Diagnosis and Testing

Refer to Wiring Diagrams Section 413-00, for schematic and connector
information.

General Equipment

Instrument Cluster and Dimmable Backlighting

The dimmable illumination utilizes light emitting diodes (LEDs) and bulb(s).

The following dimmable components are backlit using LEDs only:

transmission control lever
heater control panel
audio unit
navigation system display module
instrument cluster
climate control module
hazard switch
traction control system disable switch
right-hand and left-hand heated front seat switch(es)

Inspection and Verification

1. 1. Verify the customer concern.

2. 2. Visually inspect for obvious signs of mechanical or electrical damage.

Visual Inspection Chart

3. 3. If an obvious cause for an observed or reported concern is found, correct the cause

(if possible) before proceeding to the next step

4. 4. If the cause is not visually evident, verify the symptom and refer to the Symptom

Chart.

PINPOINT TEST A : THE CIGAR LIGHTER ILLUMINATION IS INOPERATIVE

TEST CONDITIONS

DETAILS/RESULTS/ACTIONS

A1: CHECK CIRCUIT CLN17S (BN) FOR VOLTAGE

Disconnect Cigar Lighter C2DC07-B.

1

Ignition switch in position II.

2

Make sure that the illumination dimmer switch is in
the full illumination position.

3

Place the headlamp switch in the ON position.

4

Measure the voltage between the cigar lighter
C2DC07-B pin 1, circuit CLN17S (BN), harness side

and ground.

5

Is the voltage greater than 10 volts?
Yes

GO to A2

.

No

REPAIR the circuit CLN17S (BN) or circuit CLN17G
(BN) as necessary. TEST the system for normal
operation.

A2: CHECK CIRCUIT GD138AZ (BK/WH) FOR OPEN

Connect Cigar Lighter C2DC07-B.

1

Disconnect Cigar Lighter C2DC07-A.

2

Measure the resistance between the cigar lighter
C2DC07-A pin 1, circuit GD138AZ (BK/WH), harness

side and ground.

3

Is the resistance less than 5 ohms?
Yes

INSTALL a new cigar lighter. TEST the system for
normal operation.

No

REPAIR circuit GD138AZ (BK/WH) or circuit GD138AL
(BN/WH) as necessary. TEST the system for normal
operation.

PINPOINT TEST B : THE HAZARD SWITCH ILLUMINATION IS
INOPERATIVE

TEST CONDITIONS

DETAILS/RESULTS/ACTIONS

B1: CHECK CIRCUIT CLS38A (VT/WH) FOR VOLTAGE

Disconnect Hazard Switch C2LS32.

1

Ignition switch in position II.

2

Make sure that the illumination dimmer switch is in
the full illumination position.

3

Place the headlamp switch in the ON position.

4

Measure the voltage between the hazard switch
C2LS32 pin 5, circuit CLS38A (VT/WH), harness side

and ground.

5

Is the voltage greater than 10 volts?
Yes

GO to B2

.

No

REPAIR the circuit. TEST the system for normal
operation.

B2: CHECK CIRCUIT GD133CF (BK) FOR OPEN

Ignition switch in position 0.

1

Measure the resistance between hazard switch
C2LS32 pin 4, circuit GD133CF (BK), harness side

and ground.

2
