PINPOINT TEST A : THE AUDIO UNIT IS INOPERATIVE/DOES NOT
OPERATE CORRECTLY

TEST CONDITIONS

DETAILS/RESULTS/ACTIONS

A1: CHECK FOR POWER TO THE AUDIO UNIT

Disconnect Audio Unit C2ME03A.

1

Ignition switch in position I.

2

Measure the voltage between the audio unit
C2ME03A pin 15, circuit SBP06D (BN/RD), harness

side and ground, and between the audio unit
C2ME03A pin 16, circuit CDC33C (VT/GN), harness
side and ground.

3

Are the voltages greater than 10 volts?
Yes

GO to A2

.

No

REPAIR circuit SBP06D (BN/RD) or circuit CDC33C
(VT/GN). TEST the system for normal operation.

A2: CHECK THE AUDIO UNIT GROUND CIRCUITS FOR GROUND

Ignition switch in position 0.

1

Measure the resistance between the audio unit
C2ME03A pin 11, circuit GD103C (BK/BU), harness

side and ground, and between the audio unit
C2ME03A pin 12, circuit GD103A (BK/BU), harness
side and ground.

2

Are the resistances less than 1 ohm?
Yes

INSTALL a new audio unit.
REFER to: Audio Unit (415-01 Information and
Entertainment System, Removal and Installation).
TEST the system for normal operation.

No

REPAIR circuit GD103C (BK/BU) or circuit GD103A
(BK/BU). TEST the system for normal operation.

PINPOINT TEST B : POOR RECEPTION

NOTE: The secondary antenna cable amplifier to left-rear quarter glass wiring harness is

polarised (labelled A and B) at the rear quarter glass end. The polarisation of these
connectors should be checked before proceeding as an incorrect connection may cause
poor or no reception.
NOTE: The performance of the secondary antenna may be affected if windshield adhesive
comes into contact with the antenna connections in the glass. Check the connections are
free from windshield adhesive before proceeding.

TEST CONDITIONS

DETAILS/RESULTS/ACTIONS

B1: CHECK THE PRIMARY ANTENNA CABLE SHIELD

Ignition switch in position 0.

1

Disconnect the antenna cable from the audio unit.

2

Measure the resistance between the antenna cable
ground connector (shield), and ground.

3

Is the resistance less than 1 ohm?
Yes

GO to B2

.

No

CLEAN and TIGHTEN the antenna base connection
to the body. If the concern persists, INSTALL a new
antenna cable. TEST the system for normal
operation.

B2: CHECK THE PRIMARY ANTENNA CENTER CONDUCTOR FOR OPEN CIRCUIT

Remove the antenna mast.

1

Measure the resistance of the center conductor
between the ends of the antenna cable.

2

Is the resistance less than 1 ohm?
Yes

GO to B3

.

No

INSTALL a new antenna cable. TEST the system for
normal operation.

B3: CHECK THE PRIMARY ANTENNA CABLE FOR SHORT

Measure the resistance between the antenna
center conductor and the antenna ground (shield).
