b W ait 15 seconds for the battery to recover.
8 If possible, set the selector to 50% of rapid discharge current (or three times the 20 hour discharge rate).
9 Apply the load test for 10 seconds and record the battery voltage. If one cell is faulty it will gas excessively or overheat. This indicates a faulty battery.
10 Recharge the battery if the voltage is at or below the minimum voltage specified by the HRD manufacturer (or 9.6 V).
11 Replace the battery if the voltage is below the minimum voltage specified by the HRD manufacturer (or below 9.6 V after the battery is charged and the test is repeated). Refer to 4.1 Battery.
12 Connect the battery positive terminal.
13 Connect the battery negative terminal.
Alternate Load Test
If HRD test equipment is not available, test the battery as follows:
1 Read and obey the safety precautions for working with batteries, refer to 2 Safety Precautions.
2 Ensure the state of the battery is at least 65% charged. Refer to 3.3 Hydrometer Test.
3 Connect a voltmeter (1) between the battery terminals.
4 Turn the headlights on to high-beam for 10 seconds to remove any surface charge from the battery.
5 Remove fuses EB11 and EB12 from the engine compartment fuse and relay housing. This prevents
vehicle ignition and fuel injection while cranking the
engine.
6 Crank the engine and read the voltmeter. At temperatures above 5°C, the voltage of a fully charged
battery should not fall below 9.6 V.
NOTE
• If the battery and engine temperatures are
below 5 °C, the voltage may fall to 9 V.
• Try to avoid activating the starter motor
continuously for more than 30 seconds. If
activating the starter motor for 30 seconds,
allow the starter motor to cool for 3 minutes.
7 Replace the battery if a cell gasses excessively or overheats or if the voltage falls away quickly.
Figure 6D1-3 – 6
3.5 Battery Current Draw Test
The following test determines if excess current is being drawn from the battery whilst the vehicle has all accessories
turned off. Excess current draw will cause the battery to go flat if the vehicle is not started for an extended period.
Test Preparation
1 Read and obey the safety precautions for working with batteries, refer to 2 Safety Precautions.
2 If the battery is flat, temporarily install a good battery for the duration of the test.
3 Ensure the vehicle starts and the accessories operate normally.
4 Ensure the theft deterrent system operates normally. Refer to 11A Immobiliser.
5 Open all the side windows for access purposes.
6 Switch the ignition off.
7 Check that all interior illumination is off, including any compartment lighting.
8 Close all doors.

Step Action Yes No
2 1 Connect Tech 2 to the DLC.
2 Turn on the ignition, with the engine off.
NOTE
Before clearing the DTC, use the Tech 2 Freeze
Frame/Failure Record to record the transmission
parameters at the time the DTC set. Using Tech 2 to clear
the DTC(s) erases the Freeze Frame/Failure Record
records from the TCM.
3 On Tech 2 select: Transmission / Automatic Transmission / Diagnostic
Trouble Codes / Freeze Frame.
4 Select the relevant DTC and note the parameters at the time of the DTC setting.
5 On Tech 2 select:
Diagnostic Trouble Codes / Clear Engine & Transmission
DTCs.
6 Follow the instructions on Tech 2 and clear the DTCs.
7 Using a multimeter set to measure voltage, probe across the battery terminals.
Does the multimeter display greater than 11 V? Go to Step 3 Check the
serviceability of the battery, refer to
8A Electrical-Body and Chassis
3 1 Start the engine.
2 Allow the engine to warm up to normal operating temperature.
Is the alternator fail warning indicator illuminated? Refer to
6D1-1 Charging system – V6 Go to Step 4
4 1 Turn on the high beam headlamps.
2 Turn the HVAC fan control to the highest speed setting.
3 Turn on the rear window demister.
4 Increase the engine speed to 1,500 r.p.m.
5 Using a multimeter set to measure voltage, probe across the battery terminals.
Does the multimeter display 12.5 – 14.5 V? Go to Step 5 Refer to
6D1-1 Charging system – V6
5 1 Increase the engine speed to 1,500 r.p.m.
2 On Tech 2 select: Data Display / Transmission Data
Does Tech 2 display the Ignition Voltage parameter within 12.5 –
14.5 V? Check for an
intermittent fault in the circuit, refer to
8A Electrical-Body
and Chassis Go to Step 6
6
Check the fuses EB-4 and C-8 for serviceability.
Are the fuses serviceable?
Go to Step 7 Replace the
affected fuse(s). If the fuse(s) blow
again, check for a short to ground in the fuses circuit
Go to Step 13
7 1 Turn off the ignition.
2 Disconnect the TCM connector C-96.
3 Using a multimeter set to measure voltage, probe between connector C-96 pin 32 and a known ground.
Does the multimeter display battery voltage? Go to Step 8 Check measured
circuits for an open,
high resistance or short to ground
Repair or replace
the affected circuit
