No communication with the smart junction box (SJB)	Fuse SJB Wiring, terminals or connectors	REFER to MODULE COMMUNICATIONS NETWORK article.

SYMPTOM CHART

Pinpoint Test A: DTC B106E - Solid State Driver Disabled Due To Short Circuit

Normal Operation

The smart junction box (SJB) controls the output of several vehicle systems by means of solid state drivers. When an overload occurs on any of these drivers, a DTC will be set. The module also tracks the number of repetitive faults on each of these circuits. The module compares this number of overloads to 3 progressive thresholds established for each circuit. If the 3 thresholds have not been exceeded, then the DTC for the affected circuit can be cleared by eliminating the fault, then clearing the DTCs and running a self-test. At the point that each of the first 2 thresholds are exceeded, the DTC B106E will be set along with the DTC relating to the affected circuit. Once the final (third) threshold is exceeded, the affected output is permanently disabled, and the DTC B106F will be set along with the DTC B1342, at which time the SJB must be replaced.

DTC B106E (Solid State Driver Disabled Due to Short Circuit) - sets when the SJB has disabled a circuit due to a repetitive fault causing a circuit overload. A corresponding DTC for the circuit in question will also set.
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, a new SJB must be installed after the fault condition has been corrected.

This pinpoint test is intended to diagnose the following

Output circuit short to ground or voltage
SJB

PINPOINT TEST A: DTC B106E - SOLID STATE DRIVER DISABLED DUE TO SHORT CIRCUIT

CAUTION

If DTC B106F is present and a new SJB is to be installed, the fault condition must be corrected first. Failure to correct the fault condition first may cause damage to the new SJB, resulting in a repeat repair.

Note. If DTC B106F is present, DTC B1342 may also be present. At this time, ignore these DTCs and follow the necessary diagnostics to resolve the DTC B106E and any other DTCs that are present. DTC B106E will be present only when there is another DTC due to a software issue or a circuitry issue that must be resolved before another self-test is run. Each time a self-test is run, one of the 3 thresholds is used up. Once the 3 thresholds are used up, DTCs B106F and B1342 will be present and the SJB must be replaced. All other DTCs MUST be resolved first, or else the new SJB will begin to have its 3 thresholds used up with each self-test that is run.

A1 REVIEW THE DTCs Review the DTCs from the SJB self-test. Are only DTCs B106E and B106F present? YES : INSTALL a new SJB. REFER to «Smart Junction Box (SJB)»(ref-292540-S29685201802008080400000) . TEST the system for normal operation. NO : CORRECT any DTCs present other than DTCs B106E and B106F. REFER to «Diagnostic Trouble Code (DTC) Chart»(ref-292540-S28006878492008080400000) . After the repair, go to A2 .
A2 CARRY OUT THE SJB SELF-TEST Carry out the SJB self-test. Is only DTC B106F present (DTC B1342 may also be present)? YES : INSTALL a new SJB. REFER to «Smart Junction Box (SJB)»(ref-292540-S29685201802008080400000) . TEST the system for normal operation. NO : The system is operating correctly at this time. The concern was caused by a fault in one of the output circuits.

Pinpoint Test B: DTCs B2048, B2049, B2050, B2051, B2949, B2A2B, B2A2C, B2A37, B2A38 - Possible Smart Junction Box (SJB) Internal Errors

Normal Operation

If the smart junction box (SJB) is not configured correctly, these DTCs may appear in error. The SJB will need to be configured correctly, possibly using the As-Built data, in order to correct this issue and clear the DTCs. If not, then the following pinpoint test will need to be carried out to determine if the SJB is at fault.

Note. The pins mentioned in the chart below are not populated.

Note. These DTCs are not applicable to a correctly configured vehicle. If they are present, either the vehicle has been incorrectly configured, or the SJB may be damaged.
