1. Yes: INSTALL a new SOD-R or SOD-L . REFER to «Removal and Installation»(ref-356018-S14146651352010013000000) . TEST the system for normal operation.
2. No: The system is operating correctly at this time. The concern may have been caused by an intermittent problem.

Pinpoint Test I: The Left Or Right Exterior Mirror Blind Spot Information System (BLIS™)/Cross Traffic Alert (CTA) LED Appears Dim Or Does Not Illuminate With No DTC Or Message In The Instrument Panel Cluster (IPC) Message Center Present

Refer to the appropriate SYSTEM WIRING DIAGRAMS article for schematic and connector information.

PINPOINT TEST I: THE LEFT OR RIGHT EXTERIOR MIRROR BLIS™/CTA LED APPEARS DIM OR DOES NOT ILLUMINATE WITH NO DTC OR MESSAGE IN THE IPC MESSAGE CENTER PRESENT

Note. Use the correct probe adapter(s) when making measurements. Failure to use the correct probe adapter(s) may damage the connector.

Note. Failure to disconnect the battery when instructed will result in false resistance readings. Refer to BATTERY DISCONNECT .

1. I1 VERIFY THE CUSTOMER'S CONCERN Carry out the diagnostic system check. Start the engine. Observe the left and right exterior mirror BLIS™ / CTA LEDs and compare the illumination in each mirror. Is one LED noticeably dimmer than the other? Yes: GO to I2 . No: The concern may be due to customer perception or ambient lighting conditions. TEST the system for normal operation.
2. I2 VERIFY THE EXTERIOR MIRROR BLIS™/CTA LED OPERATION Ignition OFF. Apply the park brake. Ignition ON. Select REVERSE. Enter the following diagnostic mode on the scan tool: SOD-R and/or SOD-L DataLogger. NOTE: The SOD-R and SOD-L are separate modules and the active command PID needs to be commanded on in each individual module. Select the SOD-R or SOD-L PID (CTALERT) and active command the LED ON. Observe the left and/or right exterior mirror BLIS™ / CTA LED and message center. Does the LED blink brightly, audible tone and a message in the message center display "CTA ALERT"? Yes: The concern may be due to customer perception, ambient lighting conditions or system functionality. TEST the system for normal operation. No: GO to I3 .
3. I3 CHECK THE SOD-R OR SOD-L VOLTAGE SUPPLY CIRCUIT Ignition OFF. Disconnect: SOD-L C4230 or SOD-R C4229. Ignition ON. For a dim left LED, measure the voltage between the SOD-L C4230-5, circuit CBP35 (YE/GY), harness side and ground. For a dim right LED, measure the voltage between the SOD-R C4229-5, circuit CBP35 (YE/GY), harness side and ground. Is the voltage greater than 10 volts? Yes: GO to I4 . No: REPAIR the circuit in question. TEST the system for normal operation.
4. I4 CHECK THE SOD-R OR SOD-L GROUND CIRCUIT FOR AN OPEN Ignition OFF. Disconnect: Negative battery cable. For a dim left LED, measure the resistance between the SOD-L C4230-2, circuit GD171 (BK/GY), harness side and ground. For a dim right LED, measure the resistance between the SOD-R C4229-2, circuit GD171 (BK/GY), harness side and ground. Is the resistance less that 5 ohms? Yes: GO to I5 . No: REPAIR the circuit in question. TEST the system for normal operation.
5. I5 CHECK THE SUSPECTED EXTERIOR MIRROR BLIS™/CTA LED FOR ILLUMINATION Connect: Negative Battery Cable. Ignition OFF. For a dim left LED, connect a fused jumper wire between the SOD-L C4230-5, circuit CBP35 (YE/GY), harness side and the SOD-L C4230-6, circuit CRB04 (YE/GN), harness side. For a dim right LED, connect a fused jumper wire between the SOD-R C4229-5, circuit CBP35 (YE/GY), harness side and the SOD-R C4229-6, circuit CRB02 (BU./BAN), harness side. Ignition ON. Does the LED appear dim? Yes: GO to I6 . No: INSTALL a new SOD-R or SOD-L . REFER to «Removal and Installation»(ref-356018-S14146651352010013000000) . TEST the system for normal operation.
6. I6 CHECK THE SUSPECTED EXTERIOR MIRROR BLIS™/CTA LED CIRCUITS FOR AN OPEN Ignition OFF. Disconnect: Left Exterior Mirror BLIS™ / CTA LED Connector Or Right Exterior Mirror BLIS™ / CTA LED Connector. Ignition ON. For a dim left LED, measure the voltage between the left exterior mirror BLIS™ / CTA LED connector pin 1, harness side and the left exterior mirror BLIS™ / CTA LED connector pin 2, harness side. For a dim right LED, measure the voltage between the right exterior mirror BLIS™ / CTA LED connector pin 1, harness side and the right exterior mirror BLIS™ / CTA LED connector pin 2, harness side. Is the voltage greater than 10 volts? Yes: INSTALL a new exterior mirror for the LED in question. REFER to «REMOVAL AND INSTALLATION»(ref-356023-S16116166512010013000000) . No: GO to I7 .
7. I7 CHECK THE SUSPECTED EXTERIOR MIRROR BLIS™/CTA LED VOLTAGE SUPPLY CIRCUIT FOR AN OPEN

1. Ignition OFF.
2. For the left LED, measure the resistance between the SOD-L C4230-6, circuit CRB04 (YE/GN), harness side and left exterior mirror BLIS™ / CTA LED connector pin 1, harness side.
3. For the right LED, measure the resistance between the SOD-R C4229-6, circuit CRB02 (BU./BAN), harness side and the right exterior mirror BLIS™ / CTA LED connector pin 1, harness side.
4. Is the resistance less than 5 ohms?

1. Yes: For the left exterior mirror, REPAIR circuit GD126 (BK/WH) for an open. TEST the system for normal operation. For the right exterior mirror, REPAIR circuit GD139 (BK/YE) for an open. TEST the system for normal operation.
2. No: For the left exterior mirror, REPAIR circuit CRB04 (YE/GN) for an open. TEST the system for normal operation. For the right exterior mirror, REPAIR circuit CRB02 (BU./BAN) for an open. TEST the system for normal operation.
