KL: Shift Indicator Lamp (SIL)

KL: Introduction See: KL: Shift Indicator Lamp (SIL) - Introduction

KL1 CHECK SHIFT INDICATOR LAMP (SIL) OPERATION

Note: When the SIL is operating properly, it comes on when optimum shift speed is reached. The SIL will turn off after a shift has been completed or while in top gear.

• Drive vehicle through all forward gears.
• Look for the SIL to come on before the next upshift.
• Look for the SIL to be off after a shift has been completed or while in top gear.

Is SIL on all the time?
Yes

• KEY OFF. GO to KL4

.

No

• KEY OFF. GO to KL2

.

KL2 CHECK SIL CIRCUIT FUSE

• Remove SIL circuit fuse and inspect.

Is fuse OK?
Yes

• INSTALL SIL circuit fuse. GO to KL3

.

No

• REPAIR short circuit. REPLACE SIL circuit fuse.

KL3 CHECK SIL BULB

• Remove SIL bulb and inspect.

Is SIL bulb OK?
Yes

• GO to KL5

.

No

• REPLACE SIL bulb.

KL4 CHECK SIL CIRCUIT FOR SHORT TO GROUND IN HARNESS

• Shift transmission to highest gear.
• Disconnect PCM.
• Measure resistance between SIL circuit at PCM harness connector and battery negative post.

Is resistance greater than 10,000 ohms?
Yes

• REPLACE PCM (refer to Section 2, Flash Electrically Erasable Programmable Read Only Memory (EEPROM) See: Programming and Relearning\Flash Electrically Eraseable Programmable Read Only Memory - Flash EEPROM).

No

• REPAIR short circuit.

KL5 CHECK IGN START/RUN VOLTAGE TO SIL SOCKET

• SIL bulb removed.
• Transmission in any gear except top gear.
• Key on, engine off.
• Measure voltage of the SIL circuit between the SIL socket and chassis ground.

Is the voltage greater than 10.5 volts?
Yes

• KEY OFF. GO to KL7

.

No

• KEY OFF. RECONNECT SIL bulb. GO to KL6

.

KL6 CHECK OPERATION OF TOP GEAR SWITCH

• Transmission in any gear except top gear.
• Disconnect top gear switch.
• Measure resistance of the top gear switch.

Is resistance less than 5.0 ohms?
Yes

• REPAIR open circuit.

No

• REPLACE top gear switch.

KL7 CHECK SIL CIRCUIT FOR OPEN IN HARNESS

• SIL bulb removed.
• Disconnect PCM.
• Measure resistance between SIL circuit at PCM harness connector and SIL bulb socket.

Is resistance less than 5.0 ohms?
Yes

• REPLACE PCM (refer to Section 2, Flash Electrically Erasable Programmable Read Only Memory (EEPROM) See: Programming and Relearning\Flash Electrically Eraseable Programmable Read Only Memory - Flash EEPROM).

No

• REPAIR open circuit.
