Component: 1.8L R4/5VT 0001

Shop #: WSC 06441
2 Faults Found:
18010 - Power Supply Terminal 30: Voltage too Low
P1602 -- 35-10 - - - Intermittent

From the Ross-TechWiki

18010/P1602/005634

Possible Causes

Cables on the Battery were removed
Battery weak (voltage)
Generator Disfunction

Possible Solutions

Check Battery Cables
Check/Replace Battery
Check/Replace Generator

Special Notes

If multiple Control Module have Power Supply Faults stored, it's most likely to be one common Problem like the ones shown above. Otherwise when only one or two Control Modules have such Codes stored you better start searching at the individual Power Supply of these Modules.

Terminal 30 means unswitched battery power that is supplied even when the ignition is off. This is not referring to any physical terminal numbered 30.​

So, check the battery and the alternator.



16805/P0421/001057 - Warm Up Catalyst; Bank 1: Efficiency Below Threshold

Possible Causes

Warm Up Catalyst Bank 1 faulty

Possible Solutions

Check Warm Up Catalyst Bank 1
Set Readiness
Replace Warm Up Catalyst Bank 1
​

The description here is not helpful. From what I've been able to find, the usual first step is to replace the pre-cat lambda probe.

i was thinking lamdba, i have also had the battery disconected recently so i think that may be the issue of the 1st code
