Hi Lotus Drivers Club

I am wondering if you can help.

I am thinking of buying a Elan SE, but there is an engine warning light showing on the dash.

Is there some way I can find out what the warning is without going to a Lotus Garage?

Your assistance is appreciated.

Mike

Hi Mike. I suggest you look on www.elancentral.com you should be able to find what all the warning lights are for there.

Hope you get the answer you want and become a M100 Elan owner.

Hi Mike

You really need to plug it in and get the codes off to be able to tell what the problem is.

My local car shop that sells parts/accessories etc will plug their reader in if I am struggling for anything. Armed with the codes you can google them and normally find out whats wrong.

 

The Elan M100 site is a good source of information, below is the common fault codes for M100s 

Error Codes

Code Fault
12 None
13 O2 sensor (or circuit) malfunction -- see CommonParts replacement
14 High Coolant Temperature (relative to other measurements)
15 Low Coolant Temperature (relative to other measurements) -- see CTS write-up
21 Throttle Position Sensor (Signal Voltage High)
22 Throttle Position Sensor (Signal Voltage Low)
23 Manifold Air Temperature Low (relative)
24 Vehicle Speed Sensor
25 Manifold Air Temperature High (relative)
31 Manifold Absolute Pressure (Turbo Overboost)
33 Manifold Absolute Pressure Sensor (High voltage / Low vacuum)
34 Manifold Absolute Pressure Sensor (Low voltage / High vacuum)
35 IAC error IAC motor not controlling the engine to the desired speed
41 Cam Angle Sensor (Hall Effect Sensor) -- see CAS write-up
42 Electronic Spark Timing circuit
43 Electronic Spark Control (Knock Sensor Circuit)
44 Lean exhaust
45 Rich exhaust
51 ECU Fault ($$$OUCH$$$--get a new ECU)
53 Over voltage (system voltage high)
54 CO-Potentiometer circuit
65 Fuel injector driver circuit (or output) problem

Hi Mike. Take a look at Elan Scan. I used this several times when I owned an S2 Elan several years ago. The software is simple but works with the right cable which I believe you can still get hold of through ElanCentral: http://elanm100.com/repairs-2/diagnostics

Oh yea, I remember carrying a paperclip in the glove box of my M100 😂
