 The entire bulletin has been updated.
Any previous printed versions of this bulletin should be discarded.

Introduction

This bulletin includes basic procedures for performing a rescue charge on Ni-MH high voltage
(HV) batteries. This bulletin should be used in conjunction with the applicable model and model
year Repair Manual while performing the rescue charge. The GRX-5100 should be used
wherever the Repair Manual references the Toyota Hybrid System (THS) charger.

Rescue Charge Ni-MH

1. Preliminary vehicle inspection.
A. Inspect auxiliary battery voltage.
B. Measure the voltage between the terminals of the auxiliary battery.
NOTE
 Standard voltage is approximately 11V or more.
 If the voltage is 11V or less, either charge the auxiliary battery or replace it with an auxiliary
battery that is already charged.

2. Inspect the HV battery.
CAUTION
 ALWAYS wear the appropriate Personal Protective Equipment (PPE) provided in the
HEV Workstation when working with high voltage. (Insulated gloves, insulated
apron, and arc protective helmet with face shield).
 ALWAYS use insulated tools when working with high voltage.
 ALWAYS use the cones, barriers and high voltage car toppers provided in the HEV
Workstation to create a perimeter around the vehicle and work area.
HINT
 Removing the service plug grip interrupts the high voltage circuit.
 High voltage wiring and connectors are orange.

A. Check the charge level of the HV battery.
B. Check if the HV battery warning message is shown in the vehicle’s
multi-information display.
C. Confirm if the engine starts.
Does the engine start?


YES — Go to step 6.



NO — Continue to step 3.

3. Connect the GRX-5100 for rescue charge.
HINT
 ALWAYS use the Techstream to troubleshoot the hybrid system before attempting
HV battery charge.
 Charging time while using the GRX-5100 is 10 minutes per charge cycle when the battery
temperature is above 77°F (25°C); 10 minutes may be sufficient, if the battery temperature is
below 32°F (0°C), then three 10-minute charge cycles may be required for putting the engine in
a condition where it can be started (the system can enter the READY ON state). The GRX-5100
will automatically stop 10 minutes AFTER charging starts.

A. Disconnect the 12V auxiliary battery.
B. Use the table below to select the high voltage and low voltage cables for a specific
model. Some vehicles may also require a high voltage accessory.
