Ranger 2WD V6-3.0L (2008)
Body Control Systems: Pinpoint Tests
PINPOINT TEST A: DTC B106E - SOLID STATE DRIVER DISABLED DUE TO SHORT CIRCUIT
Normal Operation
The SJB controls the output of the daytime running lamps (DRL), fog lamps, one-touch down driver power window, accessory delay relay, windshield
wiper park/run, windshield wiper speed, and windshield washer. When a repetitive fault causing a circuit overload is detected on any of the output
circuits, the SJB disables the circuit by removing voltage, or ground, to the affected circuit. The circuit remains disabled until the fault is corrected and
an on-demand self-test is run. After the on-demand self-test has been run, any DTCs related to the fault will be cleared.
-
DTC B106E (Solid State Driver Disabled Due to Short Circuit) - sets when the SJB has temporarily disabled a circuit due to a repetitive fault
causing a circuit overload. A corresponding DTC for the circuit in question will also set as follows:
-
DTC B106F (Module Disabled Due to External Fault) - sets when one or more output functions are permanently disabled due to a repetitive circuit
overload fault. DTC B106F will be set with DTC B106E. When DTC B106F is present, the SJB must be replaced after the fault condition has
been corrected.
-
DTC B1304 (Accessory Delay Relay Coil Circuit Short to Battery) - Accessory delay relay circuit short to battery voltage
-
DTC B2512 (Front Fog Lamp Relay Ckt Short to Battery) - Fog lamp relay circuit short to battery voltage
-
DTC B2973 (Daytime Running Lamp Output Shorted to Ground) - DRL output short to ground
This pinpoint test is intended to diagnose the following:
-
Output circuit short to ground or voltage
-
SJB
