Pinpoint Test J: DTC B1360 - Ignition Acc/Run Circuit Open

J1 CHECK CENTRAL JUNCTION BOX (CJB) FUSE 15 (5A) OR 30 (5A) FOR VOLTAGE
- Key in ACCESSORY position.
- Disconnect: CJB Fuse 15 (5A).
- Disconnect: CJB Fuse 30 (5A).
- Measure the following voltages:
  - between the CJB fuse cavity 15, input side and ground.
  - between the CJB fuse cavity 30, input side and ground.
- Are the voltages greater than 10 volts?
- Yes : GO to J2.
- No : GO to J3.
J2 CHECK CIRCUITS 295 (LB/PK) OR 489 (PK/BK) FOR AN OPEN
- Key in OFF position.
- Disconnect: Instrument Cluster C220a.
- Disconnect: Instrument Cluster C220b.
- Measure the following resistances:
  - between the instrument cluster C220a-18, circuit 295 (LB/PK), harness side and the CJB fuse cavity 15 output side, circuit 295 (LB/PK).
  - between the instrument cluster C220b-7, circuit 489 (PK/BK), harness side and the CJB fuse cavity 30 output side, circuit 489 (PK/BK).
- Are the resistances less than 5 ohms?
- Yes : GO to J6.
- No : REPAIR circuit 295 (LB/PK) or circuit 489 (PK/BK). TEST the system for normal operation.
J3 CHECK CIRCUITS 687 (GY/YE) OR 16 (RD/LG) FOR AN OPEN
- Disconnect: Ignition Switch C250.
- Measure the following resistances:
  - between the ignition switch 250-6, circuit 687 (GY/YE), harness side and the CJB fuse cavity 15 input side, circuit 687 (GY/YE).
  - between the ignition switch C250-1, circuit 16 (RD/LG), harness side and the CJB fuse cavity 30 input side, circuit 16 (RD/LG).
- Are the resistances less than 5 ohms?
- Yes : GO to J4.
- No : REPAIR circuit 687 (GY/YE) or circuit 16 (RD/LG). TEST the system for normal operation.
J4 CHECK THE IGNITION SWITCH
- CARRY OUT the Ignition Switch Component Test. Refer to COMPONENT TESTING article for component testing.
- Is the ignition switch OK?
- Yes : GO to J5.
- No : INSTALL a new ignition switch. REFER to STEERING COLUMN SWITCHES . TEST the system for normal operation.
J5 CHECK THE CJB
- Key in OFF position.
- Measure the resistance between the following CJB fuses input side and output side cavities:
  - between the CJB fuse 15 input side and output side cavities.
  - between the CJB fuse 30 input side and output side cavities.
- Are the resistances less than 5 ohms?
- Yes : GO to J6.
- No : INSTALL a new CJB. TEST the system for normal operation.
J6 CHECK THE IGNITION SWITCH PIDS
- Connect the diagnostic tool.
- Monitor the instrument cluster ignition ACC and RUN PIDs while cycling the ignition from ACC to RUN.
- Do the PIDs indicate the ignition switch position correctly?
- Yes : GO to J7.
- No : INSTALL a new instrument cluster. refer to INFORMATION GAUGES AND WARNING DEVICES article . REPEAT the self-test.
J7 CHECK FOR CORRECT INSTRUMENT CLUSTER OPERATION
- Key in OFF position.
- Disconnect all instrument cluster connectors.
- Check for:
  - corrosion
  - pushed-out pins
- Connect all instrument cluster connectors and make sure they are seated correctly.
- Operate the system and verify the concern is still present.
- Is the concern still present?
- Yes : INSTALL a new instrument cluster. refer to INFORMATION GAUGES AND WARNING DEVICES article . REPEAT the self-test.
- No : The system is operating correctly at this time. Concern may have been caused by a loose or corroded connector. TEST the system for normal operation.
