FAQ

What do I do if the OBD (On Board Diagnostic) Scanner displays a P1336 (Crankshaft position (CKP) system variation not learned) code.

The diagnostic code (P1336) is to tell you that the OBD has disabled the Misfire monitor, due to the crankshaft variation not being learned. This can happen if the PCM (computer) has been recently re-flashed for engine conversion, or where the engine & PCM were not from the same vehicle.

This re-learn procedure can be done by any GM Holden dealer via their Tech II programmer. For engine conversions the dealer may require donor vehicle original V.I.N. (Vehicle Identification Number) for dealer to gain access. This only applies to Holden Vehicles Manufactured in Australia.

This diagnostic code will disable the misfire monitor, and not warn the driver that the engine has entered a dangerous misfire event, which can cause catalyst damage & higher than usual emission readings.

This code should not effect the overall vehicle operation, and should not disable engine in any way.

System Scan: If encountering problems such as engine management light staying on, automatic transmission not shifting properly, speedo not working etc.

It is advisable to scan the system with Tech 2 or a good quality scan tool. Record all faults and advise us either by email, fax or phone. System can be manually scanned as per workshop manual procedure.

Where do I mount ECU? (Computer)

Most ECU's all mount either on the LH kick panel or above the Glove box. GEN IV LS-3 engine ECU mount on drivers side front inner guard behind headlight.

Cable-x not working?

Is it wired correctly Red = Ignition, Black = earth, White = signal input.
2) If connecting direct from PCM (Computer) speedo signal you need to use a 4.7k ohm pull up resistor.
3) Read instructions supplied in box and set the trim switches accordingly.

Auto Trans goes in to 3rd only.

Vehicle in limp home mode. Scan vehicle for fault codes.

Fuel pump not working.

Check all plugs for pins that may have become dislodged.

Cranking issues.

Place a test light on solenoid wire and check to see if there is power. If vehicle was previously an Auto check park neutral switch has been bridged.

Engine cranks and fires on start but cuts out when key is released.

Ignition by-pass wired wrong. Follow instructions provided.

Engine starts and runs but will not rev over 2000rpm and cuts out.

If on Holden 12volt with ballast resistor. The Ballast has not been by-passed. Follow instructions.

Vehicle fires but cuts out within 2 seconds

Has VAT's (Vehicle Anti Theft) been programmed out of ECU (Computer). CAE Performance Products provide this service.

Speedo and Tacho not working.

Check all wiring speed sensor and tacho signal
2) Depending on Speedo brand it may need 4.7k ohm pull-up resistor.

Pedal not working with TAC module.

Reprogram TAC - check and see if pedal assembly matches application.

AC re-gassed but still not switching by switch.

Check for positive switching at A/C switch. Bridge pressure switch.

GENIII loom into a VN had no positive feed into ECM (Computer).

Check for correct wiring down in kick panel. Positive is Pink wire, which is on with ignition.

Transmission not shifting gears

Check with ECU(Computer) scan tool: If low voltage code for trans. is logged. Check 12volt supply at trans plug (pink/blue wire)

Where do I fit temp. and oil sender's for my gauges on a LS1 - LS2 - LS3 - LS7?

You will need Temp-Sender adaptor kits from us and a T-piece for Oil Sender. Then simply screw into where factory oil sender is fitted at rear of engine. Temp Sender is to be fitted into Hex key bung at rear of driver's side cylinder head.

What Senders do we use to get factory oil and temp. gauges to work on a new engine transplant?

Original Senders from original engine will be required to be fitted for the Gauges to work correctly.

Which sump do I use on my VB to VS LS-1 LS-2 engine conversion?

If using the LS-3/GEN-4 VE Commodore engine you need to have the sump changed to Pre-VE to suit all early Commodore conversions. All earlier engines LS-1 and LS-2 use VT-VZ standard sump.
