My cruise control is not working....is that a fuse problem....also does a light come on when low on gas?

check all fuses!

Cruise control fuse # 31 10amp located in the under hood fuse / relay box an HZDFL fuse # 40 15amp located in the center console fuse box . If you pull the plastic side panel off of the right side of the console there is a fuse box inside . If the fuse are good the control module could be bad . Could also be turned off because the ABS has a problem .
DTC P1554 - do you know what a diagnostic trouble code is ?

The powertrain control module (PCM) has the ability to inhibit cruise control operation if conditions exist that would make cruise operation undesirable. The following conditions may inhibit cruise control operation:
• The engine speed is too high or too low.
• The vehicle speed is too high or too low.
• The traction control has been active for longer than 1 second.
• The vehicle acceleration or deceleration rate is too high

If the ABS light is on ,there are DTC'S stored in the system . Your best bet , take it to a GM dealer or someother qualified repair shop.

cruise controls are operated by
brake switch
VSS auto or clutch pedal -manual
tacho
control switch,
ECM
cruise control will not engage if the engine rpms are too low , vehicle speed is to slow
VSS unit is faulty (wiring)
switch is not making full contact
any one dropping out will cancel the control engagement

check cruise control fuse and check the brake lights see if brake light working because the brake light switch will deactivate cruise control when brakes is applied.if brake lights dont work either fuse blowed or switch bad.if all is good have vechicle code scan because cruise control control by PCM and vechicle speed sensor and thottle actuator control motor.

Look at your brake master cylinder, open the top to it, and check your brake fluid. If low, that is why the brake light is on. Or check to see if your emergency brake is pushed in. Check your fuses for the cruise control. Hope this helps, James Booth

I would check the fuse box. I have been having issues with it. My brother put in a stereo and then my cruise control no longer worked. At night when the lights come on in my car they go from high light to low without me doing it, so it has to be something with the fuse.

Start with the simple and check the fuses and the Stop lamp switch. Check your brake lights, if they're not working, the cruise won't work either. If they're not working, check the fuse for them, if the fuse is fine, then take it into the dealer, there's been a recall issued on the brake switch, so it should get fixed for free.
Cruise Control Disengaged
The powertrain control module (PCM) disengages the cruise control operation based on the signals from the following switches:

* The stop lamp switch
* The TCC brake/cruise release switch
* The clutch release switch, if equipped
* The cruise control On/Off switch

The TCC brake/cruise release switch and the stop lamp switch are mounted on the brake pedal bracket. When the brake pedal is applied, the normally closed TCC brake/cruise release switch opens and the normally open stop lamp switch closes. The PCM detects a low signal voltage on the TCC brake/cruise release switch signal circuit and a high signal voltage on the stop lamp switch signal circuit. When the clutch pedal is applied, the normally closed clutch release switch opens and the PCM detects zero voltage on the CCP switch signal circuit. The vehicle speed stored in the memory of the PCM will be erased when the cruise control On/Off button is turned OFF, or the ignition switch is turned OFF.

The Cruise Control System will disengage when the PCM detects that a driver override function has been active for approximately 60 seconds .

When the Cruise Control System is disengaged, the PCM sends a class 2 message to the instrument panel cluster (IPC) in order to deactivate the cruise control indicator.

Cruise Control Inhibited
The powertrain control module (PCM) inhibits the cruise control operation when any of the following conditions exist:

* A cruise control related DTC has been set.
* The vehicle speed is less than 40.2 km/h (25 mph) .
* The vehicle is in PARK, REVERSE, NEUTRAL, or 1st gear.
* The engine RPM is too low.
* The engine RPM is too high, with fuel cut off.
* The vehicle speed is too high, with fuel cut off.
* The system voltage is not between 9 volts and 16 volts .
* The Traction Control System (TCS) is active for more than 2 seconds .
Thank you for using Fixya and start with replacing the stop lamp switch. Even though the brake light work, it;s been known for that switch to cause your issue. that's way there was a recall for it.

check engine light has to be off for cruise to work thats how they made the car i dont like that but thats how it is

There are 3 places on the Rav4 where fuses can be located and checked. for the cuise control.

The back of the cruise control stacking switch has been know to fail (fall apart) and Toyota issued a TSB with replacement switch.

if it is the fuses then they most likely are related to cruise control system: Stop, Dome, Gauge and Igniton
The interior fuse box
The main engine fuse box (by brake fluid)
Cruise control ECU is under the glovebox.
Cruise control actuator is under hood (by driver side brake fluid/booster)Throttle position sensor (to detect if your foot is on gas pedal)
Cruise control switch on the clutch pedal too (if you have 5spd manual)
Brake lights are the deactivate signal for the cruise control

check for power supplies and brake fluid level. if to low the cruise will not work.
