16-88spec table

Wiper System ground cause uses RHD-alternate ground points in brackets, ( ): RHD.

Input Test (cont'd)

No.	Terminal	Test condition	Test: desired result	Possible cause (if result is not obtained)
1	BLK	Under all conditions.	Check for continuity to ground: should be continuity.	• Poor ground (G301, G401 [G201, G401]).
2	BLU/WHT1 and BLU/WHT2	Wiper switch OFF or INT and wiper blades in park position.	Check for continuity between the BLU/WHT1 and BLU/WHT2 terminals: should be continuity.	• Faulty wiper switch. • Faulty wiper motor. • An open in the wire.
3	GRN	Ignition switch ON and wiper switch INT	Check for voltage to ground: should be battery voltage.	• Blown No.13 (15A) fuse. • Faulty wiper switch. • An open in the wire.
