4. The dash voltmeter should now indicate traction battery pack voltage.
5. Check main fusible link F9 (under the rear seat in rubber boot on sedan, under dump bed by
contactors in middle on PK).
6. Check voltage on each battery in the traction battery stack. Each battery should not differ by
more than – 0.09 volts from the battery with the highest voltage. Charge any low battery
with a 12V battery charger to try to bring up that battery voltage by eliminating plate
sulfation. Also check battery wires for loose or corroded connections.
7. Check all fuses. In the sedan specifically F1 and F6.
8. DC/DC converter bad.
Won't drive forward:
1. Set direction switch K23 to "F".
2. Unplug vehicle from wall socket. (Charge interlock will prevent the vehicle from going)
3. Make sure emergency and foot brake are off.
4. Check all fuses especially F5 in sedan.
5. Diode D6 bad.
6. If forward contactor J3 does not close, the charger disable relay JDac, JD5, control contactor
J4 or fuse F5 (in sedan) could be bad.
7. If motor controller A21 green power light does not come on, diode D5 could be bad or
controller power wire T9 connection could be loose or off.
8. If main contactor J1 does not activate, relay JD7, diodes D3 or D4 and foot and emergency
brake switches could be bad in addition to above.
9. The 5K accelerator A25 could be bad or the connectors could be off or loose on controller
A21.
10.Main contactor J1, forward contactor J3, reverse contactor J2, controller A21 or motor A22
could be bad.
11.The motor controller should have a solid green light if all is OK, see motor controller below
if there is a problem.
Won't drive in Reverse:
1. Set direction switch to "R".
2. Press and release the red reverse button K22.
3. Same description as above but substitute diode D6.
4. The backup lights should come on and the reverse beeper should start sounding.
5. If reverse button K22 must be held in, relay JD2 could be bad.
6. If the backup lights and beeper don't work, relay JD1, the lights or beeper could be bad.
Vehicle won't charge:
1. No power at wall socket, check circuit breaker at box.
2. Charging cord not plugged in, or cord is faulty.
3. The charging port male connector under the “gas cap” is faulty or a wire is loose.
4. On some vehicles there is a GFI breaker. Make sure this has not tripped. This is located
above the charger on the rear firewall of the sedan (if present) and by the charging port under
the “gas cap” lid on the PK.
5. Red main disconnect K21 is off. Pull OUT to turn on.
6. Check fusible link F9 (under the rear seat in rubber boot).
7. Break in main voltage pack. Check wiring and main battery connections. Clean repair, any
corroded or broken connections.
