Pinpoint Test K: DTCs B1317 and B1318

Anti-Lock Control

Pinpoint Test K: DTCs B1317 and B1318

Normal Operation

The voltage range required to operate the Steering Angle Sensor Module (SASM) is 8-16 volts.

Fused ignition voltage is supplied to the SASM (Steering Angle Sensor Module) from Smart Junction Box (SJB) fuse 35 (10A) along circuit CBP35 (YE/GY), ground is provided along circuit GD114 (BK/BU). The module communicates with other modules along the High Speed Controller Area Network (HS-CAN) bus, circuits VDB05 (WH) and VDB04 (WH/BU).

- DTC B1317 (Battery Pack Voltage Out of Range)- If the battery voltage is higher than 16 volts for more than 100 ms, DTC B1317 will be set.

- DTC B1318 (Battery Pack Voltage Out of Range)- If the battery voltage is lower than 8 volts for more than 100 ms, DTC B1318 will be set.

This pinpoint test is intended to diagnose the following:

- Fuse(s)

- Wiring, terminals or connectors

- SASM (Steering Angle Sensor Module)

- Charging system

PINPOINT TEST K : DTCs B1317 AND B1318

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

K1 RETRIEVE ALL CMDTCs (Continuous Memory Diagnostic Trouble Codes) IN ALL MODULES

- Ignition ON.

- Enter the following diagnostic mode on the scan tool: Self Test- ALL CMDTCs (Continuous Memory Diagnostic Trouble Codes).

Is DTC B1317, B1318 or B1676 retrieved from more than one module AND P0563, P0620, P0626 or P065B retrieved from the PCM?

Yes
REFER to Charging System to diagnose the charging system. CLEAR the DTCs. REPEAT the self-test.

No
GO to K2.

K2 TEST BATTERY CONDITION

- Ignition OFF.

- Carry out the Battery Condition Test. Pinpoint Tests

Did the battery pass the condition test?

Yes
If the battery passed the condition test, but required a recharge, REFER to Charging System to diagnose the charging system. CLEAR all Continuous Memory Diagnostic Trouble Codes (CMDTCs). TEST the system for normal operation.

If the battery passed the condition test and did not require a recharge, GO to K3.

No
INSTALL a new battery. CLEAR the DTCs. REPEAT the self-test.

K3 CHECK CHARGING SYSTEM VOLTAGE

NOTE: Do not allow the engine speed to increase above 2,000 rpm while performing this step or the generator may self excite and result in default charging system output voltage. If engine speed goes above 2,000 rpm, shut the vehicle OFF and restart the engine before performing this step.

- Start the engine.

- Measure the voltage of the battery:
- For DTC B1317, turn off all accessories and run the engine at 1,500 rpm for a minimum of 2 minutes while measuring battery voltage.

- For DTC B1317, turn on headlights and HVAC fan on high and run engine at 1,500 rpm for a minimum of 2 minutes while measuring battery voltage.






Are the voltages between 13 and 15.2 volts?

Yes
For DTC B1318, GO to K4.

For DTC B1317, INSTALL a new SASM (Steering Angle Sensor Module). REFER to SASM (Steering Angle Sensor Module). CLEAR the DTCs. REPEAT the self-test.

No
REFER to Charging System to diagnose the charging system. CLEAR the DTCs. REPEAT the self-test.

K4 CHECK THE VOLTAGE TO THE SASM (Steering Angle Sensor Module)

- Ignition OFF.

- Disconnect: SASM (Steering Angle Sensor Module) C2412.

- Ignition ON.

- Measure the voltage between SASM (Steering Angle Sensor Module) C2412-1, CBP35 (YE/GY), harness side, and ground.





Is the voltage greater than 10 volts?

Yes
GO to K5.

No
VERIFY SJB (Smart Junction Box) fuse 35 (10A) is OK. If OK, REPAIR the affected circuit(s).

If not OK, Refer to the Wiring Diagrams to identify possible causes of the circuit short. CLEAR the DTCs. REPEAT the self-test. Electrical Diagrams

K5 CHECK THE SASM (Steering Angle Sensor Module) GROUND CIRCUIT FOR AN OPEN

- Ignition OFF.

- Disconnect: Negative Battery Cable

- Measure the resistance between SASM (Steering Angle Sensor Module) C2412-4, GD114 (BK/BU), harness side, and ground.





Is the resistance less than 5 ohms?

Yes
GO to K6.

No
REPAIR circuit GD114 (BK/BU). CLEAR the DTCs. REPEAT the self-test.

K6 CHECK FOR CORRECT SASM (Steering Angle Sensor Module) OPERATION

- Check SASM (Steering Angle Sensor Module) C2412 for:
- corrosion.

- pushed-out pins.

- spread terminals.


- Connect: C2412.

- Operate the system and verify the concern is still present.

Is the concern still present?

Yes
INSTALL a new SASM (Steering Angle Sensor Module). REFER to Steering Angle Sensor Module (SASM) . CLEAR the DTCs. REPEAT the self-test.

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.
