power steering control unit
my 1988 rx7 GTU is making beeping noises after like a few minutes, from the unit. i pulled the plug and it stopped, but then i lost power steering. plugged it back in and got the power steering back but the beeping comes back.
it beeps 5 times and pauses, and then repeat.... what does that mean? |

Probably the power steering computer telling you there is a problem with the system. The number of beeps before pausing will indicate the problem. 1-beep, pause, repeat - in case abnormality of speed sensor signal: In case broken wires or short circuits occur to sensors or harnesses, the buzzer sounds 60-seconds after the engine speed signal of 2200 rpm continues for 18-seconds. 2-beeps, pause, repeat - in case abnormality of engine speed signal: The buzzer sounds twice and repeats when the vehicle speed signal is missing input and/or no engine speed signal is found (short circuit, broken wire, etc.) 3-beeps, pause, repeat - in case abnormality of stepping motor signal: The buzzer sounds when there are broken wires or short circuits in coils or harnesses. 4-beeps, pause, repeat - in case abnormality of the power steering microcomputer: The buzzer sounds 4 and repeats when there are circuit troubles other than with the micro computer. 5-beeps, pause, repeat - in case abnormality of steering sensor signal: Steering sensor is mis-aligned or failed or steering wheel has been improperly installed. |
thanks!
