Pinpoint Test AI: DTC B1359

Instrumentation and Warning Chimes

Pinpoint Test AI: DTC B1359

Refer to Wiring Diagrams Set 60, Instrument Cluster for schematic and connector information. Electrical Diagrams

- DTC B1359 (Ignition Run/Crank Circuit Failure)- sets in continuous memory if the Instrument Cluster (IC) detects voltage on the RUN input with no voltage on the ACC input for greater than 15 seconds. This DTC can be set if the engine has been cranked for longer than 15 seconds. The IC (Instrument Cluster) returns to normal function (gauges and the integrated circuit display operates) after the DTC sets.

Possible Causes

- Wiring, terminals or connectors

- IC (Instrument Cluster)

PINPOINT TEST AI : DTC B1359

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

AI1 RECHECK THE IC (Instrument Cluster) DTCs

- Ignition ON.

- Enter the following diagnostic mode on the scan tool: IC (Instrument Cluster) Self-Test.

- Clear the continuous DTCs. Repeat the IC (Instrument Cluster) self-test.

Is DTC B1359 still present?

Yes
GO to AI2.

No
The system is operating correctly at this time. The DTC may have been set due to a previous low battery voltage condition.

AI2 CHECK THE IC (Instrument Cluster) ACC CIRCUIT VOLTAGE

- Ignition OFF.

- Disconnect: IC (Instrument Cluster) C220A.

- Ignition In ACC.

- Measure the voltage between the IC (Instrument Cluster) C220A-14, circuit 75-GG14 (YE/BU), harness side and ground.





Is the voltage grater than 10 volts?

Yes
CLEAR the DTCs. SWITCH the ignition to the RUN position for greater than 15 seconds and REPEAT the self-test. If DTC B1359 returns, INSTALL a new IC (Instrument Cluster). REFER to Instrument Cluster (IC) .

No
CHECK CJB (Central Junction Box) fuse 137. If OK, GO to AI3. If not OK, REFER to the Wiring Diagrams to repair the circuit short to ground. Electrical Diagrams

AI3 CHECK THE IC (Instrument Cluster) ACC CIRCUIT FOR AN OPEN

- Disconnect: CJB (Central Junction Box) Fuse 137.

- Measure the resistance between the IC (Instrument Cluster) C220A-14, circuit 75-GG14 (YE/BU), harness side and CJB (Central Junction Box) fuse 137 pin socket, circuit 75-GG14 (YE/BU).





Is the resistance below 5 ohms?

Yes
GO to AI4.

No
REPAIR circuit 75-GG14 (YE/BU) for an open. CLEAR the DTCs. REPEAT the self-test.

AI4 CHECK FOR CORRECT IC (Instrument Cluster) OPERATION

- Disconnect the IC (Instrument Cluster) connector.

- Check for:
- corrosion

- damaged pins

- pushed-out pins


- Connect the IC (Instrument Cluster) connector 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 IC (Instrument Cluster). REFER to Instrument Cluster (IC) . TEST the system for normal operation.

No
The system is operating correctly at this time. The concern may have been caused by a loose or corroded connector. CLEAR the DTCs. REPEAT the self-test.
