7 = Coolant Temp sensor or wiring.

A long blink = "10"
A short blink = "1"
DNS = Engine does not start
EON = Engine operates normally

BLINKS : PROBLEM, SYMPTOMS
No blinks: ECM malfunction, DNS
No blinks: ECM power / ground circuit malfunction, DNS
No blinks: ECM output line malfunction, DNS
No blinks: MIL circuit malfunction, EON
Stays lit: Data link circuit malfunction, EON
1 blink: MAP sensor circuit malfunction, EON
2 blinks: MAP sensor performance problem, EON
7 blinks: ECT sensor circuit malfunction, Hard start at low temp
8 blinks: TP sensor circuit malfunction, Poor performance on quick throttle operation
9 blinks: IAT sensor circuit malfunction, EON
11 blinks: Vehicle speed sensor circuit malfunction, EON
12 blinks: No. 1 Primary injector malfunction, DNS
13 blinks: No. 2 Primary injector malfunction, DNS
14 blinks: No. 3 Primary injector malfunction, DNS
15 blinks: No. 4 Primary injector malfunction, DNS
16 blinks: No. 1 Secondary injector malfunction, DNS
17 blinks: No. 2 Secondary injector malfunction, DNS
18 blinks: Cam pulse generator, no signal, DNS
19 blinks: Ignition pulse generator, no signal, DNS
21 blinks: No. 1 O2 sensor circuit malfunction (California only) , EON
22 blinks: No. 2 O2 sensor circuit malfunction (California only), EON
23 blinks: No. 1 O2 sensor heater malfunction (California only), EON
24 blinks: No. 2 O2 sensor heater malfunction (California only), EON
33 blinks: E2-PROM in ECM malfunction, EON
48 blinks: No. 3 Secondary injector malfunction, DNS
49 blinks: No. 4 Secondary injector malfunction , DNS

that is a 12vdc power problem.
the sensors are failing , many do to lost power. (12vdc electrical distribution power)
so use a voltemeter, i bet even at he cig lighter port the voltage drops
below 13.3v running, way below. infact.
are your battery terminals clean,
is the rested voltage at the battery terms 12.6v (keys in pocket)
no? then the battery is being discharged,

DTC P0705 - Transmission Range (TR) switch circuit malfunction (short to power supply)

DETECTION CONDITION
• Two or more range signals are input from the TR switch for 12 s or more.

Diagnostic support note:
• This is a continuous monitor (CCM).
• MIL illuminates if TCM detects the above malfunction condition in two consecutive drive cycles.
• PENDING CODE is available.
• FREEZE FRAME DATA is available.
• AT warning light illuminates.
• DTC is stored in TCM memory.

POSSIBLE CAUSE
• TCM malfunction
• Short to power supply in wiring harness between TR switch terminal A and TCM terminal 1D
• Short to power supply in wiring harness between TR switch terminal E and TCM terminal 2C
• Short to power supply in wiring harness between TR switch terminal D and TCM terminal 2B
• Short to power supply in wiring harness between TR switch terminal G and TCM terminal 2E
• Damaged connector between TR switch and TCM
• TR switch malfunction


Inspect swtich harnesses and test with OBD scanner reader tool.

KDL- Bravia blink codes (Australian):
2 times-Main power supply voltage error (12V, etc)
3 times-Malfunction of 3.3V line
4 times-Malfunction of 5V line
(Voltage Supply to FE, etc)
5 times-Malfunction of power supply for screen
6 times-Malfunction of inverter or overcurrent, etc
7 times-Abnormal temperature inside unit
8 times-Audio circuit error (amplifier, etc.)
9 times-Fan malfunction
10 times- Digital FE circuit error
11 times-Malfunction of Trident IC or around IC
12 times-BH board error
13 times -Malfunction of balancer
If this is correct the 5 blinks is the power supply having problems, I would much rather change the PS than replace the screen. Also if screen is determine bad, look for class action lawsuit on Sony for defective screen, i am told they know all about this.

The conditions that set this code are as follows:

The PCM monitors changes in input voltage on Brake Switch No. 1. If the PCM does not sense voltage changes at PCM terminal 82 when alternately accelerated and decelerated 8 times, the PCM determines that brake switch No. 1 has a malfunction

Possible Causes are:

• Brake Switch malfunction
• connector or terminal malfunction
• Short to power circuit between Brake Switch terminal D and PCM terminal 82
• Open circuit between Brake Switch terminal D and PCM terminal 82
• Malfunctioning PCM

C004E: Power Unit Cooling Fan Motor malfunction

Check the power supply fan for proper operation.
