Diagnosis and Testing

Refer to Wiring Diagrams Section 413-09, for schematic and connector information.

Inspection and Verification

  1. Verify the customer concern.
  1. Visually inspect for obvious signs of mechanical or electrical damage.

Pinpoint Tests

PINPOINT TEST A : THE HEADLAMPS ON REMINDER CHIME IS INOPERATIVE/DOES NOT OPERATE CORRECTLY
TEST CONDITIONS DETAILS/RESULTS/ACTIONS
A1: CHECK CIRCUIT 29S-WA9 (OG/BK) FOR VOLTAGE
1
Disconnect Lights-ON-Warning Buzzer C147.
2
Place the headlamp switch in the LOW BEAM position.

3
Measure the voltage between the lights-ON-warning buzzer C147 pin 5, circuit 29S-WA9 (OG/BK), harness side and ground.

Is the voltage greater than 10 volts?
Yes
GO to A6.
No
GO to A2.
A2: CHECK CIRCUIT 29S-WA9 (OG/BK) FOR OPEN

1
Measure the resistance between the lights-ON-warning buzzer C147 pin 5, circuit 29S-WA9 (OG/BK), and the number 6 fuse holder in the CJB.

Is the resistance less than 5 ohms?
Yes
GO to A3.
No
REPAIR the circuit. TEST the system for normal operation.
A3: CHECK CJB FOR OPEN
1
Disconnect Fuse 6.

2
Measure the resistance between the electrical connectors for fuse 6 within the CJB.

Is the resistance less than 5 ohms?
Yes
GO to A4.
No
INSTALL a new CJB. TEST the system for normal operation.
A4: CHECK CIRCUIT 29S-DB7 (OG/YE) FOR OPEN
1
Disconnect Headlamp Switch C102A.

2
Measure the resistance between the headlamp switch C102A pin 7, circuit 29S-DB7 (OG/YE), and the number 6 fuse holder in the CJB.

Is the resistance less than 5 ohms?
Yes
GO to A5.
No
REPAIR the circuit. TEST the system for normal operation.
A5: TEST THE HEADLAMP SWITCH OUTPUT

1
Measure the voltage between the headlamp switch C102A pin 7, circuit 29S-DB7 (OG/YE), harness side and ground.

Is the voltage greater than 10 volts?
Yes
GO to A6.
No
INSTALL a new headlamp switch. TEST the system for normal operation.
A6: CHECK THE DRIVER SIDE INTERIOR LAMP SWITCH CIRCUIT FOR OPEN
1
Disconnect Driver Side Interior Lamp Switch C124 (LHD) or C125 (RHD).

2
Measure the resistance between:
  • (LHD) the lights-ON-warning buzzer C147 pin 1, circuit 31S-LC9 (BK/RD) and the driver side interior lamp switch C124 pin 1, harness side.
  • (RHD) the lights-ON-warning buzzer C147 pin 1, circuit 31S-LC21 (BK/GN) and the driver side interior lamp switch C125 pin 1, harness side.

Is the resistance less than 5 ohms?
Yes
Install a new lights-ON-warning buzzer. TEST the system for normal operation.
No
REPAIR circuit 31S-LC9 (BK/RD) or circuit 31S-LC9 (BK/GN). TEST the system for normal operation.
