B1630

B1630-RIGHT LOW BEAM CONTROL CIRCUIT HIGH



- When Monitored:
Continuously.

- Set Condition:
When the Totally Integrated Power Module (TIPM) detects a HIGH condition.





1. INTERMITTENT CONDITION
1. Turn the ignition on.
2. With the scan tool, clear all DTC's.
3. Turn the Headlamps on.
4. With the scan tool, read DTC's.

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. Body Verification Test

2. CHECK (L910) RIGHT HEADLAMP RETURN SIGNAL
1. Turn the ignition off.
2. Disconnect the Right Low Beam Lamp harness connector.
3. With a 12-volt test light connected to 12-volts, probe the (L910) right headlamp return signal circuit.

Does the test light illuminate brightly on each ground circuit?

Yes

- Go To 4

No

- Go To 3

3. (L910) RIGHT HEADLAMP RETURN SIGNAL
1. Measure the resistance of the (L910) right headlamp return signal circuit at the Right Low Beam harness connector.

Is the resistance below 10.0 ohms?

Yes

- Replace the Inoperative bulb.
- Perform the BODY VERIFICATION TEST - VER 1. Body Verification Test

No

- Repair the (L910) right headlamp return signal circuit for an open.
- Perform the BODY VERIFICATION TEST - VER 1. Body Verification Test

4. CHECK (L44) RIGHT LOW BEAM CONTROL CIRCUIT
1. Turn the ignition on.
2. With a 12-volt test light connected to ground, check the (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

- Replace the Inoperative bulb.
- Perform the BODY VERIFICATION TEST - VER 1. Body Verification Test

No

- Go To 5

5. (L44) RIGHT LOW BEAM CONTROL CIRCUIT OPEN




1. Turn the ignition off.
2. Disconnect the TIPM C3 harness connector.
3. Measure the resistance of the (L44) Right Low Beam Control circuit between the Right Low Beam harness connector and the TIPM C3 harness connector.

Is the resistance below 10.0 ohms?

Yes

- Go To 6

No

- Repair the (L44) Right Low Beam Control circuit for an open.
- Perform the BODY VERIFICATION TEST - VER 1. Body Verification Test

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




1. Turn the ignition on.
2. Measure for voltage on the (L44) Right Low Beam Control circuit.

Is there any voltage present?

Yes

- Repair the (L44) Right Low Beam Control circuit for a short to voltage.
- Perform the BODY VERIFICATION TEST - VER 1. Body Verification Test

No

- Replace the Totally Integrated Power Module (TIPM).
- Perform the BODY VERIFICATION TEST - VER 1. Body Verification Test
