Diagnostic Test

1.INTERMITTENT CONDITION






Does the scan tool display active: B1630-RIGHT LOW BEAM CONTROL CIRCUIT HIGH?

Yes
  • Go To 2


No
  • The condition that caused this symptom is currently not present. Check for an intermittent condition by inspecting the related wiring harness for chafed, pierced, pinched, and partially broken wires. Also, inspect the related connectors for broken, bent, pushed out, spread, corroded, or contaminated terminals. Repair as necessary.
  • Perform the BODY VERIFICATION TEST - VER 1. (Refer to 8 - ELECTRICAL/ELECTRONIC CONTROL MODULES - STANDARD PROCEDURE)

2.CHECK (Z904) GROUND CIRCUITS





Does the test light illuminate brightly on each ground circuit?

Yes
  • Go To 4


No
  • Go To 3

3.(Z904) GROUND CIRCUIT OPEN



Is the resistance below 10.0 ohms?

Yes


No

4.CHECK (L44) RIGHT LOW BEAM CONTROL CIRCUIT




Does the test light illuminate brightly with the headlamps switch turned on, and shut off with the headlamps turned off?

Yes


No
  • Go To 5

5.(L44) RIGHT LOW BEAM CONTROL CIRCUIT OPEN







Is the resistance below 10.0 ohms?

Yes
  • Go To 6


No

6.(L44) RIGHT LOW BEAM CONTROL CIRCUIT SHORTED TO VOLTAGE






Is there any voltage present?

Yes


No
