ABS-433
P. ABS-433 Battery voltagePA. DTC information
Condition
If the control module registers that the battery voltage exceeds approx. 19 V for approx. 0.5 ms (exact voltage level depends on operating conditions) to control module connections #23 or #25, DTC ABS-433 is posted.
Substitute value
- ABS/TRACS is disabled.
- EBD is disabled.
Possible source
- The voltage of the battery charger/starting device connected is too high.
- The charging system is overcharging.
Fault symptom(s)
- If the ABS/EBD systems are disabled, there is a risk of the wheels (especially the rear wheels) locking when braking.
- In cars with TRACS, the anti-wheelslip system cuts out.
Fault-tracing begins with PB. Other DTCs, status notifications and status checks.

Other DTCs
- Note other DTCs
Select one of the above alternatives to continue
Alternative 1: PB2
Alternative 2: PB3
[PB2]
Status notification
Select one of the following alternatives to continue
Alternative 1: Fault-trace as per PC. Battery voltage too high. Permanent fault.
Alternative 2: Fault-trace as per PD. Battery voltage is too high. Intermittent fault.
[PB3]
Status check
- Engine on ticking-over
Connect a voltmeter between the battery plus and minus terminals
The voltmeter should indicate 12-15V when the battery is charging
If reading is OK: Fault-trace as per PD. Battery voltage is too high. Intermittent fault.
If reading is incorrect: Fault-trace as per PC. Battery voltage too high. Permanent fault.
PC. Battery voltage too high. Permanent fault
[PC1]
Check the connected battery charger and starter unit
Hint: It is important that the correct voltage is available when the battery charger or starter unit is connected to the battery. Charging with a voltage that is too great can trigger a DTC.
Check that the battery charger/starter unit are connected and the correct voltage is available.
Is the correct voltage available ?
Yes: PC2
No: PC3
[PC2]
Check the wiring system
Check the wiring system to ensure that the voltage charge is not too high.
Then continue with: PC4
[PC3]
Fault cause and action to be taken
The DTC has been caused by incorrect voltage supply. Set the correct voltage for the battery charger/starter unit.
Then continue with: PC4
[PC4]
Verification
Hint: After repair it is necessary to check that the fault has been rectified.
- Ignition off.
- Reconnect the connections, components etc.
- Engine ticking-over.
Connect a voltmeter between the battery plus and minus terminals.
The voltmeter should indicate 15V when the battery is charging.
If reading is OK: Fault corrected
If reading is incorrect: PC5
[PC5]
Fault-tracing information
The verification result shows that the fault persists.
Do you want to exit fault-tracing?
Yes: Fault not corrected
No: PC1
PD. Battery voltage is too high. Intermittent fault
[PD1]
Check the connected battery charger/starter unit
Hint: The DTC can be triggered if the battery charger or starter unit have been connected with an incorrect voltage.
Have the battery charger/starter unit been connected to the battery with an incorrect voltage?
Yes: PD2
No: PD3
[PD2]
Fault cause
The fault has been caused by incorrect voltage.
Then continue with: Fault corrected
[PD3]
Replacing a component
Test with a new charge regulator.
Then continue with: PD4
[PD4]
Fault-tracing information
For intermittent faults fault-tracing is not followed by a verification because the fault is not present at this moment.
Do you want to repeat fault-tracing?
Yes: PD1
No: Operation done
