Diagnostic Test
1. INTERMITTENT CONDITION
Turn the ignition on.
With the Scan Tool, clear all TIPM DTC's.
Turn the Headlamps on.
With the Scan Tool read the DTC information.
Q: Does the Scan Tool read: B1630-RIGHT LOW BEAM CONTROL CIRCUIT HIGH?
YES: Go To 2
NO: The condition that caused the symptom is currently not present. Inspect the related wiring for a possible intermittent condition. Look for any chafed, pierced, pinched, or partially broken wires. Perform the BODY VERIFICATION TEST - VER 1. Body Verification Test
2. RIGHT LOW BEAM BULB
Turn the ignition off.
Inspect the Right Low Beam Bulb Assembly.
Q: Is the inoperative bulb OK?
YES: Go To 3
NO: Replace the Inoperative bulb. Perform the BODY VERIFICATION TEST - VER 1. Body Verification Test
3. (L44) RIGHT LOW BEAM CONTROL CIRCUIT OPEN
Turn the ignition off.
Disconnect the TIPM C5 harness connector.
Disconnect the Right Low Beam Lamp harness connector.
Measure the resistance of the (L44) Right Low Beam Control circuit.
Q: Is the resistance above 5.0 ohms?
YES: Repair the (L44) Right Low Beam Control circuit for an open condition. 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
4. (L44) RIGHT LOW BEAM CONTROL CIRCUIT SHORTED TO VOLTAGE
Turn the ignition off.
Disconnect the TIPM C5 harness connector.
Disconnect the Right Low Beam Lamp harness connector.
Turn the ignition on.
Measure for voltage on the (L44) Right Low Beam Control circuit.
Q: Is the voltage above 10.0 volts?
YES: Repair the (L44) Right Low Beam Control circuit for a short to voltage condition. 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
