circuits 61 (YE/RD), 63 (RD), 65 (DG) and 680 (LB/OG). The SJB interprets this ground combination to determine the desired wiper mode.
Possible Causes
- An open in circuit 61 (YE/RD), 63 (RD), 65 (DG) or 680 (LB/OG)
- A short to ground in circuit 61 (YE/RD), 63 (RD), 65 (DG) or 680 (LB/OG)
- A short together in circuit 61 (YE/RD), 63 (RD), 65 (DG) or 680 (LB/OG)
- Multi-function switch
- Smart junction box (SJB)
