3 Diagnosis
3.1 Diagnostic Procedures
Introduction
This test is used to aid in diagnosing faults with the vehicle where the battery seems to be at fault.
W ith the increased use of electronic sensors and computer control, the battery is much more than just a component used
to start a car. Low battery voltage can:
• affect the operation of the vehicle control modules and cause driveability problems, and
• cause the control modules to set diagnostic trouble codes (DTCs).
For example if a control module senses low battery voltage, it may increase fuel injector timing to increase engine rpm to
increase the generator output.
Therefore consider the state of charge of the battery any time a customer complains of a driveability related problem.
Test Description
The following numbers refer to the step numbers in the diagnostic table:
1 Checks the operator understands the safety precautions for working with batteries.
2 Checks if the vehicle is fitted with a battery of the correct specification.
3 Checks if the battery appears serviceable by performing the battery inspection procedure.
4 Checks if the battery loses charge over an extended period. If so the likely problem is excess current draw while the vehicles ignition is in the off position.
5 Checks the state of charge of the battery.
6 Checks if the battery is capable of delivering the required load by performing the load test procedure.
Diagnostic Table Notes
1 For all wiring harness fault diagnosis, refer to 8A Electrical Body & Chassis.
2 For wiring harness repairs, refer to 8A Electrical Body & Chassis.
3 Refer to 6D1 – 3 Battery – V6.
Diagnostic Table
Step Action Yes No
1
Have you read and understood the safety precautions for working with
batteries? Go to Step 2 Refer to 2
Safety Precautions
2 Check the battery fitted is the correct specification recommended for
the vehicle? Refer to 5 Specifications.
Is the battery the correct specification? Go to Step 3 Replace the battery
with the correct
specification
3 Perform the battery inspection, refer to 3.2 Battery Inspection.
Does the battery appear serviceable? Go to Step 4 Replace the battery,
refer to 4.1

4 Does the customer complain the battery loses charge if the engine is
not started for an extended period? Preform the battery
current draw test, refer to 3.5
