Normal Operation

NOTE:

The smart junction box (SJB) is also known as the generic electronic module (GEM).

DTC B1363 sets when the instrument cluster senses voltage applied to the run/start circuit (Y/O) for more than 15 seconds.

This pinpoint test is intended to diagnose the following:

Instrument cluster

IGNITION START CIRCUIT FAULT PINPOINT TEST 23

PINPOINT TEST 23		DTC B1363 - IGNITION START CIRCUIT FAULT
STEP	INSPECTION		ACTION
1	RETRIEVE THE RECORDED DTCs FROM BOTH THE CONTINUOUS AND ON-DEMAND INSTRUMENT CLUSTER SELF-TESTS Retrieve the recorded DTCs from the instrument cluster continuous and on-demand self-tests. Is DTC B1363 retrieved?	Yes	CLEAR the DTCs. REPEAT the self-tests. If DTC B1363 is retrieved again, go to next step.
1		No	The system is operating normally at this time. The concern may have been caused by the ignition switch left too long in the start position.
2	MONITOR SJB/GEM IGNITION SWITCH POSITION PIDs Key in ON position. Enter the following diagnostic mode on the scan tool: SJB/GEM DataLogger Select and monitor the SJB/GEM ignition switch (IGN_SW) PID while moving the ignition switch from run to start. Do the PID values match the ignition switch position?	Yes	Go to next step.
2		No	See STEERING COLUMN SWITCHES , to diagnose the ignition switch inputs to the SJB/GEM.
3	CHECK FOR CORRECT INSTRUMENT CLUSTER OPERATION Disconnect all the instrument cluster connectors. Check for: corrosion damaged pins pushed-out pins Connect all the instrument cluster connectors and make sure they seat correctly. Operate the system and verify the concern is still present. Is the concern still present?	Yes	INSTALL a new instrument cluster. See INSTRUMENT CLUSTER . TEST the system for normal operation.
3		No	The system is operating correctly at this time. The concern may have been caused by a loose or corroded connector.
