Pinpoint Test
PINPOINT TEST A : MAIN ENGINE COMPARTMENT BATTERY CONDITION TEST
Normal Operation and Fault Conditions
Battery condition is determined by measuring
battery terminal voltage after a specific discharge current is applied
for a specified time period.
Possible Sources
- Main Battery
- Wiring, terminals or connectors
Visual Inspection and Pre-checks
- Inspect wiring, terminals and connectors.
- Inspect the main engine compartment battery.
- Inspect the main engine compartment battery mounting.
- Inspect high current BJB connections.
|
A1 TEST THE MAIN ENGINE COMPARTMENT BATTERY CONDITION |
NOTE:
Failure to fully charge the battery before retesting may cause false readings.
-
Using the Diagnostic Battery Charger and the battery
cables removed from the battery, verify the battery condition.
Is the battery OK?
Yes |
RETURN the battery to service.
|
No |
If the analyzer reads REPLACE BATTERY or REPLACE-BAD CELL, INSTALL a new battery. REFER to: Battery (414-01 Battery, Mounting and Cables, Diagnosis and Testing).
|
|
PINPOINT TEST B : AUXILIARY BATTERY CONDITION TEST
Normal Operation and Fault Conditions
Battery condition is determined by measuring
battery terminal voltage after a specific discharge current is applied
for a specified time period.
Possible Sources
- Auxiliary Battery
- Wiring, terminals or connectors
Visual Inspection and Pre-checks
- Inspect wiring, terminals and connectors.
- Inspect the auxiliary battery.
- Inspect the auxiliary battery mounting.
- Inspect high current BJB connections.
|
B1 TEST THE AUXILIARY BATTERY CONDITION |
NOTE:
Failure to fully charge the battery before retesting may cause false readings.
-
Disconnect and Remove the auxiliary battery and allow the battery to reach room temperature.
REFER to: Battery Disconnect and Connect (414-01 Battery, Mounting and Cables, General Procedures).
-
Charge the auxiliary battery for 1 hour at 2 amps on AGM setting.
-
After the battery is charged, Remove the auxiliary
battery's surface charge by connecting an incandescent (non-LED) test light for 5 minutes.
-
Allow the auxiliary battery to rest for 15 minutes.
-
Measure the auxiliary battery voltage.
Is the auxiliary battery voltage greater than 12 volts?
Yes |
RETURN the battery to service.
|
No |
INSTALL a new auxiliary battery. REFER to: Battery (414-01 Battery, Mounting and Cables, Diagnosis and Testing).
|
|
PINPOINT TEST C : B11D9:09
Normal Operation and Fault Conditions
The BCM monitors both the main battery and auxiliary battery. The main battery has a BMS and the auxiliary battery has a battery current sensor. The BMS for the main battery communicates on a dedicated LIN to the BCM. The battery current sensor for the auxiliary battery uses a PWM circuit which is wired to the BCM.
DTC Fault Trigger Conditions
DTC |
Description |
Fault Trigger Condition |
BCM B11D9:09 |
Vehicle Battery: Component Failures |
Sets in the BCM when the BMS senses a failed battery due to one of the following conditions.
-
Failure of the 12 volt main engine compartment battery
-
Disconnected 12 volt main engine compartment battery
-
Failure of the 12 volt auxiliary battery set after 10 engine cranks
-
Open auxiliary battery fuse (in the high current BJB)
-
Open auxiliary battery fuse (attached to the auxiliary battery post)
-
Disconnected 12 volt auxiliary battery, set after 10 engine cranks
|
Possible Sources
- Auxiliary battery
- Auxiliary battery fuses
- Main engine compartment battery
- Main engine compartment battery and auxiliary battery connections
Visual Inspection and Pre-checks
- Verify the auxiliary battery fuses
|
C1 INSPECT ALL BATTERY CONNECTIONS |
-
Inspect the 12 volt main engine compartment battery connections.
-
Inspect the 12 volt auxiliary battery connections.
Are all battery cable connections securely fasten to the main and auxiliary battery?
No |
Secure the loose battery cable(s) connections to the battery.
|
|
C2 CHECK THE AUXILIARY BATTERY FUSE |
-
Verify that the auxiliary battery fuses are ok.
-
auxiliary battery fuse located in the high current BJB
-
auxiliary battery fuse located on the auxiliary battery positive post
Are the auxiliary battery fuses ok?
No |
Verify that the battery cable is not shorted, If OK,
Install a new auxiliary battery fuse(s). If shorted, REPAIR or REPLACE
the auxiliary battery cable as needed.
|
|
C3 VERIFY THE BATTERIES CONDITION |
-
Verify that the main battery and auxiliary battery condition. For the main battery GO to Pinpoint Test A For the auxiliary battery, GO to Pinpoint Test B
Do the main engine compartment battery and auxiliary battery pass the condition test?
Yes |
RETURN the battery to service. CLEAR the DTC and RETEST the system.
|
No |
If the analyzer reads REPLACE BATTERY or REPLACE-BAD
CELL or does not pass the battery condition test, INSTALL a new battery
for the one in question. REFER to: Battery (414-01 Battery, Mounting and Cables, Removal and Installation). or REFER to: Auxiliary Battery (414-01 Battery, Mounting and Cables, Removal and Installation).
