High Beam Relay Circuit High

Monitored & Set Condition

1. When Monitored: With ignition On.
2. Set Condition: The BCM detects battery on the high Beam Relay when it is attempting to turn on the High Beams for more than 5 seconds.

Possible Causes:

• Intermittent Condition
• Missing Relay
• Open Fuse
• High Beam Relay
• Body Control Module
• Fused High Beam Relay Output Circuit Open

Testing

1. Turn the ignition on. With the DRBIII(R), clear all BCM DTC's. Turn the High Beams on. With the DRBIII(R), read the DTC information. Does the DRBIII(R) read: HIGH BEAM RELAY CIRCUIT HIGH? If yes, go to next step. If 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 BODY VERIFICATION TEST  .
2. Turn the ignition off. Check the Junction Block to make certain the High Beam Relay is present. Is the High Beam Relay present? If yes, go to next step. If no, replace the missing High Beam Relay. Perform BODY VERIFICATION TEST  .
3. Turn the ignition off. Check the Junction Block High Beam fuses No. 26 and No. 27. Are any of the fuses open? If yes, replace the open fuse 5. Perform BODY VERIFICATION TEST  . If no, go to next step.
4. Turn the ignition off. Install a known good relay in place of the High Beam Relay. Turn the High Beams On. Do the High Beams operate normally? If yes, replace the High Beam Relay. Perform BODY VERIFICATION TEST  . If no, go to next step.
5. Turn the ignition off. Remove the High Beam Relay. Measure the voltage of the Fused B+ circuit of the High Beam Relay. Is the voltage above 10 volts? If yes, replace the Body Control Module. Perform BODY VERIFICATION TEST  . If no, repair the Fused High Beam Relay Output circuit for an open condition. Perform BODY VERIFICATION TEST  .
