if one of the computers is offline
no amount of coils or fuel pumps will fix it
have you tried the display diagnostics yet
Trip computer diagnostic codes
Hold mode and up arrow then turn key to on or start
Release buttons
then
Press Mode = Dash Part Number - e.g. 1731
Press Mode = Mode Switch Voltage - e.g. BV - - - 5.0
Press Mode = Battery Voltage - e.g. V 11.8
Press Mode = Petrol Sender Voltage - e.g. FUEL 02.6
Press Mode = LPG Sender Voltage - e.g. VL 5.0
Press Mode = Remaining Fuel - e.g. 38L
Press Mode = Instantaneous Fuel (Liters per Hour) - e.g. 12.8 L/H
Press Mode = Engine Coolant Temp - e.g. 63 C
Press Mode = Vehicle Speed - e.g. 45 KM/H
Press Mode = Tachometer - e.g. 2380
Press Mode = Park Lamps Switch - e.g. P OFF
Press Mode = Dash Trouble Codes - e.g. t 00 (Press up/down to scroll through any codes, these are not PCM, ABS, etc codes)
Press Mode = Dash Test - All gauges will move, lights will come on and buzzer will sound.
Turn key off will revert to normal dash
Dash trouble codes
Format is t then code number then history then current some have nu which I cant remember but believe was not used
Eg
t00-- is fuel gauge sender open circuit no history and no current faults
t16h- is abs history codes but no current fault
00 Fuel gauge sender unit — open circuit
01 Fuel gauge sender unit — short circuit
02 Fuel gauge sender unit — intermittent
03 Fuel gauge sender unit — open circuit
04 LPG gauge sender unit — open circuit
05 LPG gauge sender unit — short circuit
06 LPG gauge sender unit — intermittent
08 No serial data from ABS
09 No serial data from BCM
10 No serial data from ECC
11 No serial data from PCM
12 No serial data from SDM
13 No instrument poll from BCM
14 No serial communication
15 No Sub-clock
16 ABS or ABS/ETC fault logged
17 BCM fault logged
18 ECC fault logged
19 PCM fault logged
20 SDM fault logged
21 Trip switch short circuit
22 Trip switch button stuck
24 EE checksum error
25 ROM checksum error
