Instrument Cluster Failure

[guest6018]

My Honda Jazz, first registered 12.08, has a failure with the instrument cluster. None of the gauges work and there is no information display i.e. mileage. If anyone has seen this fault before then any help to rectify it would be much appreciated.

Could just be the under dash fuses, either #1 10a or #22 7.5a, but why would they go?
If the gauge control module has developed a fault it will produce a code (B1152 ?) you can read it via the OBDII port.

There is a test facility hondafitjazz.com/manual3 > body > gauges > self diagnostic

Entering the self-diagnostic function (manual method)
Push and hold the SELECT/RESET switch button.
Turn the combination light switch (  ) ON.
Turn the ignition switch to ON (II).
Within 2−5 sec., turn the combination light switch (  ) OFF, then ON and OFF again.
Within 5 sec., release the SELECT/RESET switch button, and then push and release the button three times repeatedly.
NOTE:
While in the self-diagnostic mode, the dash lights brightness controller operates normally.
While in the self-diagnostic mode, the SELECT/RESET button is used to start the Beeper Drive Circuit Test and the Gauge Drive Circuit Check.
If the vehicle speed exceeds 2 km/h (1.2 mph) or the ignition switch is turned to LOCK (0), the self-diagnostic mode ends.
 
The Indicator Drive Circuit Check
When entering the self-diagnostic mode, the following indicators blink:
ABS indicator, brake system indicator, A/T gear position indicator, charging system indicator, cruise control indicator, cruise main indicator, EPS indicator, high beam indicator, high temperature indicator, immobilizer indicator, lights-on indicator, low temperature indicator, low oil pressure indicator, low fuel indicator, malfunction indicator lamp (MIL), seat belt indicator, security indicator, side airbag cutoff indicator, sequential sportshift mode shift indicator, safety indicators, SRS indicator.
The Beeper Drive Circuit Check
When entering the self-diagnostic mode, the beeper sounds five times.
Switch Input Check
After the beeper drive circuit check, you can check the switch input. The beeper sounds continuously when the ODO/TRIP button or the parking brake switch inputs are switched from OFF to ON: ODO/TRIP button, parking brake switch.
The LCD Segment Check
With ODO/TRIP display: When entering the self-diagnostic mode, all the segments blink five times.With multi-information display (MID): When entering the self-diagnostic mode, ‘‘···'' shows on the MID, and blink five times.
The Gauge Drive Circuit Check
When entering the self-diagnostic mode, the speedometer, the tachometer, the fuel gauge needles sweep from the minimum position to maximum position, then return to the minimum position.
NOTE:
After the beeper stops sounding and the gauge needles return to the minimum position, pressing the ODO/TRIP button starts the Beeper Drive Circuit Check (one beep) and the Gauge Drive Circuit Check again.
The check cannot be started again until the gauge needles return to the minimum position.
If the needles fail to sweep, or the beeper does not sound, replace the gauge control module.
 
etc .... etc .....

Ok, thanks for the information, I will give the self test a go and see what happens. The fault is a intermittent because if I disconnect the battery, leave it for a while and then connect it again then the cluster works as normal, but only lasts for a day or do then fails again. But disconnecting the battery does not always work and is getting less successful over time. Is the gauge control module actually the cluster itself or is it a separate module somewhere else?

[guest1372]

From spare part codes and the site linked earlier the gauges cluster & control module seem to be be one unit, 'Meters Assembly'.

But if it's intermittent fault, then it could be a poor connection at a fuse or plug, a poor ground, or an open circuit wire is another possibility. This happens when too much strain or bend is placed on a cable and time/temperature/vibration causes core failure. The first Jazzes with fly-by-wire throttles had a tight wire that was prone to intermittent then complete failure.

There is a 32 pin connector on the back of the gauges and the site linked earlier lists the expected voltage/continuity of the connections.
http://www.hondafitjazz.com/manual3/en/html_en/000000000000314.html if it all checks out then they suggest replacing the unit.

Bizarrely, mileage and service interval seem to be stored in the gauges rather than in the ECU, so swapping them requires someone with the ability to reprogram it.

I tried to get the self test to work but without success i.e. it had no response at all. There is a fault code present and it is U0155 F-CAN Malfunction, it will clear, but comes back after a few seconds. The 32P connector to the gauge cluster checked out ok, but some of the voltages that required to be battery voltage were not battery voltage and were approximately 1v below. I will continue with the fault finding as per the chapter on fault U0155.

Might be battery on its way out, or as other threads have discovered an intermittent faulty cell due to vibration failure. May be worth swapping the battery as you say the fault frequency is increasing, which ties in with a failing battery.
