- Retrieve the CMDTCs (Continuous Memory Diagnostic Trouble Codes) from all modules.

Is DTC B11E8:17, B1317, B1676, P0563 (PCM) or U3003:17 set in more than one module?

Yes
REFER to Charging System to diagnose an overcharging condition.

No
GO to B2.

B2 CHECK THE BATTERY VOLTAGE

- Turn off all interior/exterior lights and accessories.

- Start and run the engine at approximately 2,000 rpm for 3 minutes while monitoring the battery voltage.

Does the battery voltage rise to 15.5 volts or higher?

Yes
REFER to Charging System to diagnose an overcharging condition.

No
GO to B3.

B3 RECHECK FOR DTC B11E8:17

- Turn the engine off.

- Ignition ON.

- Enter the following diagnostic mode on the scan tool: ABS Module Self-Test.

- Clear the CMDTCs (Continuous Memory Diagnostic Trouble Codes).

- Carry out the ABS module self-test.

Is DTC B11E8:17 present?
