1. GENERAL INFORMATION
This Section describes the service and testing procedures for the wiper and washer systems as well as the
horns fitted to MY 2003 VY Series and V2 Series II vehicles.
A new one piece plenum cover is fitted to Sedan, Wagon and Utility vehicles. The front washer nozzles are
incorporated in the plenum cover. Coupe vehicles retain the previous two piece plenum cover and have the
washer nozzles mounted in the hood assembly .
A single washer reservoir and pum p is used for all m odels. W agon vehicles, which have a rear washer for the
liftgate, have a dual outlet pump. To feed fluid to the rear washer nozzle, the polarity is reversed to the pump
motor, making it spin in the opposite direction, and forcing fluid to the rear washer nozzle.
All models not having optional trumpet horns, are fitted with a high-note horn, located behind the front bumper
fascia on the right hand side. Vehicles fitted with dual trumpet horns, have the low note horn fitted behind the
front bumper fascia on the left hand side of the vehicle.
A theft-deterrent horn is mounted in the rear of the engine compartment on the left hand side and is controlled by
the Body Control Module. This Section c overs the r em oval and testing of the horn, but f or mor e inform ation and
testing of the theft-deterrent horn, refer to Section 12J, BODY CONTROL MODULE.

assembly operation, being 0 volts, below 9 volts, between 9 and 11 volts, or above 11 volts.
NOTE: If there is a fault in the horn ass embly syst em, and the following test proves that the syst em is serviceable,
refer to Section 12J, BODY CONTROL MODULE.
Test Description
The following numbers refer to the Steps in the diagnostic chart.
1. Checks the voltage supplied to the horn assembly as follow:
• Checks if the system operates correctly, with a normal voltage reading on the multimeter of 9 to 11 volts.
• Checks if there is no voltage reading on the multimeter.
• Chec ks if there is a low voltage reading on the multim eter above 0 volt and below 9 volts. Is olates whether
the horn assembly is at fault.
• Checks if there is a high voltage reading on the multimeter above 11 volts, caused by a faulty horn
assembly.
2. Chec ks whether the relay R8 on the engine compar tment f use and relay panel assembly is serviceable. Isolates
whether the relay is the fault affecting the battery power circuit supplying the horn assembly.
3. Checks the circuit continuity between the connector coil steering wheel inflatable restraint module X116 – X1
pin 6 and pin 5. Isolates whether the connector coil steering wheel inflatable restraint module X116 and/or the
contact steering wheel horn S7 are at fault.
4. Checks the circuit continuity between contact steering wheel S7 – X1 pin A and pin B. Isolates whether the
contact s teering wheel horn S7 is serviceable or the c onnector coil steer ing wheel inflatable res traint module is
at fault.
5. Checks the circuit continuity between the connector coil steering wheel inflatable restraint module X116 – X1
pin 6 and the harness connector S7 – X1 pin A, then between X116 – X1 pin 5 and S7 – X1 pin B. Isolates
whether the contact steering wheel horn S7 has to be replaced in conjunction with the connector coil steering
wheel inflatable restraint module X116.
6. Check s that ther e is battery voltage through the harness c onnector X 116 – X1 pin 6 and pin 5. Isolates whether
there is a fault in circuit 28, 151, or 1240.
7. Checks that battery voltage is delivered to the harness connector B9 – X1. Isolates whether there is a fault in
the horn assembly, or in circuit 29 or 1240.

Go to Step 6. Go to Step 4.
4. 1. Remove the steering wheel inflatable restraint
module, refer to Section 12M, OCCUPANT
PROTECTION SYSTEM.
2. Probe connector S7 – X1 pin A and S7 – X1 pin B on
the steering wheel inflatable restraint module.
3. Press the steering wheel horn contact to activate the
horn assembly.
Is there continuity?
Replace the connector
coil steering wheel
inflatable restraint
module, refer to
Section 12M,

PROTECTION
SYSTEM.
Go to Step 5.
5. 1. Probe the connector coil steering wheel inflatable
restraint module X116 – X1 pin 6 and the harness
connector S7 – X1 pin A.
2. Probe the connector coil steering wheel inflatable
restraint module X116 – X1 pin 5 and the harness
connector S7 – X1 pin B.
Is there continuity?
Replace the steering
wheel inflatable restraint
module, refer to
Section 12M,
