ROUTINE 8: VEHICLE DOES NOT CHARGE (LEAD ACID VEHICLES)

TEST STEP

ACTION TO TAKE

8-1 CHECK STATUS OF BATTERY CONTROL MODULE (BCM)

OPERATING STATE

•

Verify the ignition key is in the OFF position and the gear selector is in

the P (Park) position.

Connect the vehicle to a power control station (PCS) and press the

START button to begin charging.

NOTE: Wait approximately five minutes to allow the BCM OP PID to

be set.

•

With key OFF and vehicle on-charge, monitor BCM PID BCM OP.

Check for the following numbers:

— 48 (shutdown-low battery module voltage)

Yes =

If 48, GO to 8-2.

— 83 (no charge-battery overtemperature)

If 83, GO to 8-5.

— 84 (no charge-battery undertemperature)

If 84, GO to 8-8.

— 87 (no charge-battery full)

If 87, the traction battery is

at full state of charge

(SOC). System OK.

— 96 (no charge-EPO detected)

If 96, GO to 8-12.

— 99 (no charge-line capacity out of range)

If 99, GO to 8-15.

— 101 (no charge-no AC to charger)

If 101, GO to 8-24.

•

Does the BCM OP PID indicate 48, 83, 84, 87, 96, 99, or 101?

No =

GO to 8-29.

8-2 CHARGE TRACTION BATTERY TO FULL STATE OF CHARGE

(SOC)

•

Disconnect and reconnect the 12-volt auxiliary battery negative cable.

Yes =

GO to 8-3.

•

Charge the traction battery to full SOC.

No =

System OK.

•

With key ON, monitor BCM PID BCM OP.

•

Does the BCM OP PID still indicate 48 (shutdown-low battery

module voltage)?
