Body Control Module: Vehicle Damage Warnings
Before disconnecting any control module, make sure the ignition is off. Failure to do so could damage the module.
When testing voltage or continuity at any control module, use the terminal side (not the wire end) of the connector. Do not probe a wire through the
insulation; this will damage it and eventually cause it to fail because of corrosion.
Be careful when performing electrical tests so as to prevent accidental shorting of terminals. Such mistakes can damage fuses or components. Also, a
second code could be set, making diagnosis of the original problem more difficult.
VEHICLE PREPARATION FOR TESTING
Make sure the vehicle being tested has a fully charged battery. If it does not, false diagnostic codes or error messages may occur.
SERVICING SUB-ASSEMBLIES
Some components of the powertrain system are intended to be serviced as assembly only. Attempting to remove or repair certain system
sub-components may result in personal injury and/or improper system operation. Only those components with approved repair and installation
procedures should be serviced.
DRBIII SAFETY INFORMATION
WARNING: Exceeding the limits of the DRB multimeter is dangerous. It can expose you to serious or possibly fatal injury. Carefully read and
understand the cautions and the specification limits.
-
Follow the vehicle manufacturer's service specifications at all times.
-
Do not use the DRB if it has been damaged.
-
Do not use the test leads if the insulation is damaged or if metal is exposed.
-
To avoid electrical shock, do not touch the test leads, tips, or the circuit being tested.
-
Choose the proper range and function for the measurement. Do hot try voltage or current measurements that may exceed the rated capacity.
-
Do not exceed the limits shown in the table below:
FUNCTION
INPUT LIMIT
Volts
0 - 500 peak volts AC
0 - 500 volts DC

-
Voltage between any terminal and ground must not exceed 500v DC or 500v peak AC.
-
Use caution when measuring voltage above 25v DC or 25v AC.
-
A 10A fuse or circuit breaker must protect the circuit being tested.
-
Use the low current shunt to measure circuits up to 10A. Use the high current clamp to measure circuits exceeding 10A.
-
When testing for the presence of voltage or current, make sure the meter is functioning correctly. Take a reading of a known voltage or current
before accepting a zero reading.
-
When measuring current, connect the meter in series with the load.
-
Disconnect the live test lead before disconnecting the common test lead.
-
When using the meter function, keep the DRB away from spark plug or coil wires to avoid measuring error form outside interference.
